All mock objects are an instance of Mock
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 '===' operator), 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
# File lib/minitest/mock.rb, line 47 def expect(name, retval, args=[]) @expected_calls[name] = { :retval => retval, :args => args } self end
Verify that all methods were called as expected. Raises MockExpectationError if the mock object was not called as expected.
# File lib/minitest/mock.rb, line 57 def verify @expected_calls.each_key do |name| expected = @expected_calls[name] msg1 = "expected #{name}, #{expected.inspect}" msg2 = "#{msg1}, got #{@actual_calls[name].inspect}" raise MockExpectationError, msg2 if @actual_calls.has_key? name and not @actual_calls[name].include?(expected) raise MockExpectationError, msg1 unless @actual_calls.has_key? name and @actual_calls[name].include?(expected) end true end
