I wish there was an independent unit test suite for operating systems and other proprietary software.

The suite would run the most-used apps and utilities against updates and report regressions.

So for example, the vast majority of apps on my Mac can't run, because they were written for early versions of OS X and OS 9, even all the way back to System 7 when apps were expected to still run on 4/5/6. The suite would reveal that Apple has a track record of de-prioritizing backwards compatibility or backporting bug fixes to previous OS versions.

Edit: integration test suite

The Android CTS is essentially this for device OEMs. https://source.android.com/docs/compatibility/cts – it's a set of tests that a customised Android implementation must pass.
