RSpec soft failure for pending test cases

Recently, I’ve been playing with RSpec to run RDFa test cases. The suite has accepted and unreviewed test cases. My general way of testing is to parse the suite, and run each test through a generated spec as follows:

test_cases.each do |tc|
  specify "test #{tc.name}" do
    tc.run_test do |input|
      RdfaParser::RdfaParser.new.parse(input, tc.informationResourceInput)
    end
  end
end

The problem is, some tests are pending, so that a failure should be soft, and not hard. The way to do this is to catch Spec::Expectations::ExpectationNotMetError. This this, we can modify the above test as follows:

test_cases.each do |tc|
  specify "test #{tc.name}" do
    tc.run_test do |input|
      begin
        RdfaParser::RdfaParser.new.parse(input, tc.informationResourceInput)
      rescue Spec::Expectations::ExpectationNotMetError => e
        if tc.status == "unreviewed
          pending(e.message) {  raise }
        else
          raise
        end
      end
    end
  end
end
