Herein, any number of elements in the figures is for illustration and not limitation, and any designation is for distinction only and does not have any limiting meaning.

The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

SUMMARY OF THE INVENTION

The inventors found that the existing stress test needs to build a test environment or a high simulation environment, which requires high resources; and because the real online environment cannot be completely simulated, the accuracy of the test results is low.

In view of this, the present invention provides a stress testing method and device, which utilizes the online data of the system under test to generate stress test data, and directly tests the system under test in the online environment, so there is no need to build an additional test environment or high-simulation environment , saving costs and resources, and can improve the accuracy of test results.

Having introduced the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below.

Exemplary method

A stress testing method according to an exemplary embodiment of the present invention is described below with reference to FIG. 1 .

FIG. 1 schematically shows a flow chart for implementing a stress testing method according to an embodiment of the present invention. As shown in FIG. 1 , the stress testing method according to an embodiment of the present invention includes the following steps:

S11: Obtain online data of the system under test;

S12: Use online data to generate stress test data;

S13: Send the stress test data to the online environment of the system under test.

Through the above process, the embodiment of the present invention uses the online data of the system under test to generate stress test data, and sends the generated stress test data to the online environment of the system under test, so as to test the system under test in the online environment, so there is no need to An additional test environment or a high-simulation environment is built, which saves costs and resources; and because there is no deviation between the test environment and the online environment, the accuracy of the test results can be improved.

In a possible implementation manner, as shown in FIG. 1 , before the above step S13, it may further include: step S14, copying the historical data in the online environment of the system under test, and saving the copied historical data into the storage module;

After the above step S13, the method may further include: step S15, storing the data generated in the process of processing the stress test data by the system under test into the storage module.

In the above content, online data may refer to user requests, or user traffic; historical data may refer to data generated by the system under test in the process of processing online data.

The above-mentioned storage module may be set independently, and the storage module is relatively independent from the existing online storage. Wherein, the existing online memory is used to store the data generated in the process of processing the online data by the system under test (that is, the data generated when the online service is provided), and the storage module independently provided in the embodiment of the present application is used for Separately store the data generated by the system under test in the process of processing the stress test data (that is, the data generated during the test). Through this setting method, the data generated during the testing process can be isolated from the data generated during the online service provision, so as to avoid the impact of the testing process on the online service.

FIG. 2 schematically shows a schematic structural diagram of a stress testing system according to an embodiment of the present invention. In FIG. 2 , the solid line represents the data and devices involved when the system under test provides online services, and the dotted line represents the data and devices involved when the system under test is subjected to the stress test. It should be emphasized that while the system under test is being stress tested, it is also providing online services normally. The system under test in FIG. 2 is a system under test in an online environment, and can be deployed in a distributed service framework (DFS, Distributed Service Framework).

As shown in Figure 2, the contents related to online services include: transmitting online data to the online environment of the system under test, saving the data generated when the system under test provides online services in the online storage; In the case of external services, the interface of the real external service system is called, and the real external service system provides external services for the system under test.

As shown in Figure 2, the content involved in the stress test includes: transmitting the stress test data to the online environment of the system under test, and saving the data generated by the system under test in the process of processing the stress test data in an independently set storage module; When the system under test needs to rely on external services when processing stress test data, simulate the return value of the external service and provide the return value to the online environment of the system under test. The external service can be simulated by an independently set virtual external service module to avoid calling the real external service system. Since the stress test data is not the real user request data, if a real external service system provides services to the stress test data, it will be a waste of the resources of the external service system. Therefore, the embodiment of the present application adopts the method of simulating the return value of the external service to avoid waste or unnecessary pressure on the external service system; and, because the real external service system is not used, it is avoided that the external service system cannot provide services normally. This adversely affects the accuracy of the stress test. In addition, in this embodiment of the present application, a monitoring module may be set to monitor at least one performance index of the system under test; when the performance index exceeds a preset condition, stop sending stress test data to the online environment of the system under test, That is, the stress test is stopped.

The above outlines the functions of the various modules used for stress testing, as well as the data generation, transmission, and storage mechanisms. A detailed description is given below with reference to the accompanying drawings.

In a possible implementation manner, the above step S12 includes: performing at least one operation of copying and rewriting on online data to obtain stress test data.

Among them, copying may refer to: when the amount of online data parsed from the log is insufficient, the existing online data is copied multiple times, and the sensitive data in it is replaced, such as user identification (ID) and other data.

The rewriting may include: performing at least one operation of complementing, modifying, and replacing a predetermined field in the online data. Specifically, when the coverage scenarios of the online data parsed from the log are not comprehensive enough, the fields corresponding to the uncovered scenarios are completed, modified or replaced.

In some cases, different types of online data correspond to different scenarios and need to be processed by different processing logics of the system. Correspondingly, if a certain processing logic of the system under test needs to be tested, the corresponding type of stress test data needs to be used to trigger the processing logic. In order to obtain a sufficient amount of stress test data for processing specific processing logic, at least the following three methods may be adopted in this embodiment of the present application:

The first is to parse a sufficient amount of online data corresponding to the processing logic for a certain processing logic; replace the parsed online data with sensitive words to obtain a sufficient amount of stress test data. For example, for processing logic A, if 1 million pieces of corresponding stress test data are needed, parse 1 million pieces of online data corresponding to processing logic A; then replace the parsed online data with sensitive words to get 1 million pieces of data Process the stress test data corresponding to logic A.

Second, for a certain processing logic, parse a certain amount of online data corresponding to the processing logic; copy the parsed online data, replace sensitive words and rewrite fields to obtain a sufficient amount of stress test data. For example, for processing logic A, if 1 million pieces of corresponding stress test data are required, 10,000 pieces of online data corresponding to processing logic A can be parsed. Fields (such as fields carrying IP addresses, user names, etc.) are rewritten to obtain 1 million pieces of stress test data corresponding to processing logic A. Field rewriting can avoid field conflicts in different stress test data caused by replication.

The third is to parse a sufficient amount of other types of online data for a certain processing logic; rewrite the online data obtained by the analysis to generate a sufficient amount of stress test data that can trigger the processing logic. For example, it is assumed that in a real online environment, the probability of occurrence of online data of type X is small, the probability of occurrence of online data of type Y is relatively large, and the difference between online data of type X and online data of type Y is not large, And there are rules to follow. In order to test the processing logic corresponding to the X-type online data, you can parse a sufficient amount of Y-type online data; rewrite the specific fields of the parsed Y-type online data to obtain a sufficient amount of X-type stress test data.

Among the above three methods, the latter two use the rewrite operation, so as to realize the transformation of the online data, and obtain the stress test data for triggering the specific processing logic. These two methods have a better effect on some online data with a small probability of occurrence, because there is no need to parse all the data required for the stress test from the massive online data, which can reduce the process of acquiring and parsing the online data. pressure.

When rewriting is performed, the fields available for rewriting in the online data include: data header (header), data body (body), parameters (parameters), path (path) and the like. For example, the path field is specifically a Uniform Resource Locator (URL, Uniform Resource Locator); when rewriting, the URL of the online data can be generated according to a predetermined rewriting rule or mapping relationship to generate a new URL; the new URL can be used as pressure The path field of the test data. Other fields can be rewritten in the same or the same way as the path field, and will not be repeated here.

In order to enable the system under test to distinguish the online data from the stress test data, in the above step S13, a mark may be added to the stress test data sent to the system under test in this embodiment of the present application. FIG. 3 schematically shows an implementation flow chart of step S13 in the stress testing method according to an embodiment of the present invention, including:

S131: Include stress test data in the request, and add a stress test tag field to the request;

S132: Send the request to the online environment of the system under test.

With the above settings, after receiving a request, the system under test can distinguish which requests contain real online data and which requests contain stress test data for stress testing according to whether the request contains the stress test tag field. For the stress test data, the system under test stores the data generated during the processing in the above-mentioned separately set storage module.

In addition, in the above request, you can also configure test-related parameters such as the number of concurrency and the duration of the stress test. The role and reason of configuration include at least the following:

First, the number of concurrency can simulate the number of users online at the same time; by configuring different numbers of concurrency, stress tests of different intensities can be implemented, such as simulating stress tests during ordinary hours or simulating stress tests during peak hours.

Second, in some cases, due to the short duration of the system under test processing the request, the short processing time is not enough to fully reflect the operating status of the system under test server. In this case, you can set up a loop to process the request, and configure the stress test duration in the request. When the system under test receives a request, it cyclically processes the request within the duration of the stress measurement; when the duration of the stress measurement expires, it stops processing the request.

During the test, the above monitoring modules can be used to monitor the performance indicators of the servers related to each module of the system under test in real time. The specific performance indicators include but are not limited to: CPU usage, memory usage, hard disk input/output (IO, Input/Output), Network IO, interface response time, interface error rate, etc. When the performance index exceeds the preset condition, the pressure test of the system under test can be stopped to ensure that the response of the system under test to normal flow is not affected. The aforementioned preset condition may be set as a specific threshold, and the specific threshold is related to factors such as the importance to the system under test, the importance of the test period, and the like. The specific value of the specific threshold can be adjusted according to the actual situation during the stress test. For example, for a system under test, set the CPU usage threshold of the M period to 80%, and set the CPU usage threshold of the N period to 90%; relatively speaking, the M period is more important than the N period, so The CPU usage threshold setting for the M period is more stringent. During the stress test, monitor the CPU usage of the relevant servers of the system under test in real time. If the CPU usage is greater than 80% and it is currently in the M period, stop the stress test. The foregoing description is given by taking the CPU usage as an example. In actual monitoring, multiple performance indicators can be monitored at the same time, and when one or more performance indicators exceed a certain threshold, the stress test is stopped.

In a possible implementation manner, the above-mentioned independently set storage modules may include databases, caches, queues, logs, files, etc., to isolate the data generated during the stress test process from the data generated during the actual online service process. The server resources required by the above-mentioned storage module can be temporarily applied for, and after the stress test is completed, the data in the storage module can be deleted, and the server resources occupied by the storage module can be returned. Since the data generated during the stress test is stored separately, the cleaning logic for these data is also simple and clear.

When a stress test is performed in this embodiment of the present application, the processing of the stress test data does not affect the processing of other service models such as statistics and algorithm models.

From the above, it can be seen that the embodiment of the present application directly performs the stress test in the online environment, which can ensure that the stress test results are authentic and effective, and there is no need to build an additional test environment or high simulation environment consistent with the online environment, so server resources can be saved. Because a separately set storage module is used to store the data generated during the stress test, the impact on online services is avoided, and it is convenient for subsequent data deletion and server resource release.
