Maybe a better example would be in place. Consider the following
from the Autotest plugin:
Autotest.add_discovery do
"rspec" if File.exist?('spec')
end
How would you go about testing this?
It's easy enough to test that Autotest receives the method
add_discovery. But how would you deal with the block?
