Continuing from [my last few emails]({{site.url}}/archive/2024/01/30/tdd-doesnt-mean-you-know-everything-upfront), as well as adding the new use case more easily and quicker, having automated tests also saved me from adding a regression into the code I was changing.
|
|
|
|
I'd written a condition in the query to ensure only results that started with the search term.
|
|
|
|
Initially, I removed it, but then the tests failed.
|
|
|
|
This reminded me why I'd written the condition that way, and I was able to re-add my fix differently.
|
|
|
|
Without the tests, I'd likely have removed it and introduced a regression.
|
|
|
|
Whilst fixing a bug, I'd have introduced a different bug.
|
|
|
|
My tests saved me from doing that and I was able to rectify it quickly before pushing to CI or the staging environment.
