1. Myers proposed a comprehensive strategy using various test methods:
1) you must use boundary value analysis, in any case, experience has shown that this method to design test cases found bugs strongest. [Source: Vince Testing Technology Research Center http://blog.csdn.net/vincetest ]
2) add some test cases equivalence partitioning method when necessary.
3) with the wrong reckoning and then an additional test cases.
4) control program logic, logic checks have been designed to test the extent of coverage, if coverage criteria did not meet the requirements, it should be sufficient to add test.
5) combinations if the functions of the program description contained in the input conditions, the selection can cause a start method of FIG.
2. The test case design steps [Source: Vince Testing Technology Research Center http://blog.csdn.net/vincetest ]
1) constructed according to the design specifications of the basic function of the test results;
2) the boundary value test;
3) state transition test;
4) error guessing test cases;
5) abnormal test case; [Source: Vince Testing Technology Research Center http://blog.csdn.net/vincetest ]
6) Performance test;
7) pressure test cases.
3. Optimization of test cases
1) using the test case design . 8 method of continuously combined decomposition and test cases;
2) genetic algorithm evolutionary theory test;
3) When testing the use of divergent thinking test structure.
