木偶拒绝拦截第一个请求？

Question

在拦截请求时，只有第一个之后的请求才会受到影响。 我认为这是因为如果这样我不愿意这样做。 我试着等待domcontent加载，但是那也不起作用。

describe('index', () => {
  let page;
  let testData;
  beforeAll(async () => {
    jest.setTimeout(30000);
    const browser = await puppeteer.launch({
      headless: false,
      slowMo: 100,
      args: ['--windows-size=1920,1080']
    });
    testData = {
      page: 1,
      pages: 7,
      tv_shows: [
        {
          name: 'Star Wars:The Clone Wars'
        }
      ]
    };
    page = await browser.newPage();
    await page.goto('http://localhost:1234/');
    await page.setRequestInterception(true);
    await page.on('request', request => {
      request.respond({
        content: 'application/json',
        headers: { 'Access-Control-Allow-Origin': '*' },
        body: JSON.stringify(testData)
      });
    });
  });
  describe('searching for job', () => {
    let showCard;
    beforeAll(async () => {
      await page.waitForSelector('#search-form');
      await page.type('input[name=title]', 'star wars');
      await page.$eval('#submit-btn', btn => btn.click());
      showCard = await page.waitForSelector('.card');
    });
    it('element with class showCard should exist', () => {
      expect(showCard).toBeTruthy();
    });
  });
});
