#after_call(&after_call_proc) ⇒ Object
Double#after_call creates a callback that occurs after call is called.
-
#implemented_by(implementation) ⇒ Object
Double#implemented_by sets the implementation of the Double.

-
#ordered(&return_value_block) ⇒ Object
(also: #then)
Double#ordered sets the Double to have an ordered expectation.
-
#returns(*args, &implementation) ⇒ Object
Double#returns accepts an argument value or a block.
-
#verbose(&after_call_proc) ⇒ Object
Double#verbose sets the Double to print out each method call it receives.

-
#yields(*args, &return_value_block) ⇒ Object
Double#yields sets the Double to invoke a passed in block when the Double is called.
Instance Method Details
#after_call(&after_call_proc) ⇒ Object
Double#after_call creates a callback that occurs after call is called. The passed in block receives the return value of the Double being called. An Expection will be raised if no block is passed in.

subject.method_name # return_value
This feature is built into proxies.

#implemented_by(implementation) ⇒ Object
Double#implemented_by sets the implementation of the Double. This method takes a Proc or a Method. Passing in a Method allows the Double to accept blocks.

#returns(*args, &implementation) ⇒ Object
Double#returns accepts an argument value or a block. It will raise an ArgumentError if both are passed in.
Passing in a block causes Double to return the return value of the passed in block.
Passing in an argument causes Double to return the argument.
