How can I effectively find recurring bugs during manual testing?

One big issue I've seen is relying on type checkers and linters but still missing out on basic bugs. Sometimes, it’s those little mistakes like using `=` instead of `==` that can drive you nuts. Plus, unexpected CSS behavior across different browsers and devices can be infuriating! I focus on Test-Driven Development (TDD) and keep my tests right under the functions as a form of documentation, which really helps in catching issues early on. If you're looking for a solid strategy, that's what I recommend!.

I totally get your struggle! One tip is to document edge cases that are tough to manually test. This way, you have a checklist when you’re reviewing that part of the code. Also, if you notice a type-related bug, you might want to consider using TypeScript to catch those issues earlier.

Automated tests can really save your day! When I fix a bug, I always write tests to prevent it from cropping up again. For example, I had a recurring issue with mismatched character encodings in our project. After I added tests for Unicode checking, it immediately flagged the bug whenever something went wrong. So, definitely consider setting up a CI/CD that works for your stack!

The most common recurring problems I've faced are usually due to assumptions about user behavior. Just when you think users won't do something, they do! For UI bugs, I suggest investing in unit and end-to-end testing. And never underestimate the value of keeping your dependencies updated—it can really help prevent those sneaky bugs from hiding in older code.
