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.
Alpha testing is the last testing done by test teams at development site after the acceptance testing and before releasing the software for beta test. Alpha testing can also be done by potential users or customers of the application. But still this is a form of in-house acceptance testing.
