ConsoleSpy



I was working recently on a project where a function would print to the console when it was executed. I was practicing writing more tests, so I wanted to verify that this function was executing properly and figured there’d be a way to do that with tests.

The problem was I didn’t know how. It turns out this was a great opportunity to learn more about mocks and spys - concepts I’d heard plenty about when it came to testing but so far hadn’t found a need to explore.

This works! Even better - it’s simple!

  • Spy is a flexible, lightweight, multiplatform logging utility written in pure Swift. It allows to log on different levels and channels which you can define on your own depending on your needs.
  • Keep an eye on the system.log and filter the messages by using custom alert strings in order to de. May 25th 2016, 14:10 GMT.

You can confirm it by changing the function to warn or error instead of logging. There are a few issues with this approach though: namely, it’s polluting the global namespace and any other test that might rely on that functionality in this test could be unreliable.

An alternative (better) approach is to use jest’s spyOn functionality.

Spys aren’t full proof though. They have the same potential danger. For example, if we didn’t clear the mock before each test, we could end up in the same situation where our tests are unreliable.

Take for instance the following example:

The “eerily similar test” would fail because the call count wasn’t reset.

This project was one of the first where I had the opportunity to write tests from the get go and I have to say, it’s been a lot of fun! I haven’t taken a TDD approach, but more of a behavioral one - testing the behavior I expect my code to take. Along the way I’ve had to move code around, refactor a few times, and each time - it’s been a really smooth process. It’s fascinating! Excited to continue exploring how to take advantage of tests!
