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. ★ Support this podcast on Patreon ★

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.Links:BinomialList of Engineers Willing to Mentor You — Stephanie HurlburtStephanie Hurlburt (@sehurlburt) | TwitterSlack - Python Testing / Test & Code — A super nice group of folks who are great at answering test related questions. ★ Support this podcast on Patreon ★

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.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:UW Professional & Continuing EducationUW Career Accelerator CertificatesCertificate in Data AnalyticsCertificate in Data ScienceCertificate in Machine LearningCertificate in Project ManagementCertificate in Python Programming ★ Support this podcast on Patreon ★

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? What are the steps for test first? Isn't this just TDD?

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.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:@kjam on Twitter — Data Magic and Computer SorceryKjamistan: Data Sciencedatafuzz’s Python library — The goal of datafuzz is to give you the ability to test your data science code and models with BAD data.Hypothesis Python library — Hypothesis is a Python library for finding edge cases in your code you wouldn’t have thought to look for. ★ Support this podcast on Patreon ★

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 During experimentation and learning, what matters isn't how much you got done, but how much you learn. "The best way to get automation is to make developers do manual tests."

What started as a twitter disagreement carries over into this civil discussion of software testing. Brian and Paul discuss testing practices such as the testing pyramid, TDD, unit testing, system testing, and balancing test effort. the Testing Pyramid the Testing Column TDD unit testing balancing unit with system tests, functional tests API testing subcutaneous testing customer facing tests Special Guest: Paul Merrill.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.Nerdlettering: Love Python?
