Description
Technical field
The present invention relates to computer software performance test field, particularly relate to a kind of software performance testing method and device.
Background technology
At present performance test is carried out to a software: common way writes performance test code (script), and performance test code is exactly in fact the client-side program automatically performed, can referred to as performance test client.Then setting up performance test process, in the application service of in-process concurrent running multiple performance test client-access, carrying out the object of performance test like this with regard to reaching the working pressure simulating multiple client.The rise of internet, applications, proposes increasing challenge to software performance test.Mass users online use is simultaneously the notable feature of internet, applications, therefore, software performance test based on internet, applications requires that can ensure a large amount of performance test clients in test scene runs simultaneously, can reach the object of abundant real simulation like this.
Existing performance test methods is all that the process of its method of testing is as follows in use a certain performance testing tool when most:
The generation of test code: test code is got by 2 kinds of modes, the 1st kind is the behavior of recording test client, then does parameterized treatment; 2nd kind be directly develop this category code for; Described test code only simulates the behavior of a client; All codes are all designed to order in a thread and perform.
Test execution: Software Testing Tool provides test process, in-processly provides an exclusive thread for each test client.If control multiple stage test machine (m platform), often platform test machine to start multiple test process (n), each test process comprises multiple test thread (t), and like this, the client number simultaneously participating in testing is m*n*t.
Consider from the angle of Software for Design performance, the system resources such as test machine number of threads, cpu utilization rate, internal memory will soon become the bottleneck of performance test with the increase of test pressure.So existing method of testing can only test the scene of some low-pressures, if test Internet service, the performance issue of test process test can be caused to carry out or the cost such as time, fund, personnel very high.And do not consider the demand that test client communicates mutually in the design process, in certain test moment, such as performance test customer end A requires that performance test customer end B completes certain function or changes certain attribute, this cannot accomplish, because certain performance test client is closed in design, test scene is caused to design upper underaction.
In sum, of the prior art, software performance testing method can not realize test client and directly communicate, and is subject to the restriction of system resource when magnanimity test client is tested simultaneously.
