Pester and Testable Powershell Scripts

Shane O’Neill has a public service announcement:

Now scripts are notoriously hard to test, I’ve written about how I’ve done that before but, honestly, if you really want to know then you need to check out Jakub Jares ( blog | twitter ).

Knowing how difficult testing scripts are, the first thing I decided to do was take the functions in the script and split them out. This way they can be abstracted away and tested safely.

I also didn’t want to take on too much at one time so I choose a random function, GetPreviousTag, and only actioned that one first.

Shane also found a bug in the first script, underscoring the importance of good tests.
