[DEPRECATED] Adds test spies to mocha.

Deprecated

Given the introduction of test spies in rspec-mocks, Bourne is unnecessary in new versions of RSpec (> 2.14).

Bourne

Bourne extends mocha to allow detailed tracking and querying of stub and mock invocations. It allows test spies using the have_received rspec matcher and assert_received for Test::Unit. Bourne was extracted from jferris-mocha, a fork of mocha that adds test spies.

Test Spies

Test spies are a form of test double that preserves the normal four-phase unit test order and allows separation of stubbing and verification.

Using a test spy is like using a mocked expectation except that there are two steps:

1. Stub out a method for which you want to verify invocations
2. Use an assertion or matcher to verify that the stub was invoked correctly

Examples

RSpec:

mock.should have_received(:to_s)
Radio.should have_received(:new).with(1041)
radio.should have_received(:volume).with(11).twice
radio.should have_received(:off).never

You also want to configure RSpec to use mocha for mocking:

RSpec.configure do |config|
  config.mock_with :mocha
end

Test::Unit:

assert_received(mock, :to_s)
assert_received(Radio, :new) {|expect| expect.with(1041) }
assert_received(radio, :volume) {|expect| expect.with(11).twice }
assert_received(radio, :off) {|expect| expect.never }

See Mocha::API for more information.
