It wouldn't be bad to test on negative numbers as well. That would mostly be a test for shader execution, rather than shader compilation, but it's still useful. Also, eventually we'll add constant folding to square root too, and it would be useful to know what is supposed to happen. BTW, that applies to `sqrt()` as well.
As I understand, the only reason we test by execution is because matching compiler output exactly is not really required, or needs a lot of work and time, that's better spent elsewhere. For constants that applies to all other tests as well.
