Method: Mocha::ObjectMethods#stubs

Defined in:
lib/mocha/object.rb

#stubs(method_name_or_hash) ⇒ Object

:call-seq: stubs(method_name) -> expectation

stubs(method_names_vs_return_values) -> last expectation

Adds an expectation that a method identified by method_name Symbol may be called any number of times with any parameters. Returns the new expectation which can be further modified by methods on Mocha::Expectation.

product = Product.new
product.stubs(:save).returns(true)
assert_equal true, product.save

The original implementation of Product#save is replaced temporarily.

The original implementation of Product#save is restored at the end of the test.

If method_names_vs_return_values is a Hash, an expectation will be set up for each entry using the key as method_name and value as return_value.

product = Product.new
product.stubs(:valid? => true, :save => true)

# exactly equivalent to

product = Product.new
product.stubs(:valid?).returns(true)
product.stubs(:save).returns(true)
