Test & Code - Python Testing & Development

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.

This episode starts down the path of test strategy with the first tests to write in either a legacy system or a project just getting off it's feet. We cover: My approach to testing existing systems. Put names to strategies so we can refer to them later. Explain the strategies in general terms and explain why they are useful. Discuss how these strategies are used in an example project. (The code is available on github). Strategies covered today: Dog Fooding Exploratory Testing Tracer Bullet Tests Act Like A Customer (ALAC) Tests Manual Procedures Initial automated tests at 2 levels, API and UI.

Stephanie is a co-founder and graphics engineer at Binomial. She works on Basis, an image compressor, and has customers in games, video, mapping, and any application that has lots of image data. Stephanie has also been encouraging experienced engineers to open up their twitter DMs to questions from anyone, to help mentor people not only in technical questions, but in career questions as well. She also sets aside some time to mentor people through skype when written form just doesn't cut it. That's the primary reason I have Stephanie on today, to talk about mentoring and open office hours. But we also talk about Binomial image compression texture mapping the use of both manual and automated testing for complex systems sane work hours work life balance and how long hours have led her to the opinions she holds today Special Guest: Stephanie Hurlburt.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.

There are lots of ways to up your skills. Of course, I'm a big fan of learning through reading books, such as upping your testing skills by reading Python Testing with pytest. And then there are online learning systems and MOOCs. At the other end of the spectrum is a full blown university degree. One option kind of in the middle is continuing education programs available through some universities, such as University of Washington. To discuss this option with me in more depth, we've got Andrew Hoover, Senior Director, Program Strategy, University of Washington Continuum CollegeSpecial Guest: Andrew Hoover.Sponsored By: Python Testing with pytest, 2nd edition: The fastest way to learn pytest and practical testing practices.

An in depth discussion of Test Driven Development (TDD) should include a discussion of Test First. So that's where we start. Why write tests first? How do you know what tests to write?

A discussion with Katharine Jarmul, aka kjam, about some of the challenges of data science with respect to testing. Some of the topics we discuss: experimentation vs testing testing pipelines and pipeline changes automating data validation property based testing schema validation and detecting schema changes using unit test techniques to test data pipeline stages testing nodes and transitions in DAGs testing expected and unexpected data missing data and non-signals corrupting a dataset with noise fuzz testing for both data pipelines and web APIs datafuzz hypothesis testing internal interfaces documenting and sharing domain expertise to build good reasonableness intermediary data and stages neural networks speaking at conferences Special Guest: Katharine Jarmul.Sponsored By: Python Testing with pytest, 2nd edition: The fastest way to learn pytest and practical testing practices.

A wonderful discussion with David Hussman. David and Brian look back at what all we've learned in XP, TDD, and other Agile methodologies, where things have gone awry, how to bring the value back, and where testing fits into all of this. How to build the wrong thing faster Agile vs Agility Product vs Process Where testing fits into software development practices. "Integration tests, there's a name that needs to be refactored desperately." Integration tests are "story tests". They tell the story of the product. XP and TDD and the relationship with tests To test for design, use microtests, xUnit style. User Advocy tests are often lacking, but are needed to learn about the product. "I just keep writing tests until I'm not scared anymore." - Kent Beck Dude's Law: Value = Why/How People often focus so much on the how that they forget about why they are doing something. Subcutaneous Tests "The hardest part of programming is thinking." Refactoring vs Repaving Agility means being able to quickly change direction D

What started as a twitter disagreement carries over into this civil discussion of software testing.

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

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

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.
