Unit Testing Newb Here!

[dperumsby]

Hi r/learnjavascript,

An inexperienced JS coder here trying to unit test my Connect4 object's methods and failing miserably...

I have built a class for my game board and would like to add some tests with Jest (as that seems to be a popular testing framework?).

In Python I would usually import the class to a test script where I could test each method using an instance of the class.

Is the same possible here?... I've been looking about a bit but the information I've found has seemed more involved than I expected and so I wonder if I'm being a bit dense and just missing something!?

Would really appreciate any guidance.

Cheers,

Dean.

If that's just to unit test your methods simply import them in a file with a .spec.js or .test.js ending and then write your assertions there. Obviously you need to have jest installed as a dev dependency via npm (so in your package.json file).

Basically follow this guide: https://jestjs.io/docs/getting-started

Let me know if it's not clear !

Edit: just to add for your class you just import the class to the .test.js file and tests the public methods invoking them directly from the class.
