### Basics
# create a double
obj = double()
# expect a message
obj.should_receive(:message)
# specify a return value
obj.should_receive(:message) { :value }
obj.should_receive(:message => :value)
obj.should_receive(:message).and_return(:value)
These forms are somewhat interchangeable. The difference is that the
block contents are evaluated lazily when the `obj` receives the
`message` message, whereas the others are evaluated as they are read.
### Fake implementation
obj.should_receive(:message) do |arg1, arg2|
# set expectations about the args in this block
# and set a return value
end
### Raising/Throwing
obj.should_receive(:message).and_raise("this error")
obj.should_receive(:message).and_throw(:this_symbol)
You can also use the block format:
obj.should_receive(:message) { raise "this error" }
obj.should_receive(:message) { throw :this_symbol }
### 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
### Ordering
obj.should_receive(:one).ordered
obj.should_receive(:two).ordered
