⚠️ If you run tests from SurveyFramework framework on an iOS target you'll see two tests test_load_returnsSavedToken and test_load_returnsLastSavedToken fails due to testing Keychain requires a host application. You can make it pass by either:

1. Create a host iOS application and run the tests on it.
2. Run the tests on macOS target.

1. Contains business logic.
2. platform-agnostic. Can run on any platforms (iOS, macOS, iPadOS, tvOS, WatchOS).
3. Total 32 test cases.
4. Coverage: 93,7%.
5. Total run time: 0.456 seconds.

1. Contains UI+Representation Layer.
2. Contains compositions.
3. Platform-specific (iOS).
4. Total 69 test cases.
5. Coverage: 81,3%.
6. Total run time: 0.8 seconds.
