        mach test accepts arguments specifying which tests to run. Each argument

        * A test suite name
        * An alias to a test suite name (codes used on TreeHerder)

        If no input is provided, tests will be run based on files changed in
        the local tree. Relevant tests, tags, or flavors are determined by
        IMPACTED_TESTS annotations in moz.build files relevant to the
        changed files.

        When paths or directories are given, they are first resolved to test
        files known to the build system.

        If resolved tests belong to more than one test type/flavor/harness,
        the harness for each relevant type/flavor will be invoked. e.g. if
        you specify a directory with xpcshell and browser chrome mochitests,
        both harnesses will be invoked.
