Module testing is the testing of complete code objects as produced by the compiler when built from source. A library may be composed of a single compiled object or several compiled objects. There is only a slight difference between unit testing and module testing.
System Integration Testing (SIT), in the context of software systems and software engineering, is a testing process that exercises a software system's coexistence with others.ntegration testing is completed first, not the system testing. In other words, upon completion of integration testing, system testing is started, and not vice versa. For integration testing, test cases are developed with the express purpose of exercising the interfaces between the components.
