As noted in another post I made, I believe it would be a great help to learners to simply explain how they can read the source of tests and see more detailed output from them by using the following resources:
Viewing Glitch logs/console while running the tests.
Using something like Postman to be able to write similar tests and make assertions. Being able to run the actual tests locally would of course be better.
I still think the whole certification needs a lot of work, and you shouldn’t have to know how to do testing to this degree prior to completing the testing certification, but this will at least help people get through the current projects without the level of frustration I and many others seem to have experienced.
