State the strategies of Software testing
Two testing strategies are present.
i) Code Testing:Code testing strategy examines the logic of the system. In this, analyst develops test cases for each instruction in code. All paths in program are tested. This test doesn't guarantee against software failures. Additionally, it doesn't signify whether code is according to requirements or not.
ii) Specification Testing: In this, testing with specific cases is performed. Test cases are developed for every combination or condition of conditions and submitted for processing.
The purpose of testing is to design test cases which systematically uncover different classes of errors and do so with minimum amount of effort andtime. Testing can't show the absence of errors. It can only find presence of errors. Test case design is as challenging as software development. Yet, though effective the design is, it can't remove 100% errors. Even, best quality software aren't 100 % error free. Reliability of software is closely dependent on testing.
