QUnit - Only Test

Sometimes it happens that our code is not ready and the test case written to test that method/code fails, if run. QUnit.only helps in this regards. A test method written using only method will be executed while other tests will not run. If more than one only methods are specified, then only the first one will execute. Let's see only method in action.
