rspec-will_be_expected

Rspec::WillBeExpected

Designed to prettify one-liners when you have block expectations for subject.

Creates an alias RSpec::Core::MemoizedHelpers.will_be_expected to expect { subject }

Simple to use:

class SimplePrinter
  def initialize
    print 'Printer is ready'
  end
end

This goes to

it { will_be_expected.to output('Printer is ready').to_stdout }

instead of

specify { expect { subject }.to output('Printer is ready').to_stdout }

For more complicated cases:

describe UserFactory do
  subject { UserFactory.create_user }

  it { will_be_expected.to change(User.count).by(1) }
  it { will_be_expected.to output.to_stdout }

  context 'with database issues' do
    it { will_be_expected.to output.to_stderr }
    it { will_be_expected.to raise_error }
  end
end

This change allows to DRY up, prettify and make specs even more readable.
