Feature: define matcher outside rspec
In order to express my domain clearly in my code examples
As a non-rspec user
I want a shortcut to define custom matchers
Scenario: define a matcher with default messages
Given a file named "test_multiples.rb" with:
"""
require 'test/unit'
require 'spec/expectations'
Spec::Matchers.define :be_a_multiple_of do |expected|
match do |actual|
actual % expected == 0
end
end
class Test::Unit::TestCase
include Spec::Matchers
end
class TestMultiples < Test::Unit::TestCase
def test_9_should_be_a_multiple_of_3
9.should be_a_multiple_of(3)
end
def test_9_should_be_a_multiple_of_4
9.should be_a_multiple_of(4)
end
end
"""
When I run "ruby test_multiples.rb"
Then the exit code should be 256
And the stdout should include "expected 9 to be a multiple of 4"
