In front of multi-threaded concurrent test requirements, Junit and TestNG these two simple unit test framework has been used to compare, but users generally prefer to the test framework that configuration is simple, flexible, and easy to operate and satisfied the test requirements. This thesis has made an experimental comparison of Junit and TestNG on multi-threaded concurrent test methods, to verify the two frameworks implementation for multithreaded concurrent test, and provides the basis for the user to select the tool in the actual test scenario for users.
