Nicole is a software engineer and writer, and recently wrote about the trade-offs we make when deciding which tests to write and how much testing is enough. We talk about: Balancing schedule vs testingHow much testing is the right about of testingShould code coverage be measured and trackedGood refactoring can reduce code coverageIs it worth testing error conditions?Are rare error codes ok to just monitor?API drift and autospecMitigating riskDeciding what to test and what not to testFocus...

Charlie Marsh and team are using Rust to make Python tooling faster. Ruff can take the place of Flake8, isort, and Black, and so much more.uv can take the place of pip, pip-tools, and virtualenvAstral is Charlie's venture backed company, and what they have with `ruff` and `uv` is just the start.Since uv is the newest tool, there's quite a bit of the discussion diving into uv.

If a test fails in a test suite, I'm going to want to re-run the test. I may even want to re-run a test, or a subset of the suite, a bunch of times.  There are a few pytest plugins that help with this: pytest-repeatpytest-rerunfailurespytest-flakefinderpytest-instafailWe talk about each of these in this episode.

TDD (Test Driven Development) started from Test First Programming, and has been around at least since the 90's. However, software tools and available CI systems have changed quite a bit since then. Maybe it's time to re-examine the assumptions, practices, processes, and principles of TDD.  At least in the context of my software engineering career, modifications to TDD, at least the version of TDD as it's frequently taught, have been necessary. This is the start of a series focused on...

On a recent episode of PythonBytes, I suggested it's hard to come up with good examples for pytest autouse fixtures, as there aren't very many good reasons to use them.  James Falcon was kind enough to reach out and correct me.  In this episode, we describe: what fixtures are what autouse fixtures are great reasons to use them If you like Test & Code, I think you'll also like Python People Python People is a new podcast about getting to know the people who make Python and our community...

Classifiers are one bit of Python project metadata that predates PyPI. Classifiers are weird. They were around in setuptools days, and are still here with pyproject.toml. What are they? Why do we need them? Do we need them? Which classifiers should I include? Why are they called "trove classifiers" in the Python docs Brett Cannon joins the show to discuss these wacky bits of metadata. Here's an example, from pytest-crayons: [project] ... classifiers = [ "License :: OSI...
