Instance Method Details

#expect(name, retval, args = []) ⇒ Object

Expect that method name is called, optionally with args, and returns retval.

mock.expect :meaning_of_life, 42
mock.meaning_of_life # => 42

mock.expect :do_something_with, true, [some_obj, true]
mock.do_something_with some_obj, true # => true

args is compared to the expected args using case equality (ie, the ‘===’ method), allowing for less specific expectations.

mock.expect :uses_any_string, true, [String]
mock.uses_any_string 'foo' # => true
mock.verify  # => true

mock.expect :uses_one_string, true, ['foo']
mock.uses_one_string 'bar' # => true
mock.verify  # => raises MockExpectationError
