Test & Code - Python Testing & Development

Django has some built in ways to test your application. There's also pytest-django and other plugins that help with testing. Carlton Gibson and Will Vincent from the Django Chat Podcast join the show to discuss how to get started testing your Django application.Special Guests: Carlton Gibson and Will Vincent.Sponsored By: porkbun: A refreshingly different domain name registrar.

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 Approved :: MIT License", "Framework :: Pytest" ] Special Guest: Brett Cannon.Links: Classifiers · PyPI PEP 621 – Storing project metadata in pyproject.toml | peps.python.org Packaging Python Projects — Python Packaging User Guide — Configuring metadata PEP 639 – Improving License Clarity with Better Package Metadata | peps.python.org SPDX 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 awesome.

Anthony Sottile and Brian discuss changes that would be cool for pytest, even unrealistic changes. These are changes we'd make to pytest if we didn't ahve to care about backwards compatibilty.Anthony's list: The import system Multi-process support out of the box Async support Changes to the fixture system Extend the assert rewriting to make it modular Add matchers to assert mechanism Ban test class inheritance Brian's list:  Extend assert rewriting for custom rewriting, like check pytester matchers available for all tests Throw out nose and unittest compatibility plugins Throw out setup_module, teardown_module and other xunit style functions Remove a bunch of the hook functions Documentation improvement of remaining hook functions which include examples of how to use it Start running tests before collection is done Split collection and running into two processes Have the fixtures be able to know the result of the test during teardown Special Guest: Anthony Sottile.Links: anthonywritescode - YouTube anthonywri

I don't think it's too much of a stretch to say that software is part of most scientific research now. From astronomy, to neuroscience, to chemistry, to climate models.  If you work in research that hasn't been affected by software yet, just wait.But how good is that software? How much of common best practices in software development are making it to those writing software in the sciences?Patrick Mineault has written "The Good Research Code Handbook".  It's a website. It's concise.  And it will put you on the right path to writing better software. Even if you don't write science based software, and even if you already have a CS degree, there's some good information worth reading.Special Guest: Patrick Mineault.Links: The Good Research Code Handbook game-wrath-jam: A game jam game, theme: Wrath Robotron 2084 - Arcade - YouTube The Book of Why: The New Science of Cause and Effect 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

The first game I remember coding, or at least copying from a magazine, was in Basic. It was Lunar Lander. Learning to code a game is a way that a lot of people get started and excited about programming. Of course, I don't recommend Basic. Now we've got Python. And one of the game engines available for Python is PursuedPyBear, a project started by Piper Thunstrom. Piper joins us this episode and we talk about PursuedPyBear, learning to code, and learning CS concepts with game development. PursuedPyBear, ppb, is a game framework great for learning with, with goals of being fun, education friendly, an example of idiomatic Python, hardware library agnostic, and built on event driven and object oriented concepts.Special Guest: Piper Thunstrom.Links: PursuedPyBear | Unbearably Fun Game Development Piper's Blog Making Games With PPB - PyTexas Shooter Game by Piper Thunstrom shootergame on GitHub Briefcase— BeeWare game-blink: A tiny emergent behavior toy.

In Python, before dataclasses, we had attrs. Before attrs, it wasn't pretty.The story of attrs and dataclasses is actually intertwined.  They've built on each other. And in the middle of it all, Hynek.Hynek joins the show today to discuss some history of attrs and dataclasses, and some differences.If you ever need to create a custom class in Python, you should listen to this episode.Full TranscriptSpecial Guest: Hynek Schlawack.Links: attrs documentation History of attrs and introduction to attrs namespace cattrs: Complex custom class converters for attrs. — python-attrs PEP 557 – Data Classes PEP 681 – Data Class Transforms 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 awesome.

Being productive is obviously a good thing. Can we measure it? Should we measure it? There's been failed attempts, like lines of code, etc. in the past. Currently, there are new tools to measure productivity, like using git metrics.Nick Hodges joins the show to discuss the good and the bad of developer and team productivity, including how we can improve productivity.Special Guest: Nick Hodges.

Don't you just love technical interviews, with someone who just saw your resume or CV 5 minutes ago asking you to write some code on a whiteboard. Probably code that has nothing to do with anything you've done before or anything you will do at the company.No? Neither does Nathan Aschbacher.  So when he started building the team at his company, he decided to do things differently.Hiring is one of the essential processes for building a great team. However, it's a high noise, low signal process.Nathan Aschbacher has a relatively unorthodox tech hiring approach.  He's trying to make it very humane, with a better signal to noise ratio. Nathan is not intereseted in bizarre interview processes where the interviewer doesn't know anything about the interviewee beforehand, all people are asked the same questions, and people are asked to code on white boards.Instead, he states "if the goal is to try to figure out if the person can do the work with your team, and your trying to build the team that you are adding this per

We talk with Adam Johnson about his new book, "Boost Your Django DX". Developer experience includes tools and practices to make developers more effective and efficient, and just plain make software development more fun and satisfying.  One of the things I love about this book is that it's not just for Django devs.  I'd guess that about half the book is about topics that all Python developers would find useful, from virtual environments to linters to testing.  But of course, also tons of tips and tools for working with Django.Full TranscriptSpecial Guest: Adam Johnson.Links: “Boost Your Django DX” Released — Adam's announcement Boost Your Django DX — The book 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 awesome.

Lean TDD is an attempt to reconcile some conflicting aspects of Test Driven Development and Lean Software Development.I've mentioned Lean TDD on the podcast a few times and even tried to do a quick outline at the end of episode 162.This episode is a more complete outline, or at least a first draft.If you feel you've got a good understanding of TDD, and it's working awesome for you, that's great. Keep doing what you're doing. There are no problems.For me, the normal way TDD is taught just doesn't work. So I'm trying to come up with a spin on some old ideas to make it work for me. I'm hoping it works for you as well.I'm calling the new thing Lean TDD. It's inspired by decades of experience writing software and influence from dozens of sources, including Pragmatic Programmer, Lean Software Development, Test-Driven Development by Example, and many blog posts and wiki articles. The main highlights, however, come from the collision of ideas between Lean and TDD and how I've tried to resolve the seemingly opposing p
