With some other fine people I organise an annual testing unconference in the Netherlands: TestCraftCamp.
The four-hour tester
Building an API testing framework
Full-day workshop in which you build an API testing framework from scratch using Python, pytest, and the requsts library. All materials can be found here. These also include examples of next steps and a single test implemented in using different Python libraries, such as tavern, robot and behave.
Session-tools (GitHub) is a small suite of note-taking tools for session-based test management (SBTM).
