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.
Automation testing is an Automatic technique where the tester writes scripts by own and uses suitable software to test the software. It is basically an automation process of a manual process. Like regression testing, Automation testing also used to test the application from load, performance and stress point of view.In other word, Automation testing uses automation tools to write and execute test cases, no manual involvement is required while executing an automated test suite.utomation testing is a best way to fulfill most of the testing goals with effective resources and time. But be careful before purchasing the automation tool that fulfills the requirement of the application because no any tool can fulfill 100% requirement.
