at Venmo

May 1 2014

Recently at Venmo, I spent some time improving our Python test suite. It was in pretty bad shape when I arrived: builds took 45 minutes and tests were flaky. Now, builds take 6 minutes and are much more dependable.

I was asked to write up some blog posts describing our changes, and I decided to start with mocking external interactions. The full post is at the Venmo engineering blog. Hopefully it’s helpful! Feel free to email me with questions.
