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.
Integration testing, also known as integration and testing (I&T), is a software development process which program units are combined and tested as groups in multiple ways.In this context, a unit is defined as the smallest testable part of an application.here are two major ways of carrying out an integration test, called the bottom-up method and the top-down method. Bottom-up integration testing begins with unit testing, followed by tests of of progressively higher-level combinations of units called modules or builds.
