This won't work, it will always resolve to true.
We need here to wait for it to be the length of the number of files we have pushed in the test setup, thus that defines the expected state of the app loaded. However in one test the length of this would be `0` ! I know passing in an expected value is not very normal for an app object but this is the most reliable way we can get it to wait. got any ideas for working around it?
