Helper that tries to find out what test suite is running (for SimpleCov.command_name)
Storage for the original command line call that invoked the test suite. This has got to be stored as early as possible because i.e. rake and test/unit 2 have a habit of tampering with ARGV, which makes i.e. the automatic distinction between rails unit/functional/integration tests impossible without this cached item.
