问如果我正在测试一个rspec扩展，如何抑制测试失败的结果？

EN

require 'rspec-let-and-after-extension'

RSpec.describe "let(...).and_after" do
  it 'is called if the `let` is invoked even if the example fails' do
    call_order = []

    RSpec.describe do
      let(:foo) { }.and_after { call_order << :and_after }
      it { foo; call_order << :example; raise 'failed!' }
    end.run

    expect(call_order).to eq [:example, :and_after]
  end
end
