Inconvertible specs can be solved by including RSpec::Matchers in the appropriate context

[myronmarston]

Your README mentions some things that can't be converted, because expect isn't available everywhere. For cases like these, the RSpec::Matchers module can be included or extended to make it available to that context.

For example, in the example in the README, this would work:

  class MyAwesomeTestRunner
    include RSpec::Matchers

    def run
      expect(1).to eq(1)
    end
  end

Thanks. I'll add some descriptions to the README.
