Handling integration and UI tests that are missing their prerequisite

I just have a simple question. For integration tests to the backend and automated UI tests that are missing their prerequisites (eg. the test accounts sign in to the app), do you set the tests as failed or just completely ignore those tests? I am in the process of refactoring my tests and this comes out because when I try checking the backend, my usual test accounts are gone and the tests are all failing. So I can't be sure if this won't happen again in the future.

Thanks.
