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 a software is carried out performance test: common way is to write performance test code (script), and the performance test code is exactly in fact the client-side program that automatically performs, can be referred to as the performance test client.Then set up the performance test process, in the application service of a plurality of performance test client-access of in-process concurrent running, the purpose of having carried out performance test with regard to having reached the working pressure of simulating a plurality of clients like this.The rise of internet, applications has proposed increasing challenge to software performance test.Mass users simultaneously online the use is the notable feature of internet, applications, therefore, the software performance test that Internet-based is used requires can to ensure a large amount of performance test clients in the test scene and moves simultaneously, can reach like this purpose of abundant real simulation.
Existing performance test methods all is to use a certain performance testing tool in most situations, and the process of its method of testing is as follows:
The generation of test code: test code is got by 2 kinds of modes, and the 1st kind is the behavior of recording test client, then does parametrization and processes; The 2nd kind be directly develop this category code for; Described test code is only simulated the behavior of a client; All codes all are designed to order execution in a thread.
Test execution: Software Testing Tool provides test process, in-processly provides a thread of monopolizing for each test client.If control many test machines (m platform), every test machine starts a plurality of test processes (n), each test process comprises a plurality of test threads (t), and like this, the client number that participates in simultaneously test 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 be tested the scene of some low-pressures, if the test Internet service, the performance issue of test process can cause test can't carry out or the costs such as time, fund, personnel very high.And in design process, do not consider the mutually demand of communication of test client, constantly require the performance test customer end B to finish certain function or change certain attribute in certain test such as the performance test customer end A, this can't accomplish, because certain performance test client is sealed in design, cause the upper underaction of test scene design.
In sum, of the prior art, software performance testing method can not realize that test client directly communicates by letter, and is subject to the restriction of system resource when the magnanimity test client is tested simultaneously.
