146: Automation Tools for Web App and API Development and Maintenance - Michael Kennedy

Building any software, including web apps and APIs requires testing. There's automated testing, and there's manual testing. In between that is exploratory testing aided by automation tools. Michael Kennedy joins the show this week to share some of the tools he uses during development and maintenance. We talk about tools used for semi-automated exploratory testing. We also talk about some of the other tools and techniques he uses to keep Talk Python Training, Talk Python, and Python Bytes all up and running smoothly. We talk about: Postman ngrok sitemap link testing scripts for manual processes using failover servers during maintenance, redeployments, etc gitHub webhooks and scripts to between fail over servers and production during deployments automatically floating IP addresses services to monitor your site: StatusCake, BetterUptime the affect of monitoring on analytics crash reporting: Rollbar, Sentry response times load testing: Locus Full TranscriptSpecial Guest: Michael Kennedy.Sponsored By:Linode: If it runs on Linux, it runs on Linode.

144: TDD in Science - Martin Héroux

Test Driven Development, TDD, is not easy to incorporate in your daily development. Martin and Brian discuss TDD and testing and Martin's experience with testing, TDD, and using it for code involved with scientific research. We discuss lots of topics around this, including: What is TDD? Should research software be tested in order to be trusted? Time pressure and the struggle to get code done quickly. How do you make time for tests also? Is testing worth it for code that will not be reused? Sometimes it's hard to know how to test something. Maybe people should learn to test alongside learning how to code. A desire for a resource of testing concepts for non-CS people. Are the testing needs and testing information needs different in different disciplines? Biology, Physics, Astrophysics, etc. Do they have different testing needs? Do we need a "how to test" resource for each? Full TranscriptSpecial Guest: Martin Héroux.Sponsored By:Linode: If it runs on Linux, it runs on Linode.

143: pytest markers - Anthony Sottile

Completely nerding out about pytest markers with Anthony Sottile. Some of what we talk about: Running a subset of tests with markers. Using marker expressions with and, or, not, and parentheses. Keyword expressions also can use and, or, not, and parentheses. Markers and pytest functionality that use mark, such as parametrize, skipif, etc. Accessing markers with itermarkers and get_closest_marker through item. Passing values, metadata through markers to fixtures or hook functions.

141: Visual Testing - Angie Jones

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 test strategy. Combining "does this look right" visual testing with other test workflows. "A picture is worth a thousand assertions" - functional assertions built into visual testing. Baselining pictures in the test workflow.

140: Testing in Scientific Research and Academia - Martin Héroux

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 their code?

139: Test Automation: Shifting Testing Throughout the Software Lifecycle - Nalin Parbhu

Talking with Nalin Parbhu about the software evolution towards more test automation and the creation of Infuse and useMango. We talk a software development and "shift left" where automated tests and quality checks have moved earlier into the software lifecycle. Software approaches and where quality fits in Shift left Test automation Roles of software developers, SDETs (software development engineer in test), testers, QA, etc. Developers doing testing and devops Automated testing vs manual testing Regression testing, UI testing, black bock testing Unit testing, white box, API, end to end testing User acceptance testing (UAT) Mullet Methodology (Agile at the front, Waterfall at the back) Waterwheel Methodology (Requirements -> iterative development -> QA) What's an agile team?

138: Mutation Testing in Python with mutmut - Anders Hovmöller

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 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.Sponsored By:Electronic Specifier Insights: Podcast with reviews from electronics shows and latest tech electronics companies are releasingPyCharm Professional: Try PyCharm Pro for 4 months and learn how PyCharm will save you time.
