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 "rspec/expectations"
require "test/unit"
RSpec::Matchers.define :be_a_multiple_of do |expected|
match do |actual|
actual % expected == 0
end
end
class Test::Unit::TestCase
include RSpec::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 status should not be 0
And I should see "expected 9 to be a multiple of 4"
And I should see "2 tests, 0 assertions, 0 failures, 1 errors"
