Pester Test

Question

Answer 1

Pester isn't that hard to learn. Search for "Pester tutorial" and you'll find more than a few items that are helpful. If you prefer a book, there's the "Pester Book" by Adam Bertram (I used it and found it to easy to understand and got into writing tests for modules within a day or two).

Posting the function's code isn't very helpful. You should really start by writing a few basic Pester tests and add more as you build the function. If you don't know what the function should be returning when given a set of parameters (in all possible combinations, including omitting parameters, and parameters that contain unexpected values) then you're "flying blind".

Once you built a set of tests and your function works as expected (as defined by the tests!), you can rerun the tests after making any changes to your code to verify that you haven't mistakenly altered the output!
