This work aims at generating all possible patterns of test cases for the given use case. Given a use case, generate all possible test cases that are mandatory for the given use case is actually the problem statement. For a particular use case, there can be hundreds and thousands of test cases. It can be even one to ten. This depends upon the programmer or developer who actually analyzes the use case while developing. Thus a programmer may miss some test cases that are mandatory and other could write unnecessary test case that has nothing to do with the use case. Thus this project aims at generating those test cases which are mandatory for the given use case and ensure that there cannot be more test cases than the generated one. The initial phase of the project involves Natural Language Processing and the later phases involve our own algorithm for generating these test case.
