RSpec documentation

require 'rspec/expectations'

RSpec::Matchers.define :be_a_multiple_of do |expected|
  match do |actual|
    (actual % expected).zero?
  end
  failure_message_for_should do |actual|
    "expected that #{actual} would be a multiple of #{expected}"
  end
  failure_message_for_should_not do |actual|
    "expected that #{actual} would not be a multiple of #{expected}"
  end
  description do
    "be multiple of #{expected}"
  end
end

match failure_message_for_should

match_for_should match_for_should_not

user.permissions.should be(42), 'user does not have administrative rights'

user.should have_administrative_rights

require 'rspec/expectations'

RSpec::Matchers.define :have_administrative_rights do
  match do |thing|
    thing.permissions == 42
  end
  failure_message_for_should do |actual|
    'user does not have administrative rights'
  end
  failure_message_for_should_not do |actual|
    'user has administrative rights'
  end
end
