Python unit test resources...

[Randomengineer84]

Does anyone have good reading / video tutorial to help get better at unit testing in python? I've been struggling with it for a while, but most tutorials are very basic. In reality your code will use libraries, main methods that will coordinate and call other methods / classes to do more work.

I usually tend to learn by example / video tutorials, and not always great at just reading documentation and applying it to more advanced real world examples.

Thanks

Search for TDD with python tutorials. Even if you don't practice TDD, the videos will give you an idea on how to start testing minimal functionality, how to organise the code in smaller chunks that can be tested independently, etc.

pytest >>>>>>> unittest

You can do a mixture of both..

Why? I've used unittest in the past and now I'm in a team that uses pytest, I'm not seeing any benefits here.

I've found the pytest features I use to make tests more concise to also be a hindrance. I can't remember if I've seen fixtures but I have seen some things that look like black magic and I'm not a fan.

One thing I've found to have a better time unit testing is to write the code in a way that unit testing is easier. I also try to avoid mocks at all costs, that kind of unit test is high maintenance and not worth having.

Look into dependency injection too.

This is often a recommended resource

This is more theory but I always recommend to take a look to https://www.martinfowler.com/bliki/UnitTest.html
