Unit Testing is the first level of testing in the waterfall methodology, performed with the purpose of validating a certain feature, function or module of the software app.
Integration Testing is the next level of testing in the software development after unit testing, used for determining how two units work together and for exposing flaws in the interaction between them.
Following unit and integration testing, system testing is a complementary type of software testing strategy, designed for conducting a complete evaluation of more units integrated together with the requirements of the app.
User Acceptance Testing
User Acceptance Testing refers to the last testing phase in the waterfall methodology, during which the app is tested in real situations by real users or the client himself before its release.
