What is the use of Mocha?
Mocha is a JavaScript test framework that runs test cases in the browser and on Node JS. By running serially, Mocha JavaScript testing ensures flexibility and precise reporting by mapping uncaught exceptions to the proper test cases.
Mocha provides a systematic technique to writing code for thoroughly testing programmes, separating them into test suites and test case modules for execution and creating a test report after the run by mapping failures to associated test cases.
