You should not test the implementation but the behavior
You test like the end user
For instance, imagine a login screen with email and password inputs and a submit button
The test should input the email and the password, then click in the submit button.

You already know that you will never be done learning. But most people "learn in private", and lurk. They consume content without creating any themselves. Again, that's fine, but we're here to talk about being in the top quintile. What you do here is to have a habit of creating learning exhaust. Write blogs and tutorials and cheatsheets.
