Hi Carlos,
It’s not clear to me what you’re trying to accomplish with that example.
Meep#call has a rescue clause but the code being rescued involves no method
calls ("no error" is not a method call) and, barring something truly
bizarre like a busted ruby installation, cannot raise any sort of
exception. As there’s no possibility of an ArgumentError being raised,
there’s no point in rescuing it (or in trying to write a test to cover the
possibility of an exception being raised).
In addition, allow_any_instance_of(Meep).to
receive(:call).and_raise(ArgumentError) completely replaces your existing
implementation of Meep#call including the rescue ArgumentError.
I’m not sure what to suggest since your example doesn’t make sense to me.
