step 103: determining the optimal resources required by each performance test stage according to the optimal TPS corresponding to each performance test stage; the optimal resources required by each performance test stage are used for carrying out actual performance tests.
Compared with the technical scheme that the resource needed by the performance test can be estimated only according to experience or historical data and the proportion of the resource is adjusted, the simulation estimation method of the resource needed by the performance test provided by the embodiment of the invention is inaccurate and unreasonable, and comprises the following steps: before the performance test, receiving a performance test simulation request of a user; simulating the performance test of each stage by given different required resources according to the performance test simulation request to obtain the number of Transactions Per Second (TPS) of each system corresponding to each performance test stage; determining the optimal resources required by each performance test stage according to the optimal TPS corresponding to each performance test stage; the optimal resources required by each performance test stage are used for carrying out actual performance tests, so that the resources required by each link of the performance tests can be quantitatively and reasonably estimated, the accuracy of the estimated resources is improved, and the performance tests are efficiently and stably carried out. This is described in detail below with reference to fig. 2 to 4.
The platform (device) for realizing the simulation estimation method of the resources required by the performance test provided by the embodiment of the invention can comprise three parts, wherein the first part simulates the request sent by a user, the second part simulates the resources and time consumed by each link, and the third part generates the waveform of TPS changing along with the time. The platform can set the frequency of initiating requests, the resources and time required by each link, so as to simulate the TPS performance of the system under different loads, different resources and response time. The simulation estimation method of the resources required by the performance test provided by the embodiment of the invention provides a measurable mode for estimating the processing capacity TPS of the resources and the system. The simulation estimation method of the resources required by the performance test comprises the following steps.
First, the above step 101 is described.
In particular, the receiving of the software performance test simulation request from the user may be implemented by a request initiating module (hereinafter, referred to as a receiving unit), which may simulate the request for initiating different stresses.
Next, the above step 102 is described.
In particular, the step 102 may be implemented by a process module (i.e., a simulation unit mentioned below), which is a process module requiring different resources and response times for simulation.
In an embodiment, simulating the performance test of each stage according to the performance test simulation request with different given required resources to obtain different system transaction number per second TPS for each performance test stage may include: and calling a preset processing thread according to the performance test simulation request and given different required resources, and completing the performance test of each stage according to the initial state, the processing state and the completion state to obtain different TPS corresponding to each performance test stage.
In one embodiment, as shown in FIG. 2, the results of the performance test at each stage are used as input data for the next stage.
In specific implementation, as shown in fig. 3, a state machine is introduced to determine each executed state, that is, to call a preset processing thread, and to complete the performance test of each stage according to the initial state, the processing state, and the completion state. FIG. 3 illustrates a process processing state machine, which implements calling a default processing thread to perform performance testing of each stage according to an initial state, a processing state, and a completion state.
In an embodiment, simulating the performance test of each stage according to the performance test simulation request with different given required resources to obtain different system transaction number per second TPS for each performance test stage may include: and simulating the performance test of each stage according to the performance test simulation request by given different loads, different required resources and response time to obtain different TPS corresponding to each performance test stage.
In the specific implementation, in the process of the simulation estimation, different required resources are considered, and different loads and response times are also considered, so that the accuracy of the determination of the TPS is further improved, and accordingly, according to the optimal TPS corresponding to the different required resources and the different loads and response times, in the subsequent step, the required resources corresponding to the optimal TPS, and the loads and the response times are the optimal resources, loads and response times required in the actual performance test.
Third, next, a preferred step 102' following the above step 102 is described.
In one embodiment, as shown in fig. 4, the method for estimating the simulation of the resources required for the performance test may further include step 102': each performance testing stage is shown graphically for a different TPS.
In specific implementation, different TPS corresponding to each performance test stage is displayed in a chart form, so that the optimal TPS is determined conveniently, and the most reasonable and optimal resources required by each performance test stage are determined more reasonably.
Fourth, next, the above step 103 is described.
In specific implementation, in this step 103, the optimal TPS is determined according to different TPS corresponding to different required resources, and then, the required resource corresponding to the optimal TPS is the optimal resource required in the actual performance test.
In practical implementation, the above steps 102' and 103 can be implemented by a result statistic module (as shown in fig. 2, i.e. the display unit and the estimation unit in fig. 6).
To facilitate an understanding of how the invention may be practiced, reference will now be made, by way of example, to fig. 2 and 3 in general.
1. A request initiating module: a request to initiate different pressures is simulated.
2. A process processing module: the simulation requires processing modules of different resources and response times.
3. A result counting module: and counting real-time TPS, and converting the result into a chart for displaying.
4. The request initiating module fills a request queue according to the set frequency of initiating requests; the process processing module continuously reads the request from the request queue, if the request is read, the processing thread is called to process the request, the processing process is switched according to three states of an initial state, a processing state and a completion state, when the request reaches the completion state, the process (link and performance test stage) is completed, the processing result is stored in the result queue and enters the next process processing module, the next process processing module also continuously reads the last result queue, and the read result is input into the next process processing module as the request; when all the process processing modules are finished, the request processing is finished, and the result counting module counts TPS results and displays the TPS results in a form of a table. Finally, the optimal resources required by each performance test stage are determined for carrying out actual performance tests.
The simulation estimation method for the resources required by the performance test provided by the embodiment of the invention realizes that:
1) request queues and message queues are designed to store requests and execution results.
2) A state machine is designed to simulate process processing, namely, a preset processing thread is called, and performance test of each stage is completed according to an initial state, a processing state and a completion state.
3) Multiple channels are designed to simulate multiple threads, given the different required resources, the performance test of each stage is simulated, and the response time is simulated by the execution time.
4) And the TPS variation trend is displayed by using a chart, and the method is intuitive.
In summary, the method for estimating the resource needed by the performance test according to the embodiment of the present invention can estimate the needed resource and the ratio of the resource at the initial stage of the performance test, so as to reasonably allocate the resource, and can estimate the theoretical TPS based on the existing resource.
