I'm watching your tutorial in Udemy and have to admit it's an amazing course, everything is clear and understandable. I came here to get some additional info, as you mentioned in your course and it's really helpful. Thank you.

This approach is okay, but not ideal. You should wait for the response before editing, so that you have a promise for that response. This way you not only wait for the actual response and can grab and assert the real value, but you also mitigate the possibility of waiting for an API call that has already occurred. In your example it’s unlikely to happen, but awaiting something after the action that triggers it introduces a small timing window where the call can be missed and the test may fail. This is the preferred approach in most cases, especially for applications with hydration issues.

What about methods like await networkidle? Or DOM loaded?

How to get playwright test runner ui which you are showing here ? Do we need to run any specific command for this ?

I'm curious about the occasional crash when running tests with more workers. I'm testing in a local environment, but I don't know why.
Also, is the screen shown in the video a trace viewer?
