JUnit is an open source framework designed for the purpose of writing and running tests in the Java programming language. It's a regression-testing framework that developers can use to write unit tests to check that another code unit works as expected. The Rose India tutorial course of JUnit helps to code and test any time when you make any changes in your code during the development. It ensures that modifications in the code will not break your system without your knowledge. JUnit has been ported to other languages, including PHP (PHPUnit), C# (NUnit), Python (PyUnit), Fortran (fUnit), Perl (Test::Class and Test::Unit), C++ (CPPUnit) and JavaScript (JSUnit).This family of unit testing frameworks is referred to collectively as xUnit.
