🧪 Testing: Fill in test coverage for createDevelopment

Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

#695 added a bunch of code changes. I didn't fully unit test them - not because I was too impatient to write tests (me?! never!!), but because I wanted to leave some good first issues as followups. Definitely that.

createDevelopment is missing unit test coverage for several dozen lines. The createDevelopment function doesn't have a dedicated createDevelopment.test.ts file. Let's make one!

Additional Info

We don't need a single unit test per && case. That would be quite annoying to write & maintain! Instead, I think maybe a couple tests would be fine:

• One test for all exclude* options being enabled
• One test for no exclude* options being enabled

If the tests are giving you grief, feel free to send an incomplete Draft PR with comments asking for help. ❤️

Note that the code might have been refactored since this issue was filed. Names might be slightly off. The general spirit of this issue should still be valid though.

Oop, looks like this has 100% unit test coverage. Thanks for pointing out @DemianParkhomenko!

For any issue around filling in test coverage: I might coincidentally accidentally fix it without noticing 😅. But in general, any code logic missing unit test coverage is fair game!
