Test & Code :  Python Testing for Software Engineering

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.



12: Coverage.py with Ned Batchelder

In this episode I interview Ned Batchelder.

I know that coverage.py is very important to a lot of people to understand how much of their code is being covered by their test suites.
Since I'm far from an expert on coverage, I asked Ned to discuss it on the show.

I'm also quite a fan of Ned's 2014 PyCon talk "Getting Started Testing", so I definitely asked him about that.

We also discuss edX, Python user groups, PyCon talks, and more.

Some of what's covered (pun intended) in this episode:

  • coverage.py
    • types of coverage
      • Line coverage
      • branch coverage
      • Behavior coverage
      • Data coverage
    • How Ned became the owner of coverage.py
    • Running tests from coverage.py vs running coverage from test runner.
  • edX
    • what is it
    • what Ned's role is
  • Ned's blog
  • Ned's PyCon 2014 talk "Getting Started Testing"
    • Teaching testing and the difficulty of the classes being part of unittest
    • fixtures package
    • some of the difficulties of teaching unittest because of it's class based system.
    • the history of classes in unittest coming from java's jUnit implementation
  • Boston's Python Group
  • PyCon in Portland
  • Ned to do a talk here "Machete mode debugging".
  • Practicing PyCon talks at local group meetings.
  • At the very least, practice it in front of a live audience.
