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

    • Behavior coverage
    
    
    • Data coverage
    
    
  
  
  • How Ned became the owner of coverage.py
  
  
  • Running tests from coverage.py vs running coverage from test runner.
