To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!
More about adding a collaboratorMessage expectations
Basics
# create a double
obj = double()
# expect a message
obj.should_receive(:message)
# specify a return value
obj.should_receive(:message) { 'this is the value to return' }
Argument constraints
Explicit arguments
obj.should_receive(:message).with('an argument')
obj.should_receive(:message).with('more_than', 'one_argument')
Argument matchers
obj.should_receive(:message).with(anything())
obj.should_receive(:message).with(an_instance_of(Money))
obj.should_receive(:message).with(hash_including(:a => 'b'))
Regular expressions
obj.should_receive(:message).with(/abc/)
Counts
obj.should_receive(:message).once
obj.should_receive(:message).twice
obj.should_receive(:message).exactly(3).times
obj.should_receive(:message).at_least(:once)
obj.should_receive(:message).at_least(:twice)
obj.should_receive(:message).at_least(n).times
obj.should_receive(:message).at_most(:once)
obj.should_receive(:message).at_most(:twice)
obj.should_receive(:message).at_most(n).times
Raising/Throwing
obj.should_receive(:message) { raise "this error" }
obj.should_receive(:message) { throw :this_symbol }
Ordering
obj.should_receive(:one).ordered
obj.should_receive(:two).ordered
Arbitrary handling
obj.should_receive(:message) do |arg1, arg2|
# set expectations about the args in this block
# and set a return value
end
