I think the test coverage is needed to help ensure the functionality would not be broken by future changes.

Detected through mutation testing (PR #61) of watchkit2 updates (PR #56).

I believe I've covered this in #66, but I haven't finished running Stryker on it yet.

I believe I've covered this in #66, but I haven't finished running Stryker on it yet.

Thanks again @l3ender for your help.

You can see in PR #66 that I did already check by hand that it does cover the possible changes discussed here.

I wouldn't worry too much about finishing the run on Stryker at this point. As I said in PR #63, Stryker takes a really, really long time if we don't use something like 16 CPUs worth of computing power.
