Test & Code : Python Testing for Software Engineering

Technology Podcasts

Test & Code is a weekly podcast hosted by Brian Okken. The show covers a wide array of topics including software engineering, development, testing, Python programming, and many related topics. When we get into the implementation specifics, that's usually Python, such as Python packaging, tox, pytest, and unittest. However, well over half of the topics are language agnostic, such as data science, DevOps, TDD, public speaking, mentoring, feature testing, NoSQL databases, end to end testing, automation, continuous integration, development methods, Selenium, the testing pyramid, and DevOps.

141: Visual Testing - Angie Jones

12/30/2020
Visual Testing has come a long way from the early days of x,y mouse clicks and pixel comparisons. Angie Jones joins the show to discuss how modern visual testing tools work and how to incorporate visual testing into a complete testing strategy. Some of the discussion: Classes of visual testing: problems with pixel to pixel testing DOM comparisons, css, html, etc. AI driven picture level testing, where failures look into the DOM to help describe the problem. Where visual testing fits into a...

140: Testing in Scientific Research and Academia - Martin Héroux

12/18/2020
Scientists learn programming as they need it. Some of them learn it in college, but even if they do, that's not their focus. It's not surprising that sharing the software used for scientific research and papers is spotty, at best. And what about testing? We'd hope that the software behind scientific research is tested. But why would we expect that? We're lucky if CS students get a class or two that even mentions automated tests. Why would we expect other scientists to just know how to test...

138: Mutation Testing in Python with mutmut - Anders Hovmöller

11/19/2020
Your test suite tells you about the quality of your code under test. Mutation testing is a way to tell you about the quality of your test suite. Anders Hovmöller wrote mutmut (https://mutmut.readthedocs.io/) for mutation testing in Python, and can be used with pytest, unittest, and others. In this episode, Anders explains mutation testing, how mutation testing with mutmut works, and good workflows. Special Guest: Anders Hovmöller.

135: Speeding up Django Test Suites - Adam Johnson

10/20/2020
All test suites start fast. But as you grow your set of tests, each test adds a little bit of time to the suite. What can you do about it to keep test suites fast? Some things, like parallelization, are applicable to many domains. What about, for instance, Django applications? Well, Adam Johnson has thought about it a lot, and is here to tell us how we can speed up our Django test suites. Topics include: parallelizing tests moving from disk to memory using fake data and factory functions...

130: virtualenv activation prompt consistency across shells - an open source dev and test adventure - Brian Skinn

9/13/2020
virtualenv supports six shells: bash, csh, fish, xonsh, cmd, posh. Each handles prompts slightly differently. Although the virtualenv custom prompt behavior should be the same across shells, Brian Skinn noticed inconsistencies. He set out to fix those inconsistencies. That was the start of an adventure in open source collaboration, shell prompt internals, difficult test problems, and continuous integration quirks. Brian Skinn initially noticed that on Windows cmd, a space was added between a...

I asked people on twitter to fill in "How do I test _____?" to find out what people want to know how to test. Lots of responses. David Lord agreed to answer them with me. In the process, we come up with lots of great general advice on how to test just about anything. Specific Questions people asked: What makes a good test? How do you test web app performance?

128: pytest-randomly - Adam Johnson

8/28/2020
Software tests should be order independent. That means you should be able to run them in any order or run them in isolation and get the same result. However, system state often gets in the way and order dependence can creep into a test suite. One way to fight against order dependence is to randomize test order, and with pytest, we recommend the plugin pytest-randomly to do that for you. The developer that started pytest-randomly and continues to support it is Adam Johnson, who joins us today...

124: pip dependency resolver changes

8/3/2020
pip is the package installer for Python. Often, when you run pip, especially the first time in a new virtual environment, you will see something like: WARNING: You are using pip version 20.1.1; however, version 20.2 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command. And you should. Because 20.2 has a new dependency resolver. Get in the habit, until October, of replacing pip install with pip install --use-feature=2020-resolver. This flag is new...
