In Playwright (Python) when there are multiple buttons on a page, all with the same name, how do i select correct button?

Trying to select the option

Each test must be independent from the rest. As you said, your test_delete_user can not depend on your test_create_user.

What I do? For my test test_create_user:

  • Load website
  • Create user
  • Use expect statement to verify it worked
  • In case you don't want to leave trash in the DB, then you can have another DB query for deleting that new user, but if this query does not work, the test should not fail.

For my test test_edit_user:

  • Load website
  • I always edit same user
  • Use expect statement to verify it worked

For my test test_delete_user:

  • Precondition: I have a query to DB to insert an user, then my test starts.
  • Load website
  • Delete user
  • Use expect statement to verify it worked

I do it like this because each test is independent, lets imagine the function for deleting an user is working but your function for create user is not working, if your test were like this:

  • Load website
  • Create user
  • Delete user
  • Use expect statement to verify it worked

You will get a falsy error saying that your test_delete_user is not working, but actually it is.
