    When working in mocha, oftenly you don't want to run all the test cases. Mocha provides you the feature to specify which exactly you want to run.

    Running a single test file

    Using mocha-cli you can easily run a single. This can be accomplished with the grep option when running the mocha command.

    Syntax:

    $ mocha --grep users.js
    
    or
    
    $ mocha test users.js


    Running a single test

    If you want to run a single test you can use the .only() method:-

    it.only(function () {
      // this test will run
    });
    it(function () {
      // this test will be skipped
    });

    Skipping a test

    If you need to skip a test case, you can use the .skip() method like as follows:

    it.skip(function () {
      // this test will be skipped
    });
    it(function () {
      // this test will be executed
    });
