Implements the methods needed for a pure test double. RSpec::Mocks::Mock includes this module, and it is provided for cases where you want a pure test double without subclassing RSpec::Mocks::Mock.
Extends the TestDouble module onto the given object and initializes it as a test double.
@example
module = Module.new RSpec::Mocks::TestDouble.extend_onto(module, "MyMixin", :foo => "bar") module.foo #=> "bar"
# File lib/rspec/mocks/test_double.rb, line 17 17: def self.extend_onto(object, name=nil, stubs_and_options={}) 18: object.extend self 19: object.send(:__initialize_as_test_double, name, stubs_and_options) 20: end
Creates a new test double with a `name` (that will be used in error messages only)
# File lib/rspec/mocks/test_double.rb, line 24 24: def initialize(name=nil, stubs_and_options={}) 25: __initialize_as_test_double(name, stubs_and_options) 26: end
This allows for comparing the mock to other objects that proxy such as ActiveRecords belongs_to proxy objects. By making the other object run the comparison, we’re sure the call gets delegated to the proxy target.
