RSpec matcher?

[jmuheim]

Is there something like this yet?

it { should validate_timeliness_of :birth_date }

Here is a naive RSpec matcher which simply checks whether the validator is present for the respective attribute. It does not check the options or whether there is an if or unless conditional applied to the validation.

RSpec::Matchers.define :validate_timeliness_of do |attribute|
  match do |model|
    model._validators[attribute.to_sym].detect do |validator|
      validator.class == ActiveModel::Validations::TimelinessValidator &&
        validator.attributes.include?(attribute)
    end
  end

  failure_message_for_should do |actual|
    "expect #{attribute} to validate timeliness of"
  end

  failure_message_for_should_not do |actual|
    "expect #{attribute} to not validate timeliness of"
  end
end

I did have such a matcher in earlier versions but I didn't find there is much value in such a matcher. But please create your own gem (e.g validates_timeliness-rpec) to explore it.
