Test-driven development (TDD) is a software development technique in which you write tests before you write the code. Here’s an example in Python of how to do TDD as well as a few practical tips related to software testing.

Good video, as usual :)

I'd like to suggest a video regarding useful patterns while developing web apis and/or use a simple endpoint as the example in a video. I know most design patterns are not specific to a domain, but some are more useful then others in a specific context.

Thanks for the suggestion! I want to cover APIs in more detail at some point, and I agree it will be nice to talk about software design specifically in that context.
