Support for the Ruby 2.1 series ended on March 31 2017. See here for details.
All mock objects are an instance of Mock
Expect that method name
is called, optionally with
args
or a blk
, 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 @mock.expect(:do_something_else, true) do |a1, a2| a1 == "buggs" && a2 == :bunny end
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 minitest/mock.rb, line 56 def expect(name, retval, args=[], &blk) if block_given? raise ArgumentError, "args ignored when block given" unless args.empty? @expected_calls[name] << { :retval => retval, :block => blk } else raise ArgumentError, "args must be an array" unless Array === args @expected_calls[name] << { :retval => retval, :args => args } end self end
Verify that all methods were called as expected. Raises
MockExpectationError
if the mock object was not called as
expected.
