Having automated tests recently saved me from adding a regression to a project.

Continuing from [my last few emails ]({{site.url}}/daily/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.
