Embodiment 1 The program performance test method.

The method of this embodiment will be described in detail below with reference to FIG. 1.

In FIG. 1, S100, preset acquisition control parameters for performance test indicators of the PHP program to be tested, and the acquisition control parameters at least include: acquisition frequency of performance test indicators.

Specifically, the frequency of collecting performance test indicators in this embodiment is mainly used to control the frequency of collection of performance test indicators.

The collection control parameters in this embodiment may also be included according to actual test requirements: a total acquisition control switch, a control switch for real-time monitoring performance test indicators, an acquisition control switch for a function occupying a CPU condition, an acquisition control switch for a function occupying a memory condition, and a function. One or more (or even all) of the acquisition control switches of the number of calls and the acquisition control switches of the function response time within a predetermined time interval. In addition, the collection control parameter in this embodiment may further include: one or two of path information and file name information of the text file, and path information and database name information of the database. Of course, this embodiment may also add or delete corresponding parameter items according to specific test requirements in actual applications.

The above total acquisition control switch is mainly used to determine whether to execute the acquisition operation of the PHP program performance test indicator, for example, the total acquisition control switch is set to on, indicating that the performance test indicator acquisition operation is performed during the running of the PHP program; the total acquisition control switch is set to Off, indicating that the collection operation of the PHP program performance test indicator is not executed during the running of the PHP program.

The control switch of the real-time monitoring performance test indicator is mainly used to determine whether the collected performance test indicator needs to be monitored in real time. For example, the real-time monitoring performance test indicator is set to ON, indicating that the real-time display should be performed every time the performance test indicator is collected. The performance test indicator; the real-time monitoring performance test indicator is set to off, indicating that all the performance test indicators collected do not need to be displayed in real time.

The above-mentioned function occupies the CPU situation. The acquisition control switch is mainly used to determine whether to collect the operation test index of the function occupying the CPU. If the function occupies the CPU, the acquisition control switch is set to ON, indicating that each time the PHP program is running. When performing the performance test index collection operation, the performance test index of the function occupying the CPU condition should be collected; the acquisition control switch of the function occupying the CPU condition is set to off, indicating that each time the performance test indicator is collected during the running of the PHP program There is no need to collect the performance test indicators of the function occupying the CPU.

The above-mentioned function occupies the memory condition of the acquisition control switch is mainly used to determine whether to collect the operation test indicator of the memory usage of the function, such as the function of the memory occupancy of the acquisition control switch is set to open, indicating that each time the PHP program is running When performing the performance test indicator collection operation, the performance test index of the memory occupied by the function should be collected; the acquisition control switch of the function occupying the memory condition is set to off, indicating that each time the performance test indicator is collected during the running of the PHP program There is no need to collect performance test indicators for function memory usage.

The acquisition control switch of the above function in the predetermined time interval is mainly used for determining whether to perform the collection operation function on the performance test index of the function call time in a predetermined time interval, such as the acquisition control switch setting of the function call time within a predetermined time interval. For the open, it means that the performance test index of the function call time in the predetermined time interval should be collected every time the performance test indicator is collected during the running of the PHP program; the function of the function is called in the predetermined time interval. Set to off, it means that the performance test indicator of the number of calls of the function in the predetermined time interval is not required for each time the performance test indicator is collected during the running of the PHP program.

The above-mentioned function response time acquisition control switch is mainly used to determine whether to collect all the function response time performance test indicators, such as the function response time acquisition control switch is set to on, indicating that each execution is performed during the PHP program running process. All performance response indicators should be collected during the acquisition of performance test indicators; the acquisition control switch that takes up the CPU condition of the function is set to off, indicating that each time the performance test indicator is collected during the running of the PHP program There is no need to collect the performance test indicators of the function occupying the CPU.

The path information and file name information of the above text file are mainly used to describe that each time the collected performance test indicators are temporarily stored in the text file, the performance test indicators should be based on the path information and file name information of the text file. Temporarily stored in the corresponding text file; or in the case that the performance test indicators collected each time are finally stored in the text file, the performance test indicators should be stored in the corresponding text according to the path information and the file name information of the text file. In the file.

The path information and database name information of the above database are mainly used to describe that each time the collected performance test indicators are directly stored in the database, the performance test indicators should be directly stored in the corresponding data according to the path information and database name information of the database. In the database; or in the case where the performance test indicators collected each time are stored in a text file and the performance test indicators in the text file are stored in the database at the end of the performance test, the path information of the database should be The database name information stores the performance test metrics in the corresponding text file in the corresponding database.

S110. Acquire pre-set acquisition control parameters in a process of simulating access to the server by a mass of users to test the performance of the PHP program in the server.

Specifically, the PHP program in this embodiment runs on a server, and the server is accessed by a large number of users (such as millions of users), so that any one of the PHP programs running on the server is included. It is possible for a function to be called multiple times (such as tens of thousands or even millions) in a short interval of time.

The operation of obtaining pre-set acquisition control parameters is usually performed at the beginning of the PHP program performance test. The acquisition control parameter can be in the form of a configuration file, and the configuration file can be pre-set in the server where the tested PHP program is located, so that in the PHP program performance test process, it can be conveniently obtained from the configuration file stored locally by the server. Collect control parameters.

The specific values of each parameter item in the acquisition control parameters can be changed according to the requirements of the PHP program performance test. In order to conveniently set the value of each parameter item in the acquisition control parameter, a setting interface of the acquisition control parameter may be displayed at the beginning stage of the PHP program performance test, and the name of each parameter item included in the acquisition control parameter and each parameter are displayed in the interface. The current value of the item (such as the default value), the user can set the specific value of each parameter item through the interface. For example, the acquisition frequency of the performance test indicator is set to a predetermined time interval through the interface, and the total acquisition control switch is Set the value to ON, set the value of the control switch of the real-time monitoring performance test indicator to off, set the acquisition control switch that takes up the function of the CPU to ON, and set the acquisition control switch of the function to occupy the memory to ON. The acquisition control switch of the number of calls is set to ON within a predetermined time interval, the acquisition control switch of the function response time is set to ON, the path information and file name information of the text file, the path information of the database, and the database name information are then set, and then passed Click the save button in the acquisition control parameter setting interface, etc. Above provided specific value locally stored key parameters (e.g. stored in the local configuration files).

A specific example of a configuration file is as follows:

1, define ('XHPROF_ENABLE', true); / / whether to open the PHP program performance test indicators acquisition operation, that is, set the value of the total acquisition control switch;

If(XHPROF_ENABLE==true&&function_exists('xhprof_enable')){

Xhprof_enable();

}

Among them, "function_exists('xhprof_enable')" in the above statement is mainly used to judge whether xhprof_enable() exists, so that the program logic is more rigorous and the program runs more stably;

2, define ('XHPROF_TYPE, 0); / / 0: is performance, 1: is a function (the performance refers to the performance test application scenario, that is, for large-volume user access; the function refers to the manual performance test application The scenario, that is, the case where the tester manually clicks to implement user access, that is, the case where the user has a small amount of access);

If(XHPROF_TYPE==1){

$percent=1; adjust the acquisition frequency of performance test indicators for each user access;

$run_id=$xhprof_runs->save_run($xhprof_data, "hx"); turn on page monitoring and generate a link to collect data on the test page;

Echo"<a href='/xhprof_html/index.php?run=".$run_id."&source=sourcejoy'>view</a>"; (This statement indicates that after the performance test is completed, all collected data will be tested The page automatically generates a link to facilitate the user to view the performance test results);

}

If(XHPROF_TYPE==1){

}

3, define ('XHPROF_LOG_DATA', '/usr/local/apache2/htdocs/xhprof/'); / / log information storage path;

4, define ('PERCENT', 1); / / record the frequency of the log information, that is, set the value of the acquisition frequency of performance test indicators;

Generate a random number by the function $percent=mt_rand(1, PERCENT);

If($percent==1){

Xhprof_enable(XHPROF_FLAGS_CPU+XHPROF_FLAGS_MEMORY);

} (This statement indicates that the performance test indicator for each acquisition should contain details of the CPU usage of the function and the details of the function occupying MEMORY)

5, define ('PAGEVIEW', true); / / whether to open page monitoring, that is, each time the data is collected will generate a page containing detailed collection data, the page is the test page mentioned above to view performance test results ;

If (turn on performance test &PAGEVIEW==true){

$run_id=$xhprof_runs->save_run($xhprof_data,"hx");

} (This statement indicates the file id stored in the collected performance test indicator, which can be used to automatically generate a test page showing the performance test results)

Else

Do not save the monitoring page;

6, define ('BUILTINS', true); / / monitor PHP internal function performance (special need to be noted, PHP internal functions are some of the commonly used public functions that PHP comes with, not written by PHP programmers, usually Under the PHP program performance test, the code of the PHP internal function will not be checked.

If(BUILTINS==true){

Xhprof_enable(XHPROF_FLAGS_NO_BUILTINS);

} (This statement means to close the collection operation of PHP internal function performance test indicators)

7, define ('CPU_MONITOR', true); / / Whether the monitor function occupies the details of the CPU (such as the function of the CPU in the case of the PHP internal function, and the CPU does not contain the PHP internal function) Time), the default only monitors the CPU usage time when the function does not contain PHP internal functions. This option can be used to count more detailed CPU usage information. In this embodiment, the CPU time of the function is collected, so that the function can be passed. The CPU usage time calculates the percentage of CPU occupied by the function;

If(CPU_MONITOR==true){

Xhprof_enable(XHPROF_FLAGS_CPU);} (This statement indicates that the function takes up CPU details when including PHP internal functions)

8, define ('MEM_MONITOR', true); / / Whether the monitor function occupies memory details (such as in the case of PHP internal functions, the function takes up memory and the function occupies memory without including PHP internal functions, You can also count the data such as the peak memory usage. By default, only the number of bytes occupied by the function in the case of not including PHP internal functions is monitored. This option can be used to count more detailed memory usage information.

If(MEM_MONITOR==true){

Xhprof_enable(XHPROF_FLAGS_MEMORY); (This statement indicates that the function occupies memory when the PHP internal function is included)

S120: Collect performance test indicators of each function in the PHP program during the test according to the acquisition control parameter.

Specifically, in this embodiment, the collection operation of the performance test indicator should be performed according to the set value of each parameter item in the acquisition control parameter, a specific example:

When the setting value of the total acquisition control switch in the acquisition control parameter is ON, the acquisition operation of the performance test indicator should be performed according to the acquisition frequency of the performance test indicator; the setting value of the total acquisition control switch in the acquisition control parameter is not In the case of ON, no acquisition of any performance test indicators will be performed.

In the case where the setting value of the control switch of the real-time monitoring performance test indicator is ON, it should be based on the nature. The acquisition frequency of the test indicator can be displayed to the user in real time when the performance test indicator is collected. For example, a link is generated according to the collected performance test indicator, and the link is displayed in the monitoring page in real time. The content of the link; if the setting value of the control switch of the real-time monitoring performance test indicator is not on, the above-mentioned real-time display operation will not be performed.

In the case that the setting value of the acquisition control switch of the function occupying the CPU is ON, the performance test index of the function occupying the CPU condition should be collected each time the performance test indicator is collected according to the acquisition frequency of the performance test index. In the case that the setting value of the acquisition control switch of the function occupying the CPU is not on, the acquisition function does not need to occupy the CPU when the performance test indicator is collected every time according to the acquisition frequency of the performance test indicator. Performance test indicators.

In the case that the setting value of the acquisition control switch of the function occupying the memory is on, the performance test index of the function occupied memory should be collected each time the performance test indicator is collected according to the acquisition frequency of the performance test index. In the case that the setting value of the acquisition control switch of the function occupying the memory is not on, the acquisition function does not need to occupy the memory when performing the performance test index acquisition operation according to the acquisition frequency of the performance test indicator. Performance test indicators.

In the case that the set value of the acquisition control switch of the function in the predetermined time interval (such as the number of calls in the unit time) is on, the Xhprof method call count statistics function should be turned on, so that the collection according to the performance test index is performed. Each time the performance of the performance test indicator is collected, the performance test indicator of the function call time within a predetermined time interval can be collected; the number of times the function is called within a predetermined time interval (such as the number of times the function is called in a unit time) If the setting value of the acquisition control switch is not on, the Xhprof call count statistics function may not be enabled. Therefore, when the performance test indicator collection operation is performed according to the acquisition frequency of the performance test indicator, it will not be collected. The performance test indicator for the number of times the function is called within a predetermined time interval.

When the setting value of the acquisition control switch of the function response time is ON, the function response time statistics function of Xhprof should be turned on, so that each time the performance test indicator is collected according to the acquisition frequency of the performance test indicator, The performance test indicator of the response time of each function is collected; if the setting value of the acquisition control switch of the function response time is not on, the function response time statistics function of Xhprof may not be turned on, so that the performance test indicator is based on the performance test The acquisition frequency of each time the performance test indicator is collected, the response time of each function is not collected.

In this embodiment, the function identifier, the CPU occupied by the function, the memory occupied by the function, the number of times the function is called in a predetermined time interval, and the response time of the function are collected by calling the corresponding API (Application Programming Interface) provided by Xhprof. Performance parameter indicator.

A specific example of obtaining performance parameter indicators is:

$mu=$PerformaceInfo['mu']; (mu indicates the number of bytes of memory occupied by the function acquired by the acquisition, and the unit is byte)

$wt=$PerformaceInfo['wt']; (wt represents the time of the function response obtained by the acquisition)

$ct=$PerformaceInfo['ct']; (ct indicates the number of times the function acquired by the acquisition is called within a predetermined time interval)

$cpu=$PerformaceInfo['cpu']; (cpu represents the CPU time (in microseconds, ie one millionth of a second) spent by the function acquired by the acquisition)

$wt=$wt/1000; (The number of bytes of memory occupied by the function can be obtained by this calculation, and the unit is KB)

Since the PHP program performance test usually simulates a large number of users (such as a million users or more) to access the server, so each function in the PHP program is called when the performance test indicators are collected, This will bring a large resource consumption to the server, which will bring greater pressure on the server, which will affect the accuracy of the PHP program performance test. In this embodiment, by collecting the performance test indicators according to the acquisition frequency of the performance test indicators, it is possible to avoid the phenomenon that the performance test indicators are collected when each function in the PHP program is called, so that the obtained PHP program performance test result can be obtained. more acurrate.

S130. Store each performance test record including the function identifier and the performance test indicator generated by each acquisition in the PHP program in the same database.

Specifically, all performance test records including the function identifier and the performance test indicator obtained by the multiple collections in this embodiment are finally stored in the same database, so as to perform subsequent performance analysis operations; and, the database is stored in the manner of a database. All the performance test records obtained during the performance test of the PHP program can also conveniently compare the performance test results of the PHP program before and after optimization, which is beneficial to the testers to weigh the advantages and disadvantages of optimizing the PHP program.

The specific implementation methods of all the collected performance test records stored in the same database are as follows:

Implementation method 1. In the configuration file, both the path information and the file name information of the text file are set, and the path information of the database and the database name information are set, in the process of running the PHP program, according to the frequency of collection of performance test indicators And the performance test records including the function identifier and the performance test indicator collected by the other corresponding parameter items in the acquisition control parameter are first stored in the text file according to the path information and the file name information of the text file in the configuration file, After the PHP program finishes running, all the performance test records in the text file are transferred to the database according to the path information of the database in the configuration file and the database name information.

Implementation 2: The path information and file name information of the text file are not set in the configuration file, but in the case where the path information of the database and the database name information are set, the acquisition frequency of the performance test indicator is used in the running process of the PHP program and Each performance test record containing the function identifier and the performance test indicator collected by other corresponding parameter items in the acquisition control parameter is directly stored in the database according to the path information and database name information of the database in the configuration file.

The above performance test record can be in the form of a log provided by Xhprof. The function identifier included in the performance test record may be identification information such as a function name that can uniquely identify a function in the PHP program; the content of the performance test record other than the function identifier depends on the parameter item in the acquisition control parameter. . From the perspective of comprehensive analysis of PHP performance, performance test records usually include the CPU usage of the function, the memory usage of the function, the number of times the function is called within a predetermined time interval, and the response time of the function.

The CPU usage of the above function can be specifically as follows: the CPU usage of the function and/or the occupation time of the CPU by the function; the memory usage of the above function can be specifically: the function to the memory occupancy rate and/or the function to the memory occupation time, etc.; The number of times a function can be called at a predetermined time interval can be specifically: the number of times the function is called by other functions in a unit time and/or the number of times the function calls other functions in a unit time; the response time of the above function can be specifically as follows: The time it takes for the call to start until the function returns the corresponding result.

S140. Determine performance of a function in the PHP program according to the performance test record stored in the database.

Specifically, in this embodiment, statistics are performed on each performance test record stored in the database, and the statistical result is analyzed to determine the performance of the function in the PHP program. The variousities stored in the database The test record can be statistically calculated as follows: statistical calculations (such as averaging) are performed on the performance test indicators belonging to the same function. The analysis of the statistical results determines that the performance of the function in the PHP program can be specifically as follows: the statistical calculation result of the performance test indicator is compared with the corresponding preset threshold value, and the performance test index exceeding the threshold value is selected, and the selected performance test is selected. The indicator and its associated function can be displayed to the test user. The function of the selected performance test indicator belongs to the function that the tester needs to pay attention to; for example, the CPU can be selected separately by statistical analysis of the performance test record in the database. The function of function ranking can be realized by the function of the top 10 functions with the most memory, the most memory, the most frequently called, and the slowest response time. The tester can analyze and improve the function that is located. The above-mentioned preset threshold may be a threshold set in advance according to test experience. If during the PHP program performance test, the collected performance test records need to be presented to the tester in real time, the performance test record exceeding the preset threshold may be displayed in different colors, such as the font is red or highlighted. .

In addition, all the performance test indicators corresponding to the function of the selected performance test indicator can be presented to the tester in the form of a line chart, a statistical table or a text file; the line chart can make the tester more intuitive and convenient. Improved function for positioning.

In the case of function analysis using a line graph, the abscissa of the two-dimensional coordinate system can represent time, and the ordinate of the two-dimensional coordinate system can represent the numerical value of the performance test index, so that a performance test indicator of a function can be based on The corresponding acquisition time is represented in the two-dimensional coordinate axis, so that the plurality of performance test indicators of the function form a broken line.

A plurality of polylines formed by a plurality of performance test indicators of a function may be represented in the same two-dimensional coordinate system; for example, four polylines of a function are shown in the same two-dimensional coordinate system, and the four polylines are respectively The first polyline formed by all the functions of the function occupying the CPU condition, the second polyline formed by occupying the memory condition for all functions of the function, and the number of calls for all functions of the function in a predetermined time interval Three polylines, and a fourth polyline formed for all function response times of the function.

In addition, multiple fold lines formed by the same performance test index of multiple functions may be represented in the same two-dimensional coordinate system; for example, four fold lines of four functions may be shown in the same two-dimensional coordinate system, and the four fold lines The first polyline formed by all the functions belonging to the first function occupying the CPU condition, the second polyline formed by all the functions belonging to the second function occupying the CPU condition, and belonging to the third All functions of a function occupy the third polyline formed by the CPU condition and the fourth polyline formed by the CPU condition of all functions belonging to the fourth function.

In this embodiment, the existing drawing plug-in can be used to draw the above-mentioned line graph. For example, the performance test record selected from the performance test record of the database is provided to the drawing plug-in according to a preset manner, so that the drawing plug-in can receive according to the same. The data obtained draws the above line chart.

In this embodiment, by analyzing the performance test records recorded in the database, the tester can conveniently locate the performance bottleneck of the PHP program, and the performance test record recorded in the database can be conveniently obtained by using other test tools. The test results are combined and analyzed to meet the testing needs of a variety of PHP programs.

Set the acquisition control switch of the function to the number of calls in the predetermined time interval to ON, set the acquisition control switch of the function response time to ON, set the path information and file name information of the text file, and the path information and database name information of the database. Then, click on the save button in the acquisition control parameter setting interface. Etc., so that the specific parameter item setting values stored in the local configuration file storage module 200.

The acquisition module 220 is mainly configured to collect performance test indicators of each function in the PHP program during the test according to the acquisition control parameters.

Specifically, the collection module 220 should perform the collection operation of the performance test indicator according to the set value of each parameter item in the acquisition control parameter obtained by the acquisition module 210, a specific example:

In the case that the setting value of the total acquisition control switch in the acquisition control parameter is ON, the acquisition module 220 should perform the acquisition operation of the performance test indicator according to the acquisition frequency of the performance test index; the total acquisition control switch in the acquisition control parameter If the set value is not on, the acquisition module 220 does not perform any acquisition operation of the performance test indicator.

In the case that the setting value of the control switch of the real-time monitoring performance test indicator is ON, the acquisition module 220 should perform the performance test indicator collected in real time each time the performance test indicator is collected according to the acquisition frequency of the performance test indicator. Displayed to the user, such as based on the collected performance test indicators A link is generated, and the content of the link is displayed in real time in the monitoring page; if the setting value of the control switch of the real-time monitoring performance test indicator is not on, the collecting module 220 does not perform the above-mentioned real-time display operation.

In the case that the setting value of the acquisition control switch of the function occupying the CPU is ON, the acquisition module 220 should collect the CPU usage of the function when the performance of the performance test indicator is performed every time according to the acquisition frequency of the performance test index. Performance test indicator; in the case that the setting value of the acquisition control switch of the function occupying the CPU is not on, the acquisition module 220 does not need to collect each time the performance of the performance test indicator is performed according to the acquisition frequency of the performance test indicator. The function takes up the CPU condition as a performance test indicator.

In the case that the setting value of the acquisition control switch of the function occupying the memory is on, the acquisition module 220 should collect the memory occupied by the function each time the performance of the performance test indicator is performed according to the acquisition frequency of the performance test index. Performance test indicator; in the case that the setting value of the acquisition control switch of the function occupying the memory is not on, the acquisition module 220 does not need to collect each time the performance test indicator is collected according to the acquisition frequency of the performance test indicator. The function takes up the memory condition as a performance test indicator.

In the case that the setting value of the acquisition control switch of the function in the predetermined time interval (such as the number of calls in the unit time) is ON, the acquisition module 220 should enable the method call counting function of Xhprof, so that the acquisition module 220 is According to the acquisition frequency of the performance test indicator, each time the performance test indicator is collected, the performance test index of the function call time in the predetermined time interval can be collected; the function is called in the predetermined time interval (such as the function in the unit) In the case that the setting value of the acquisition control switch is not on, the acquisition module 220 may not enable the Xhprof call count statistics function, so that the acquisition module 220 performs performance each time according to the acquisition frequency of the performance test indicator. When the test indicator is collected, the performance test indicator of the number of times the function is called within a predetermined time interval is not collected.

In the case that the setting value of the acquisition control switch of the function response time is ON, the acquisition module 220 should enable the function response time statistics function of Xhprof, so that the acquisition module 220 executes the performance test index each time according to the acquisition frequency of the performance test indicator. During the acquisition operation, the performance test index of each function's response time can be collected; if the set value of the function control switch of the function response time is not on, the acquisition module 220 can not open the Xhprof function response time statistics. Function, such that the acquisition module 220 performs performance test indicators each time according to the acquisition frequency of the performance test indicators. When the acquisition operation is performed, the performance test index of the response time of each function is not collected.

The collection module 220 can collect the function identifier, the CPU usage of the function, the memory occupied by the function, the number of times the function is called within a predetermined time interval, and the response time of the function, etc. by calling the corresponding API (Application Programming Interface) provided by Xhprof. Performance parameter indicator.

Since the PHP user usually simulates the access of the server during the performance test of the PHP program, if each function in the PHP program is called, the acquisition module 220 performs the performance test index collection, which will bring the server a comparison. Large resource consumption, which puts a lot of pressure on the server, which will affect the accuracy of PHP program performance testing. The collection module 220 in this embodiment collects the performance test indicators according to the collection frequency of the performance test indicators, and can avoid the phenomenon that the performance test indicators are collected when each function in the PHP program is called, so that the obtained PHP can be obtained. The results of the program performance test are more accurate.

The recording module 230 is mainly configured to store each performance test record including the function identifier and the performance test indicator formed by each acquisition in the PHP program running process in the same database.

Specifically, all performance test records that are collected by the collection module 220 and that include the function identifier and the performance test indicator are finally stored in the same database by the recording module 230, so that the performance module 240 performs subsequent performance analysis operations; The recording module 230 stores all the performance test records obtained during the performance test of the PHP program in a database manner, and can also facilitate the tester to compare the performance test results of the PHP program before and after optimization, which is beneficial for the tester to weigh the optimization of the PHP program. Pros and cons.

The specific implementation manners of the recording module 230 storing all the performance test records collected by the collection module 220 in the same database are as follows:

Implementation mode 1: In the configuration file, both the path information and the file name information of the text file are set, and the path information of the database and the database name information are set. In the running process of the PHP program, the collection module 220 according to the performance test index The performance test records collected by the acquisition frequency and other corresponding parameter items in the acquisition control parameters, including the function identifier and the performance test indicator, are recorded by the recording module 230 according to the path information and file name information of the text file in the configuration file. Stored in the text file, after the PHP program finishes running, the recording module 230 further stores all the performance test records in the text file in the database according to the path information of the database in the configuration file and the database name information.

Implementation 2: In the configuration file, the path information and the file name information of the text file are not set, but in the case where the path information of the database and the database name information are set, during the running of the PHP program, the collection module 220 according to the performance test index The performance test records including the function identifier and the performance test indicator collected by the acquisition frequency and other corresponding parameter items in the acquisition control parameter are stored by the recording module 230 directly according to the path information and database name information of the database in the configuration file. In the database.

The performance module 240 is primarily configured to determine the performance of functions in the PHP program based on performance test records stored in the database.

The performance module 240 performs statistics on the performance test records stored in the database. The performance module 240 performs statistical calculations (such as averaging) on the performance test indicators belonging to the same function. The performance module 240 analyzes the statistical result to determine the performance of the function in the PHP program. The performance module 240 compares the statistical calculation result of the performance test indicator with a corresponding preset threshold value, and selects a performance test indicator that exceeds the threshold. The performance module 240 can display the selected performance test indicators and the functions to which they belong to the tester. The function of the selected performance test indicators belongs to a function that the tester needs to pay attention to; for example, the performance module 240 can pass through the database. The statistical analysis of the performance test records selects the top 10 functions that occupy the most CPU, the most memory, the most frequently called, and the slowest response time, to achieve function positioning, and the tester can target the function. Analyze improvements. The above preset thresholds can be used by testers to preset thresholds based on test experience. If the performance test record collected by the acquisition module 220 needs to be presented to the tester in real time during the performance test of the PHP program, the performance test record exceeding the preset threshold may be displayed in different colors, such as the font being red or high. Bright mode display.

In addition, all the properties corresponding to the function to which the performance test indicator selected by the performance module 240 belongs The test indicator can be presented to the tester by the performance module 240 in the form of a line chart, a statistical table or a text file; the line chart can make the tester more intuitive and convenient to locate the function to be improved.

The tester performance module 240 can use the existing drawing plug-in to draw the above-mentioned line graph. For example, the performance module 240 provides the performance test record selected from the performance test record of the database to the drawing plug-in according to a preset manner, thereby drawing The plugin can draw the above line graph based on the data it receives. For details about the line drawing, refer to the description in the above method embodiment, and the description is not repeated here.

The performance module 240 can easily locate the performance bottleneck of the PHP program by analyzing the performance test records recorded in the database, and the performance test record recorded in the database can be conveniently obtained by using other test tools. The test results are combined and analyzed to meet the testing needs of a variety of PHP programs.
