### Introduction
Argument matchers can be used:
* In stubs to constrain the scope of the stubbed method
obj.stub(:foo).with(:bar) do |arg|
#do something for :bar
end
obj.stub(:foo).with(:baz) do |arg|
#do something for :baz
end
* In expectations to validate the arguments that should be received in a method call
#create a double
obj = double()
#expect a message with given args
obj.should_receive(:message).with('an argument')
If more control is needed, one can use a block
obj.should_receive(:message) do |arg1, arg2|
# set expectations about the args in this block
# and optionally set a return value
end
