I remember using test methods a lot when refactoring code as well. You did a great video about that and I was nodding my head in agreement the whole time. We put running of the test suite as part of the build/ make process and some of the team were always 'surprised' when it failed. My answer was always, "And THAT is why we put it in the build file"

I've been dealing with a codebase full of SQL queries (both raw and using an ORM), and it's been so hard to refactor. Long functions full with logic mixed with queries. It would be great if you could discuss how to approach these cases, Arjan. It's specially hard to test first because you need to generate / mock lots of entities

I used to run away form testing but after trying it, i found it to be really interesting and fun and a lot more useful- it’s like writing JavaScript with typescript more writing but lesser debugging

Arjan, what do you think about mutation test? Maybe a video explaining how can contribute to have more quality in your unit test.

[thomasbrothaler]

Which package do you prefer? Pytest vs Unittest? I saw you using pytest, what is the reason for that?

[TerizianS]

How do unit tests work for Data Scientists or work in AI such as deep learning?

[thomasroberts]

I'd like to see a video on dealing with tests that make external call, i.e. to a rest API
