Make fewer tests that are larger, because the tests are going to be extremely expensive and fragile. Make assertions that are very permissive, eg assert that you see a success message, but not what the message says. Because there's a million ways for these tests to fail. Someone changes some wording in a message and tests fail. Someone changes the DOM structure and the tests fail. Someone changes a classname and the tests fail. Some async operation takes longer than expected or resolves in some unexpected order, and the tests fail. But in all those situations, the thing you are testing is still correct, it's just that the way the test checks it is fragile, and the thing you are testing is volatile. So you want the tests to only assert the most important things, and the art of it is figuring out how permissive you want to be. Eg you want to be assertive enough that they don't accidentally pass when they actually should fail, but still permissive enough that they can tolerate irrelevant volatility.
