Part two in my “live”-style screencast series is now available! Watch me code up a small web app from scratch using test-driven development.
In this hour-long episode, I switch from integration testing to unit testing in order to drive out some more features for the Sinatra-based web service I’ve been building. You’ll see me:
- Use the “hub” gem to interact with GitHub.
- Talk about the decision point to drop from integration to unit testing.
- Use
IO.popen
to pipe text through an external process. - Isolate tests for filesystem interaction using simple dependency injection.
- Use
Enumerable#each_cons
and enumerators to identify a sub-sequence in an Array. - Use the
Pathname
standard library. - …and more!
Here’s a five-minute preview:
