javascript - 在 React 测试库中发现多个元素错误

Question

我在查询时遇到问题，我正在尝试获取两个 radio 输入，其中一个没有任何问题，但另一个 React 测试库抛出错误:It Found multiple elements with the role "radio" and name /to/i:查询

test('Render form with default items', () => {
  const handleUpdateValue = jest.fn();
  const handleNextStep = jest.fn();
  render(
    <Form
      handleNextStep={handleNextStep}
      updateValue={handleUpdateValue}
      transferFundsValues={{}}
    />
  );

  const amountInput = screen.getByLabelText(/amount/i);
  const fromRadio = screen.getByLabelText(/from/i);
  const toRadio = screen.getByLabelText(/to/i);
  const messageInput = screen.getByLabelText(/message/i);

  const continueButton = screen.getByRole('button', { name: /continue/i });
  const cancelButton = screen.getByRole('button', { name: /cancel/i });

  // If no value has been entered to the inputs, the continue button must be
  // disabled
  expect(continueButton).toBeDisabled();
});

html结构

<label for="transferFunds_from" class="ant-form-item-required" title="From">From</label>
<input id="transferFunds_from" type="radio" class="ant-radio-button-input" value="">

<label for="transferFunds_to" class="ant-form-item-required" title="To">To</label>
<input id="transferFunds_to" type="radio" class="ant-radio-button-input" value="">

RTL 引发的错误

 TestingLibraryElementError: Found multiple elements with the role "radio" and name `/to/i`

    Here are the matching elements:

    <input
      class="ant-radio-button-input"
      id="transferFunds_from"
      type="radio"
      value=""
    />

    <input
      class="ant-radio-button-input"
      id="transferFunds_to"
      type="radio"
      value=""
    />

我不知道是我在 HTML 结构中做错了什么，还是 React 测试库错误。

只是一个快速提示，如果您有多个匹配元素，您可以这样查询:
HTML:

<a href="/my-element">My element</a>
<a href="/my-element">My element</a>

测试:

test('renders my element', () => {
  let link = screen.getAllByText('My element')[0] as HTMLAnchorElement;
  expect(link.href).toContain('/my-element');
});
