Complete and exhaustive testing is not possible. Nor would it be fun, or maintainable, or a good use of your time.

However, some functionality is important enough to make sure the test behavior coverage is thorough enough to have high confidence in it's quality.

In this episode, we discuss 3 techniques that can be combined to quickly generate test cases. We then talk about how to implement them efficiently in pytest.

The techniques covered are:

We discuss how to use these to generate test cases for a new list filter functionality in the cards application.

The resulting tests:

Stephanie is a co-founder and graphics engineer at Binomial.

She works on Basis, an image compressor, and has customers in games, video, mapping, and any application that has lots of image data.

Stephanie has also been encouraging experienced engineers to open up their twitter DMs to questions from anyone, to help mentor people not only in technical questions, but in career questions as well.

She also sets aside some time to mentor people through skype when written form just doesn't cut it.

That's the primary reason I have Stephanie on today, to talk about mentoring and open office hours.

But we also talk about

There are lots of ways to up your skills.

At the other end of the spectrum is a full blown university degree.

One option kind of in the middle is continuing education programs available through some universities, such as University of Washington.

To discuss this option with me in more depth, we've got Andrew Hoover,

An in depth discussion of Test Driven Development (TDD) should include a discussion of Test First. So that's where we start.
