Python Test

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: Links: Too much of a good thing: the trade-off we make with testsLoad testing is hard, and the tools are... not great.

If you've ever thought about starting a podcast or a SaaS project, you'll want to listen to this episode. Justin is one of the people who motivated me to get started podcasting. He's also running a successful SaaS company, transistor.fm, which hosts this podcast. Topics: BTW. This episode was recorded last summer before I switched to transistor.fm. I'm now on Transistor for most of a year now, and I love it.

Charlie Marsh and team are using Rust to make Python tooling faster. Since uv is the newest tool, there's quite a bit of the discussion diving into uv. Links: ruffAstraluv Sponsored by PyCharm Pro jetbrains.com/pycharmpythontest.com/pycharmThe Complete pytest Course courses.pythontest.com

Software engineers that move into leadership roles have a struggle between learning leadership skills, maintaining technical skills, and learning new leadership and technical skills. Matt Makai went from individual contributor to developer relations to leadership in devrel. We discuss how to stay technical, as well as dive into some results of his studies in how companies use developer relationship channels.

If you haven't tried running automated tests, especially with pytest, in VS Code recently, you should take another look. The Python for VS Code interface for testing, especially for pytest, has changed recently. On this episode we discuss the change with the software engineer working on the pytest changes, Eleanor Boyd, and the product manager, Courtney Webster.

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.

In 2002, Kent Beck released a book called "Test Driven Development by Example". In December of 2023, Kent wrote an article called "Canon TDD". With Kent's permission, this episode contains the full content of the article. Brian's commentary is saved for a followup episode.

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: Plugins discussed: Sponsored by PyCharm Pro jetbrains.com/pycharmpythontest.com/pycharmThe Complete pytest Course courses.pythontest.com

Why on earth would you want to write a test with no assert statements? After all, aren't assert statements how you decide wether a test passes or fails? In this episode, we walk through a handful of useful examples of test code without asserts. We also talk about how these types of tests are a great way to dip your toe into testing.

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: Test FirstUnit TestsAcceptance TestsTest-Driven Development (wikipedia)

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:

Open Source is important to Intel and has been for a very long time. Joe Curley, vice president and general manager of software products and ecosystem, and Arun Gupta, vice president and general manager for open ecosystems, join the show to discuss open source, OneAPI, and open ecosystems at Intel.

Hynek joins the show to discuss towncrier. At the top of the towncrier documentation, it says "towncrier is a utility to produce useful, summarized news files (also known as changelogs) for your project." Towncrier is used by "Twisted, pytest, pip, BuildBot, and attrs, among others." This is the last of 3 episodes focused on keeping a CHANGELOG. Episode 200 kicked off the series with keepachangelog.com and Olivier Lacan In 201 we had Ned Batchelder discussing scriv. Special Guest: Hynek Schlawack.

Last week we talked about the importance of keeping a changelog. This week we talk with Ned Batchelder about scriv, a tool to help maintain that changelog. Scriv "is a command-line tool for helping developers maintain useful changelogs. It manages a directory of changelog fragments. It aggregates them into entries in a CHANGELOG file." Links: nedbat/scriv: Changelog management tool

A changelog is a file which contains a curated, chronologically ordered list of notable changes for each version of a project. This episode is about what a changelog is, with an interview with Olivier Lacan, creator of keepachangelog.com. The next two episodes talk about some tools to help software project teams keep changelogs while avoiding merge conflicts. Special Guest: Olivier Lacan.

For a web side project to go from "working on desktop" to "live in the cloud", one decision that needs to be made is where to host everything. One option is Microsoft Azure. Lots of corporate sites use it. Is it right for side projects? Pamela Fox, a Cloud Advocate for Python at Microsoft, joins the show to help us with that question. Special Guest: Pamela Fox.
