12: Coverage.py with Ned Batchelder
40:38 Share

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.
