Not a Go developer but bazel in Java does the same thing and it's really helpful when writing test cases. Say I am editing two test methods within a test suite of 30 test cases, it will run only those two tests. For the rest 28 it will show the cached output.

But thats the thing, this is not incremental compile/test. Its just checking the binary output (at least as far as I can tell).

That's different. Go will rerun all tests (for that binary)
