Since the tests in this package are concerned primilary with configuration evaluation and less concerned about configuration bundling or loading, most of our tests can just use subdirectories of the only package in this synthetic source bundle to avoid the inconvenience of maintaining an entire source bundle for each separate test.
To use this:
Make a subdirectory under test/ with a name that's related to your test case(s).
Use the loadMainBundleConfigForTest helper, passing the name of your test directory as the source directory.
(The helper function will automatically construct the synthetic remote source address needed to locate that subdirectory within the source bundle.)
