Issue Resolved / Feature Added

Enact libraries like Sandstone have a few code to work on specific browser versions or specific platform environments but we don't test those logics in unit tests due to lack of mocking. So we should investigate how to mock core/platform and webos/platform in unit tests

Resolution

I added an example unit test here (https://github.com/enactjs/sandstone/pull/1605) to show how to mock core/platform or webos/platform. We can mock core/platform or webos/platform by parsing "mock userAgent". By the way, if platform information is detected once by parsing user agent, "detectedPlatform" is used after that. We can't test multiple platform in one unit test file. So I made "resetPlatformDescription" function to reset detected platform information.
