Test Driven Development, TDD, can be intimidating to try. Why is that? And how can we make it less scary? That's what this episode is about. Chris May is a Python developer and the co-founder of PyRVA, the Richmond Virginia Python group. In this episode, Chris shares his experience with adding testing and TDD to his work flow. I really enjoyed talking with Chris, and I think his story will help lots of people overcome testing anxiety.Special Guest: Chris May.Sponsored By: PyCharm Professional: Try PyCharm Pro for 4 months.

Software testing, if done right, is done all the time, throughout the whole life of a software project. This is different than the verification and validation of a classical model of QA teams. It's more of a collaborative model that actually tries to help get great software out the door faster and iterate quicker. One of the people at the forefront of this push is Alan Page. Alan and his podcast cohost Brent Jensen tried to boil down what modern testing looks like in the Modern Testing Principles. I've got Alan here today, to talk about the principles, and also to talk about this transition from classical QA to testing specialists being embedded in software teams and then to software teams doing their own testing. But that only barely scratches the surface of what we cover. I think you'll learn a lot from this discussion. The seven principles of Modern Testing: Our priority is improving the business. We accelerate the team, and use models like Lean Thinking and the Theory of Constraints to help identi

In this episode, I talk with Derrick Mar, CTO and co-founder of Pathrise. This is the episode you need to listen to to get ready for software interviews. We discuss four aspects of technical interviews that interviewers are looking for: communication problem solving coding verification How to practice for the interview. Techniques for synchronizing with interviewer and asking for hints. Even how to ask the recruiter or hiring manager how to prepare for the interview. If you or anyone you know has a software interview coming up, this episode will help you both feel more comfortable about the interview before you show up, and give you concrete tips on how to do better during the interview.Special Guest: Derrick Mar.Sponsored By: Python Testing with pytest, 2nd edition: The fastest way to learn pytest and practical testing practices.

This is a "Yay! It's PyCon 2019" episode. PyCon is very important to me. But it's kinda hard to put a finger on why. So I figured I'd ask more people to help explain why it's important. I ask a few simple questions to people about Python and PyCon and get some great insights into both the language popularity and the special place this conference holds to many people.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.

Some typical technical interview practices can be harmful and get in the way of hiring great people. April Wensel offers advice to help fix the technical interview process. She recommends: hire for mindset and attitude look for empathy and mentorship skills allow candidates to show their strengths instead of hunting for weaknesses have the candidate leave feeling good about themselves and your company, regardless of the hiring decision Some topics discussed: interview questions to bring out stories of skills and successes stereotype threat diversity interview hazing white boards coding challenges unconscious bias emotional intelligence myth of talent shortage pair programming and collaboration during interviews mirrortocracy cultural add vs cultural fit empathy mentoring This episode is important for anyone going into a technical interview, as a candidate, as a hiring manager, or as a member of an interview team.Special Guest: April Wensel.Sponsored By: Patreon Supporters: Help support the show with

Andy Hunt and Dave Thomas wrote the seminal software development book, The Pragmatic Programmer. Together they founded The Pragmatic Programmers and are well known as founders of the agile movement and authors of the Agile Manifesto. They founded the Pragmatic Bookshelf publishing business in 2003. The Pragmatic Bookshelf published it's most important book, in my opinion, in 2017 with the first pytest book available from any publisher.

With conventional TDD, you write a failing test, get it to pass, then refactor. Then run the tests again to make sure your refactoring didn't break anything. But what if it did break something? Kent Beck has been recommending to commit your code to revision control after every green test run. Oddmund Strømme suggested a symmetrical idea to go ahead and revert the code when a test fails. Kent writes that he hated the idea, but had to try it. Then wrote about it last September. And now we have TCR, "(test && commit) || revert". What's it feel like to actually do this? Well, Thomas Deniffel has been using it since about a month after that article came out. In this episode, we'll hear from Thomas about his experience with it. It's a fascinating idea.

Is it ok to have more than one assert statement in a test? I've seen articles that say no, you should never have more than one assert. I've also seen some test code made almost unreadable due to trying to avoid more than one assert per test. Where did this recommendation even come from? What are the reasons? What are the downsides to both perspectives? That's what we're going to talk about today.Sponsored By: PyCharm Professional: Try PyCharm Pro for an extended 4 month trial before deciding which version you need.

I want you to get the most out of being a software developer, or test engineer, or whatever you do that makes this podcast relevant to your life. By "get the most" I mean: the most fun the most value more career options probably more responsibility maybe even more money, that'd be cool I want you to start (or continue) studying and practicing your skills. But not just random practice, I've got a strategy to help you focus what to study. Why am I talking about this now? Here's some background on how I re-learned how to have fun with code refactoring through code challenges.

This interview definitely falls into the category of talking with interesting people doing interesting things with Python.

Let's say you've got a web application you need to test. It has a REST API that you want to use for testing. Can you use Python for this testing even if the application is written in some other language? Of course. Can you use pytest? duh. yes. what else? What if you want to spin up docker instances, get your app running in that, and run your tests against that environment? How would you use pytest to do that? Well, there, I'm not exactly sure.
