With the new ability to pass --run=setup to select which tests to run, it is more convenient if tests use the term "setup" instead of synonyms like 'prepare' or 'rebuild'. There are undoubtedly many other tests in our testsuite that could be changed over too, these are just a couple that I ran into.
