Furthermore the test does not actually verify that the flair was set in the case that the flair was already set on that particular Submissions. For instance if I only run this test over and over again, subsequent tests do not tell me anything new.

I might suggest combining the two tests in a manner such that the custom text test always runs first, since that one is repeatable:

```
get_submission
set_and_test_custom_text
set_and_test_default_text
```
