213: Repeating Tests

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-repeat pytest-rerunfailures pytest-flakefinder pytest-instafail We talk about each of these in this episode.

206: TDD in Context
Test and Code
by Brian Okken
3M ago
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 examining TDD and related lightweight practices and processes. Links from the show: From XP Test First ..read more
