Alright, so I was messing around with this thing called “Dream Router” and trying to get a handle on its code coverage. You know, making sure all the lines of code are actually being tested. Here’s how it went down:
First Steps – Getting Set Up
First things first, I needed to actually install Dream Router. I already had a project going, so I just popped open my terminal and ran the command to add it as a dependency. Pretty standard stuff.
Running the Tests (and seeing the mess)
Next up, I wanted to see where I stood. I ran the tests that were already in place. The output was a giant wall of text – a bunch of passing tests, which was cool, but also a big, glaring number showing the overall coverage percentage. It was… not great. Let’s just say there was plenty of room for improvement.
Finding the Untested Stuff
So, I dug around and found files that were pretty much ignored by the tests. These were usually helper functions, utility stuff, or maybe some edge-case handling that the existing tests just didn’t touch.
Writing More Tests
- Targeted Tests: I started writing new tests, specifically targeting those uncovered areas. I’d look at a function, figure out what it was supposed to do, and then write a test to make sure it actually did that.
- Edge Cases are Key: A lot of the uncovered code was handling weird situations, like what happens if you give the function bad input, or if something unexpected happens along the way. So, I made sure to test those edge cases too. Empty strings, null values, that sort of thing.
It became the tough part.
Rinse and Repeat
After writing a bunch of new tests, I’d run the tests again. The coverage number would (hopefully) go up. Then, I’d look for any remaining uncovered areas and repeat the process. It was a bit tedious, but also kinda satisfying to see that coverage number creep higher and higher.
The Final Result
I didn’t get to 100% coverage. It can be hard to hit. But I did get it way higher than it was before. And more importantly, I felt a lot more confident that the code was actually working the way it was supposed to, even in those weird edge cases. Plus, having more tests makes it easier to change things later without accidentally breaking something.
So, that’s my story about wrestling with Dream Router coverage. Not the most glamorous task, but definitely a worthwhile one.
