Interview with Sam Van Oort about pyresttest, "A REST testing and API microbenchmarking tool" pyresttest A question in the Test & Code Slack channel was raised about testing REST APIs. There were answers such as pytest + requests, of course, but there was also a mention of pyresttest, https://github.com/svanoort/pyresttest, which I hadn't heard of. I checked out the github repo, and was struck by how user friendly the user facing test definitions were. So I contacted the developer, Sam Van Oort, and asked him to come on the show and tell me about this tool and why he developed it. Here's the "What is it?" section from the pyresttest README: A REST testing and API microbenchmarking tool Tests are defined in basic YAML or JSON config files, no code needed Minimal dependencies (pycurl, pyyaml, optionally future), making it easy to deploy on-server for smoketests/healthchecks Supports generate/extract/validate mechanisms to create full test scenarios Returns exit codes on failure, to slot into automated configuration management/orchestration tools (also supplies parseable logs) Logic is written and extensible in Python Support Special thanks to my wonderful Patreon supporters and those who have supported the show by purchasing Python Testing with unittest, nose, pytestSponsored 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. ★ Support this podcast on Patreon ★

pytest is an extremely popular test framework used by many projects and companies. In this episode, I interview Raphael Pierzina (@hackebrot), a core contributor to both pytest and cookiecutter. We discuss how Raphael got involved with both projects, his involvement in cookiecutter, pytest, "adopt pytest month", the pytest code sprint, and of course some of the cool new features in pytest 3.

Kent Beck's twitter profile says "Programmer, author, father, husband, goat farmer". But I know him best from his work on extreme programming, test first programming, and test driven development. He's the one. The reason you know about TDD is because of Kent Beck. I first ran across writings from Kent Beck as started exploring Extreme Programming in the early 2000's. Although I don't agree with all of the views he's expressed in his long and verbose career, I respect him as one of the best sources of information about software development, engineering practices, and software testing. Along with Test First Programming and Test Driven Development, Kent started an automated test framework that turned into jUnit. jUnit and it's model of setup and teardown wrapping test functions, as well base test class driven test frameworks became what we know of as xUnit style frameworks now, which includes Python's unittest. He discussed this history and a lot more on episode 122 of Software Engineering Radio. The episode is titled "The History of JUnit and the Future of Testing with Kent Beck", and is from Sept 26, 2010. http://www.se-radio.net/2010/09/episode-167-the-history-of-junit-and-the-future-of-testing-with-kent-beck/ I urge you to download it and listen to the whole thing. It's a great interview, still relevant, and applicable to testing in any language, including Python. What I've done in this podcast is take a handful of clips from the interview (with permission from IEEE and SERadio), and discuss the clips and my opinions a bit. The lessons are: You're tests should tell a story. Be careful of DRY, inheritance, and other software development practices that might get in the way of keeping your tests easy to understand. All test should help differentiate good programs from bad programs and not be redundant. Test at multiple levels and multiple scales where it makes sense. Differentiating between TDD, BDD, ATDD, etc. isn't as important as testing your software to learn about it. Who cares what you call it.

Interview with Robert Collins, current core maintainer of Python's unittest module. Some of the topics covered How did Robert become the maintainer of unittest? unittest2 as a rolling backport of unittest test and class parametrization with subtest and testscenarios Which extension to unittest most closely resembles Pytest fixtures? Comparing Pytest and unittest Will unittest ever get assert rewriting? Future changes to unittest I've been re-studying unittest recently and I mostly wanted to ask Robert a bunch of clarifying questions. This is an intermediate to advanced discussion of unittest. Many great features of unittest go by quickly in this talk. Please let me know if there's something you'd like me to cover in more depth as a blog post or a future episode.

In this episode, I interview with Joe Stump, cofounder of Sprintly (https://sprint.ly), to give the startup perspective to development and testing. Joe has spent his career in startups. He's also been involved with hiring and talent acquisition for several startups. We talk about testing, continuous integration, code reviews, deployment, tolerance to defects, and how some of those differ between large companies and small companies and startups. Then we get into hiring. Specifically, finding and evaluating good engineers, and then getting them to be interested in working for you.
