As new features are being added to Frame, it may be helpful to add automated testing to the codebase for new features. GTest is already utilized in Mir, and while there isn't much worth unit testing in Frame, it may prove useful if it continues to expand.
Integration testing to ensure compatibility between Frame and various snaps would be even more useful, though I am unaware of a framework which is best in this case.
