211: Stamp out test dependencies with pytest plugins
We want to be able to run tests in a suite, and debug them in isolation, and have the behavior be the same. If the behavior is different in isolation vs in a suite, it's a nightmare to debug. In this episode, we'll talk about: Causes of dependence Testing for dependencies using plugins Debugging test dependencies Plugins discussed: pytest-randomly pytest-reverse pytest-random-order

236: Git Tips for Testing - Adam Johnson
In this episode, host Brian Okken and guest Adam Johnson explore essential Git features, highlighted by Adam's updated book, "Boost Your Git DX." Key topics include "cherry picking" for selective commits "git stash" for managing in-progress work "git diff", and specifically its `--name-only` flag, which provides a streamlined method for developers to identify which files have changed, which can be used to determine which tests need to be run "git bisect" for efficiently pinpointing bugs. This conversation offers valuable strategies for developers at any skill level to enhance their Git…

234: pytest-metadata - provides access to test session metadata
pytest-metadata is described as a plugin for pytest that provides access to test session metadata. That is such a humble description for such a massively useful plugin. If you're already using pytest-html, you have pytest-metadata already installed, as pytest-metadata is one of the dependencies for pytest-html. However, pytest-metadata is very useful even on its own. Links: pytest-metadata - The plugin we're talking about in this episode pytest-base-url - Adds the base URL to the metadata. pytest-html - Displays the metadata at the start of each report.

233: pytest-check - allow multiple failures per test
pytest-check is a pytest plugin that allows multiple failures per test. Normally, a test function will fail and stop running with the first failed assert. That's totally fine for tons of kinds of software tests. However, there are times where you'd like to check more than one thing, and you'd really like to know the results of each check, even if one of them fails. pytest-check allows multiple failed "checks" per test function, so you can see the whole picture of what's going wrong.

232: The role of AI in software testing - Anthony Shaw
AI is helping people write code. Tests are one of those things that some people don't like to write. Can AI play a role in creating automated software tests? Well, yes. But it's a nuanced yes. Anthony Shaw comes on the show to discuss the topic and try to get AI to write some test for my very own cards project. We discuss: The promise of AI writing your tests for you Downsides to not writing tests yourself Bad ways to generate tests Good ways to ask AI for help in writing tests Tricks to get better results while using copilot and other AI tools Links: The cards project A video version of…
