Possibly, but I suspect any tests for CHM will be more fragile and involved. My sense is it may be premature to do that right now.

To tickle the locations where ISEs are thrown the CHM compute functions probably need to perturb the bucket where the key computed on is, or is to be, located and tests might need to perform concurrent updates to induce resizes.
