How do you write tests for things that aren’t that easy to write tests for? That question is a possibly terrible summary of a question sent to me by a listener. And to help me start answering that question, I asked a friend of mine to help, Antony Shaw. Of course, different types of applications have different test strategies, so there’s not a universal answer. But I know some of you out there have experience and expertise around how to tackle this problem. Listen to the discussion Anthony and I have about it, and let me know if you have some techniques or tips to add.

David Heinemeier Hansson is the creator of Ruby on Rails, founder & CTO at Basecamp (formerly 37signals). He's a best selling author, public speaker, and even a Le Mans class winning racing driver. All of that, of course, is awesome. But that's not why I asked him on the show. In 2014, during a RailsConf keynote, he started a discussion about damage caused by TDD. This was followed by a few blog posts, and then a series of recorded hangouts with Martin Fowler and Kent Beck. This is what I wanted to talk with David about; this unconventional yet practical and intuitive view of how testing and development work together. It's a great discussion. I think you'll get a lot out of it.Special Guest: David Heinemeier Hansson.Sponsored By:PyCharm Professional: If you value your time, you owe it to yourself to try PyCharm.

After I had wrapped up the interview with Kelsey Hightower for episode 43, I asked him one last question. You see, I admire the his presentation style. So I asked him if he would share with me how he prepared for his presentations. His answer is so thoughtful and makes so much sense, I couldn't keep it to myself. I'm releasing this as a bonus mini-episode so that it's easy to refer back to the next time you or I have a chance to do a technical talk.Special Guest: Kelsey Hightower. ★ Support this podcast on Patreon ★

I first heard Kelsey speak during his 2017 PyCon keynote. He's an amazing speaker, and I knew right then I wanted to hear more about what he does and hear more of his story. We discuss testing, of course, but we take it further and discuss: tests for large systems, like kubernetes Testing in real world scenarios with all the configuration and everything Becoming a complete engineer by thinking about the end to end flow from the users perspective Learning from other roles, and the value of roles to allow focus and expertise We even get into Chaos Engineering and testing live systems.

This interview with Trey Hunner discusses his use of automated tests to help teach programming. Automated testing is a huge part of developing great software. But many new developers don't get exposed to testing for quite a while. But this is changing. New ways to teach programming include automated tests from the beginning. Trey Hunner is one of the PSF directors and a Python and Django team trainer, and he has been using automated tests to help people learn Python.Special Guest: Trey Hunner.Sponsored By:Python Bytes: Get the latest Python news with the Python Bytes Podcast.Talk Python to Me: Get the back story and hear about the human side of the Python things you love with the Talk Python to Me PodcastLinks:Trey HunnerPython Morsels - write better Python codeTrey's Weekly Python ChatTrey's Training business: Truthful Technologyexercism.ioPyBites Code Challenges CheckiO ★ Support this podcast on Patreon ★

Adam is the host of The Gently Mad podcast, and teaches the steps in creating and growing a podcast in his course Irresistible Podcasting. He was one of the people who inspired Brian to get the Test & Code podcast started in the first place. Brian took his course in 2015. Adam is in the process of updating the course, and building a community around it. Warning: This may be an episode to listen to with headphones if you have kids around. There is swearing. I wanted to get Adam's help to convince many of you to either come on this show as a guest, or start your own podcast. We did some of that. But we also cover a lot of issues like self doubt and the importance of community.Special Guest: Adam Clark.Sponsored By:Python Testing with pytest, 2nd edition: The fastest way to learn pytest and practical testing practices.Patreon Supporters: Help support the show with as little as $1 per month and be the first to know when new episodes come out.Links:Irresistible Podcasting – A Step by Step Guide to Launching and Growing a Podcast that Can’t Be IgnoredThe Gently Mad – Life, business & entrepreneurship without the bullshit.avclark.comJustin Jacksons episodes on minimal podcasting | Build and LaunchDan Benjamin's Podcast Method podcastPython Bytes PodcastATR2100 MicShure SM57 MicShure SM7B micdbx 286s Microphone Preamp ProcessorFocusrite Scarlett 2i2 USB Audio Interface ★ Support this podcast on Patreon ★

Complete and exhaustive testing is not possible. Nor would it be fun, or maintainable, or a good use of your time. However, some functionality is important enough to make sure the test behavior coverage is thorough enough to have high confidence in it's quality. In this episode, we discuss 3 techniques that can be combined to quickly generate test cases. We then talk about how to implement them efficiently in pytest. The techniques covered are: equivalence partitioning boundary value analysis decision tables We discuss how to use these to generate test cases for a new list filter functionality in the cards application. The resulting tests: 1 UI test to make sure the options are able to be passed in correctly. 1 small parametrized test function with 16 single line parameter sets representing the different test cases.

RCRCRC was developed by Karen Nicole Johnson. In this episode we discuss the mnemonic/heuristic and use it to prioritize tests for the cards application. Recent: new features, new areas of code Core: essential functions must continue to work, your products USPs (Unique Selling Propositions) Risk: some areas of an application pose more risk, perhaps areas important to customers but not used regularly by the development team. Configuration sensitive: code that’s dependent on environment settings or operating system specifics Repaired: tests to reproduce bugs, tests for functionality that has been recently repaired. Chronic: functionality that frequently breaks Sponsored By:Patreon Supporters: Help support the show with as little as $1 per month and be the first to know when new episodes come out.Links:A heuristic for regression testing, by Karen Nicole Johnson@karennjohnsoncards on githubcards on Travis CIcards on AppVeyor ★ Support this podcast on Patreon ★
