I just love it when the keyboard is abused. Oh wait, where's part 2?

Nice video man.

Also the command jest./js/index is not working as the git bash shows jest command not found though the Jest is installed properly. So can you please let me know what should be done.

very nice. Thank you so much.

But this is not a unit tests. In unit tests, you should mock all other methods except for the one you are testing right now.


For instance, when you are writing tests for validateConfirmPassword you should mock a validatePassword method to return a predefined value and then set an expectation that a setValidationRes will be called with certain arguments.


Otherwise, as you mention is the beginning of the video this gonna be an integration test.

Cool! Can you tell me how to integrate jquery with it?

Good, waiting for more.
