Forget the false assumption that bugs are inevitable in software. Discover most of the faults with our new test design techniques!

Two brand new techniques are introduced here. Both action-state testing and general predicate testing are proved to be efficient, by which you can find almost all the bugs in your code, where the code represents any stateful application or represents any business logic with boundaries.

Action-state testing is a unified technique of state transition testing and use case testing. It has all the advantages of both techniques and eliminates their shortcomings. Not only does your code quality improve but the total SDLC cost decreases as well.

General predicate testing (GPT) is a generalization of boundary value analysis, by which all the erroneously coded or tested predicate bugs can be revealed with the help of a minimised test set. The minimisation process can fully be automated.
