I don't think this test is working. If you wrote your code such as
`WebDisplayBrowser` returns "foobar" and "foobar" is interpreted as
`WebDisplayBrowser`, the test would pass but I don't think it would mean the
implementation is correct.

Maybe you should test one method at a time?

I am banking on ManifestParserTest#OrientationParserRules() testing
content::WebScreenOrientationLockTypeToString()
- Should I add a comment to make this assumption more explicit
- Should I move ManifestParserTest#OrientationParserRules() to
manifest_util_unittest.cc ?
