Hi Thomas. While I appreciate your response, I needed to share that at the time you commented, I had a copy paste error and wasn’t showing the actual solution in the final part of the article. So if you get the chance, you can see how the never type is used and how it helps me to not have to write a test at all.

I think it’s much nicer to not have to write a test for this kind of thing.

That being said, I’m thankful that there are people out there like yourself who want to write automated tests at all. Me too! Let’s keep spreading the test-writing love. :)

To put it in another way:
Write tests to observe changing behaviour of your application.
If your code has to change due to an error, write a test covering that changing behaviour.

Do not try to cover each and every cornercase.
