ruby - How to test a method is called with Minitest? -

class post   def save     mailer.notify!('bla')     true   end end 

how test when post.save called, mailer.notify method fired? , right arguments.

with rspec do:

expect(mailer).to receive(:notify!).with('bla') post.save 

thank in advance!

you can this:

describe 'post#save'   "calls mailer::notify!"     mock = minitest::mock.new     mock.expect(:call, nil, ['bla'])      mailer.stub(:notify!, mock)       post.save     end      mock.verify   end end 

and yes, easier , more intuitive in rspec...
