98: pytest-testmon - selects tests affected by changed files and methods - Tibor Arpas

1/21/2020
pytest-testmon is a pytest plugin which selects and executes only tests you need to run. It does this by collecting dependencies between tests and all executed code (internally using Coverage.py) and comparing the dependencies against changes. testmon updates its database on each test execution, so it works independently of version control. In this episode, I talk with testmon creator Tibor Arpas about testmon, about it's use and how it works. Special Guest: Tibor Arpas.

95: Data Science Pipeline Testing with Great Expectations - Abe Gong

11/30/2019
Data science and machine learning are affecting more of our lives every day. Decisions based on data science and machine learning are heavily dependent on the quality of the data, and the quality of the data pipeline. Some of the software in the pipeline can be tested to some extent with traditional testing tools, like pytest. But what about the data? The data entering the pipeline, and at various stages along the pipeline, should be validated. That's where pipeline tests come in. Pipeline...

87: Paths to Parametrization - from one test to many

9/11/2019
There's a cool feature of pytest called parametrization. It's totally one of the superpowers of pytest. It's actually a handful of features, and there are a few ways to approach it. Parametrization is the ability to take one test, and send lots of different input datasets into the code under test, and maybe even have different output checks, all within the same test that you developed in the simple test case. Super powerful, but something since there's a few approaches to it, a tad tricky to...
