Struggling with learning testing (self.learn_programming)

I am really struggling to include proper testing practices into my code and would appreciate any advice on how to get going. I work in web dev so my I am interested in how to properly implement a suite of tests for websites and incorporate into it a CI/CD pipeline.

I find a lot of tutorials teach the most basic types of unit tests, 90% of the time most instructors teach how to write a test to sum two numbers, but when it comes to writing real unit test I find it hard to know what I should be testing. I learnt some cypress and have gotten better at including end-to-end testing because that makes more sense to me, but I still feel I am way short of where I should be.

How can I move forward? Did anyone else find themselves in my situation and find good resources to help them learn? Thx

A bit late to this thread but what helped me a lot was when I started doing TDD. By testing my code against tests before its fully done or even implemented in the main app codebase (so to speak), I could break down individual tasks in it more easily and see how its interior parts work. It seemed easier to separate it into SRP areas since they'd have to stick to the unit test for that responsibility. Do keep in mind you can take it too far and overengineer it in this way but it was a good kick in the butt to get me to think in a different way.

Where did you learn TDD. I mean I know the concept, but are there good courses for how to implement it into modern web stacks like React, Svelte etc

Saying I learned it is a stretch, we still dont use it at my workplace and I just read some random guides and tried it on my personal projects. I also wouldn't know about using it in frontend, I mostly just use it to make it easier to test my backend (c#) methods during development without having to struggle with setting up reproduction steps and go through the entire frontend every time.
