Embodiment Construction

[0039] The test logic of the present invention will be described below by taking a test program that starts two test threads as an example.

[0040] figure 1 Shown is the test logic for two test threads applying the method described in the present invention. In the first test thread, the first API interface and the second API interface should be called, and in the second test thread, the third API interface and the fourth API interface should be called. Assuming that a concurrency conflict test needs to be performed on each API interface call, a synchronization application point is inserted before the above four calls to the API interface.

[0041] When each test thread executes to the synchronization application point, it will send a synchronization application to the test program. For example, after the test program accepts the synchronization application from the first test thread, it keeps the first test thread in a waiting state until it accepts the synchronization appl...

Abstract

A method for testing collision of multilinear program software includes inserting synchronous application point before application program interface to be tested and to be called in test logic, operating at least two test linear programs and issuing synchronous application when test linear program is operated up to said point, judging whether said synchronous application is accepted or not and continuously issuing said synchronous application if it is not, continuously executing all test linear program to carry out collision test of test linear program if it is when the other test linear programs are at waiting-state.

Description

technical field [0001] The invention relates to the field of software testing, in particular to a method for testing concurrency conflicts of multithreaded software. Background technique [0002] At present, a large number of application software adopt multi-thread technology, and such application programs can make better use of system resources. The main advantage of multi-threading technology is that it makes full use of the idle time slice of the CPU (Central Process Unit, central processing unit), and can use as little time as possible to respond to user requirements, so that the overall operating efficiency of the software is maximized. Improve, while enhancing the flexibility of the application software. [0003] However, multithreading technology also brings design and testing complexity while enhancing software functions. Since the realization of the API (Application Program Interface, application programming interface) function in the multi-threaded software reali...
