如何断言窗体的值。使用stencil的Puppeter e2e测试提交()

我有一个针对stenciljs组件的e2e测试,我想在其中断言提交到表单的值。我得到了一个类似于比赛条件的错误,但我不确定它可能在哪里。我的测试是这样的:

it('TEST THE VAUE of FORM SUBMISSION', async () => {
  //arrange
  const page = await newE2EPage();

  // ---- SET UP REQUEST HANDLER ----
  await page.setRequestInterception(true);
  page.on('request', (request) => {
    if (request.url() === 'http://test.com') {
      request.respond({
        content: 'application/json',
        headers: { 'Access-Control-Allow-Origin': '*' },
        status: 200,
        body: request.postData(),
    });
    } else {
      request.continue();
    }
  });

  // ---- SET UP FORM ELEMENT ----
  await page.setContent(`
    <form action="http://test.com" method="POST" >
      <sjs-checkbox id="unchecked" name="checked" value="no"></sjs-checkbox>
      <sjs-checkbox id="checked" name="checked" value ="yes" checked></sjs-checkbox>
    </form>`);  
  
  //act
  // INVOKE FORM SUBMIT
  const response = await page.evaluate(() => {
    const form = document.querySelector('form');
    form.submit();
  });

  //assert
  
  expect(await response).toBeDefined();
});

下面是错误消息:

Cannot log after tests are done. Did you forget to wait for something async in your test?
    Attempted to log "requestfailed http://localhost:3333/~dev-server".

abds-checkbox › TEST THE VAUE of FORM SUBMISSION
    Request is already handled!

同样,这似乎是一个比赛条件,但我不确定在做出断言之前我应该等待什么。

有人知道如何断言表单的值吗。提交()使用stencil的傀儡e2e测试?
