What is the difference between software fault and software failure?
Software failure occurs when the software does not do what the user expects to see. Software fault, on the other hand, is a hidden programming error.A software fault becomes a software failure only when the exact computation conditions are met, and the faulty portion of the code is executed on the CPU. This can occur during normal usage. Or, when the software is ported to a different hardware platform. Or, when the software is ported to a different complier. Or, when the software gets extended. before creating test cases to ” break the system” , a few principles have to be observed: Testing should be based on user requirements. This is in order to uncover any defects that might cause the program or system to fail to meet the client’s requirements.Testing time and resources are limited. Avoid redundant tests.It is impossible to test everything. Exhaustive tests of all possible scenarios are impossible, simple because of the many different variables affecting the system and the number of
