Where the number of user concurrency refers to the number of user requests/transactions processed by the system at the same time, and TPS refers to the number of transaction requests processed by the system per second.
Based on the above description, fig. 2 illustrates an exemplary flow of a method for pressure testing according to an embodiment of the present invention, where the flow may be performed by a device for pressure testing, and the device may be located in or may be the testing device.
As shown in fig. 2, the process specifically includes:
step 201, collecting first service flows actually generated by a device to be tested in a plurality of preset time periods;
The method comprises the steps that a plurality of preset time periods of a device to be tested can be determined according to specific service conditions of the device to be tested, and then first service flow actually occurring by the device to be tested is collected in each preset time period, wherein the preset time period is understood to be a time period which can be 1s, 2s or 1min, and the time period is determined according to actual experience.
For example, according to the historical data of the traffic flow of the device to be tested, it may be determined that the traffic flow of the device to be tested in the 1 st to 3 rd s is a smaller floating trend, the traffic flow in the 3 rd to 20 th s is a linear increase, the traffic flow in the 21 st to 40 th s is suddenly decreased, and the traffic flow in the 21 st to 40 th s is exponentially increased, and then a preset period may be set in the 1 st to 40 th s, which is the 1 st, 2 nd, 3 rd, 20 th, 21 st, 40 th s, and further the traffic flow in the 1 st, 2 nd, 3 rd, 20 th, 21 st, 40 th s may be determined as shown in table 1.
TABLE 1
Step 202, determining second traffic for testing in each testing period according to the first traffic in the plurality of preset periods;
Determining a second service flow of each test period according to the acquired first service flows of the preset periods, wherein two adjacent preset periods in the preset periods can be continuous or discontinuous, such as the 1 st and 2 nd preset periods are adjacent and continuous, and the 3 rd and 20 th preset periods are adjacent and discontinuous in table 1; two adjacent test periods of the plurality of test periods are each continuous.
In specific implementation, whether two adjacent preset time periods in a plurality of preset time periods are continuous or not can be determined, for the two adjacent and continuous preset time periods, the two preset time periods can be corresponding to two test time periods, and the first service flow of each preset time period is respectively determined as the second service flow of each preset time period corresponding to the test time period; for two adjacent but discontinuous preset time periods, determining a plurality of test time periods according to the two preset time periods, and determining a second service flow of each test time period in the plurality of test time periods according to the first service flow of the two preset time periods.
As in table 1, if the two preset periods of 1s and 2s are adjacent and continuous, the 1 st and 2 nd s may be determined as two test periods, respectively, and the first traffic 50, 51 corresponding to the 1 st and 2 nd s (preset period) may be determined as the second traffic 50, 51 corresponding to the 1 st and 2 nd s (test period), respectively. The 3s and 20s preset time periods are adjacent but discontinuous, the 3s, 4s, 5s, 6s … … s, 19s and 20s can be respectively determined as test time periods according to the 3s and 20s, and the 3s, 4s, 5s, 6s … …, 19s and 20s second service flows are respectively determined according to the first service flows 51 and 200 respectively corresponding to the 3s and 20 s.
When determining the second traffic of each test period according to the first traffic of two preset periods, specifically, the trend rule of the historical traffic of the period between the two preset periods in the historical data of the device to be tested can be determined first, for example, the traffic between the two preset periods is linearly increased, exponentially increased, linearly decreased, and the like, so that the second traffic of each test period is determined according to the trend rule and the first traffic of the two preset periods.
When the trend rule of the historical traffic in the period between the two preset periods is linear change, the second traffic in each test period can be determined through the formula (1).
Wherein, formula (1) is:
Wherein B 1 is the first traffic flow of the previous preset period of the two preset periods, B 2 is the first traffic flow of the next preset period of the two preset periods, A 1 is the previous preset period of the two preset periods, A 2 is the next preset period of the two preset periods, A 1 +K is the Kth test period of the periods between the two preset periods, The second service flow of the test period A 1 +K;
Still referring to the above example, the second traffic of the test period 3s, that is, the first traffic of the preset period 3s, and the second traffic of the test period 20s, that is, the first traffic of the preset period 20 s; determining a second traffic flow of a test period between two preset periods according to a first traffic flow of the preset period 3s and a first traffic flow of the preset period 20s, wherein the test periods 4s, 5s and 6s … … and 19s are respectively the first, second, third, … … and 16 test periods between the 3s and 20s, for example, the second traffic flow of the test period 4s is calculated, and then Similarly, the second traffic corresponding to the 5 th, 6 th, … … th and 19 th test periods may be as shown in table 2.
TABLE 2
In the above example, 21s, 22s, 23s, 24s … …, 39s, and 40s may be further determined as test periods according to 21s and 40s, respectively, and second traffic flows of 21s, 22s, 23s, 24s … …, 39s, and 40s may be determined according to first traffic flows 105 and 300 corresponding to 21s and 40s, respectively. For example, the traffic flow corresponding to each test period that is finally generated is shown in table 3.
TABLE 3 Table 3
And 203, starting a thread for sending a test task to the device to be tested according to the second service flow of each test period, and performing pressure test on the device to be tested.
In the embodiment of the invention, the performance of the device to be tested can be tested in two ways, one is to test the performance of the device to be tested by adopting the user concurrency index, and the other is to test the performance of the device to be tested by adopting the TPS index.
Specifically, when the performance of the device to be tested is tested by using the user concurrency index, the second service flow is the user concurrency number, the number N of the started threads can be determined according to the maximum user concurrency number in the user concurrency numbers of each test period, wherein N is a positive integer, after the N threads are started, M threads corresponding to the user concurrency number of the test period can be called in the started N threads according to the user concurrency number of the test period, so that each of the M threads continuously sends test tasks to the device to be tested in the test period, M is a positive integer, and M is less than or equal to N. For example, if the maximum user concurrency number in the user concurrency numbers of each test period is determined to be 300, it may be determined that 300 threads are started, each thread may be marked with an index number, and when the actual service flow of the device to be tested is 50 user concurrency numbers in the 1 st s, the second service flow for testing is 50 user concurrency numbers, threads with index numbers of 0 to 49 may be started, and each thread is used for continuously sending test tasks to the device to be tested, so as to simulate that the device to be tested receives task requests sent by 50 users together in the 1 st test period.
In the actual use process, after the test device starts the threads, each started thread judges whether to send a test task to the device to be tested every 10ms, if so, the test task is sent to the device to be tested, otherwise, the test task can be judged again after being delayed for 10 ms.
When the performance of the device to be tested is tested by adopting TPS indexes, the second service flow is TPS, the number N of the starting threads can be determined according to the maximum TPS in TPS of each test period, wherein N is a positive integer, after the N threads are started, M threads corresponding to the TPS of the test period can be called in the started N threads according to the TPS of the test period, so that each thread in the M threads sends a preset number of test tasks to the device to be tested in the test period, wherein M is a positive integer, and M is less than or equal to N. For example, if it is determined that the maximum TPS in TPS of each test period is 1000, 200 threads may be started, each thread may be marked with an index number, and when the actual TPS of the device to be tested is 250 in the 1 st s, the second traffic flow for testing is 250TPS, threads with index numbers of 0 to 49 may be started, each thread is used for sending 5 test tasks to the device to be tested, 250 test tasks are sent in total, after the test device determines that 250 test tasks are sent to the device to be tested, sending test tasks to the device to be tested may be stopped, so that the device to be tested is simulated to receive 250 test tasks in the 1 st test period. Here, the number of test tasks sent by each of the M threads to the device under test may be the same or different, and is not limited herein.
In the above embodiment, by collecting the service flows actually generated by the device to be tested in a plurality of preset time periods, determining the service flows of the device to be tested for testing in each test time period, and using the determined service flows of each test time period for pressure testing the device to be tested, the service flows carried by the device to be tested in a real scene can be simulated, so that the performance of the device to be tested in the real scene can be accurately evaluated.
