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 15 def self.extend_onto(object, name=nil, stubs_and_options={}) object.extend self object.send(:__initialize_as_test_double, name, stubs_and_options) 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.
# File lib/rspec/mocks/test_double.rb, line 43 def ==(other) other == __mock_proxy end
@private
# File lib/rspec/mocks/test_double.rb, line 65 def __build_mock_proxy proxy = Proxy.new(self, @name, @options || {}) proxy.as_null_object if null_object? proxy end
Tells the object to respond to all messages. If specific stub values are declared, they'll work as expected. If not, the receiver is returned.
# File lib/rspec/mocks/test_double.rb, line 29 def as_null_object @__null_object = true __mock_proxy.as_null_object end
@private
# File lib/rspec/mocks/test_double.rb, line 48 def inspect "#<#{self.class}:#{sprintf '0x%x', self.object_id} @name=#{@name.inspect}>" end
Returns true if this object has received `as_null_object`
# File lib/rspec/mocks/test_double.rb, line 35 def null_object? @__null_object end
@private
# File lib/rspec/mocks/test_double.rb, line 60 def respond_to?(message, incl_private=false) __mock_proxy.null_object? ? true : super end
@private
# File lib/rspec/mocks/test_double.rb, line 53 def to_s inspect.gsub('<','[').gsub('>',']') end
