Running Specific Tests

To run a single test case or test suite, you can use the only method as describe.only() or it.only(). And inversely, you can skip tests by using describe.skip() or it.skip(). The usage is well documented in mocha exclusive tests and mocha inclusive tests.

Another approach to specify tests without modifying the code is to run npm test with option -g. You can apply a filer on the names of tests like npm test -- -g 'some test'. Please note mocha arguments must be separated from npm arguments using --. More usage and examples can be found in page mocha - option grep.
