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.
Functional testing is concerned only with the functional requirements of a system or subsystem and covers how well (if at all) the system executes its functions.These include any user commands, data manipulation, searches and business processes, user screens, and integrations.or example, in functional testing it might be revealed that the function of inputting data into a set of cells in a database works, however, usability testing (a part of Non Functional Testing) reveals that saving a version of the document requires 2 minutes, which will (or should) be judged as too long to wait.
