It would be possible to move this code to a module, although the specific
needs of every test would be different, for example the clean and add
functions must be different for everyone. I would leave it here and check
the needs of other test to check if this can be reused. I would do that
work, because I'm already familiar with this.

Because some other system could have pushed before and our branch is
not up date.

It will throw an exception, that I think is good here, because your host
won't be publishing the results, and for the consumer is like this test
never happened. Usually you will act more on an exception than in a warning.
