Methods added to all objects to allow mocking and stubbing on real (i.e. non-mock) objects.
Both {expects} and {stubs} return an {Expectation} which can be further modified by methods on {Expectation}.
Adds an expectation that the specified method must be called exactly once with any parameters.
The original implementation of the method is replaced during the test and then restored at the end of the test.
@param [Symbol,String] method_name name of expected method @param [Hash] expected_methods_vs_return_values expected method name symbols as keys and corresponding return values as values - these expectations are setup as if {expects} were called multiple times.
@overload def expects(method_name) @overload def expects(expected_methods_vs_return_values) @return [Expectation] last-built expectation which can be further modified by methods on {Expectation}. @raise [StubbingError] if attempting to stub method which is not allowed.
@example Setting up an expectation on a non-mock object.
product = Product.new product.expects(:save).returns(true) assert_equal true, product.save
@example Setting up multiple expectations on a non-mock object.
product = Product.new product.expects(:valid? => true, :save => true) # exactly equivalent to product = Product.new product.expects(:valid?).returns(true) product.expects(:save).returns(true)

Removes the specified stubbed methods (added by calls to {expects} or {stubs}) and all expectations associated with them.
Restores the original behaviour of the methods before they were stubbed.
WARNING: If you {unstub} a method which still has unsatisfied expectations, you may be removing the only way those expectations can be satisfied. Use {unstub} with care.
@param [Array<Symbol>] method_names names of methods to unstub.
@example Stubbing and unstubbing a method on a real (non-mock) object.
multiplier = Multiplier.new multiplier.double(2) # => 4 multiplier.stubs(:double).raises # new behaviour defined multiplier.double(2) # => raises exception multiplier.unstub(:double) # original behaviour restored multiplier.double(2) # => 4
@example Unstubbing multiple methods on a real (non-mock) object.
multiplier.unstub(:double, :triple) # exactly equivalent to multiplier.unstub(:double) multiplier.unstub(:triple)
