A new requirement was introduced in DRIVERS-1967 that drivers run all of their unified tests against serverless. This currently requires us to maintain a manual list of unified tests we want to run in the run-serverless-tests.sh script. 

If we move all of our unified tests into a single module this could simplify keeping that up to date as we could just run all tests for that module from this script. It would also make it simple to (for example) confirm that a unified test runner change doesn't break any tests without needing to run the entire test suite.
