Doing a lot of testing is totally fine. I recently got into a "Lead Developer" position and if I get a PR that is not well tested, the time I waste testing something that doesn't work is worse than waiting for the developer to properly test the thing before passing it on to me. I'd rather wait a bit more but be 99% sure that I could merge without additional testing. So, from my perspective, taking a bit more time with testing is no issue as long as you actually test all edge cases and your higher-up knows they can rely on your ability without having to double check everything.

As for taking 3-4 tries, I think that if you stick with it, you'll get better as time goes. Learning about design patterns, even if the tutorials seem worthless at first, might come in handy. Better to be aware of the patterns before you need them than after.
