量角器在页面中找不到选择器

Question

我有这样的代码：

it('should go to summary page without sending the order', async () => {
    stepExecutor.startTimer();
    // redirects, rather than checking logging 
    await stepExecutor.executeStep(loginWithCustomer, {
      name: 'loginWithCustomer',
      description: 'Page: login'
    });
    // 
    await stepExecutor.executeStep(selectFirstSubscription, {
      name: 'selectFirstSubscription',
      description: 'Page: abo first'
    });
});

async function loginWithCustomer() {
  const page = createLoginPage(browser.params.space);
  await page.navigateTo(browser.params.login.url);
  await page.enterLogin(browser.params.login.username, browser.params.login.password);
  await page.redirect(`${browser.baseUrl}${ABO_FIRST_URI}`);
}

async function selectFirstSubscription() {
  const page = new AboFirstPage();
  await page.closeCookieNotification();
  await page.selectFirstSubscription();
}

export class AboFirstPage {
  async selectFirstSubscription() {
    await element(by.css('.button--primary')).click();
  }
}

它给我暴露了一个错误：

- Failed: No element found using locator: By(css selector, .button--primary)

Executed 1 of 1 spec (1 FAILED) in 5 secs.
[18:04:59] I/launcher - 0 instance(s) of WebDriver still running
[18:04:59] I/launcher - chrome #01 failed 1 test(s)
[18:04:59] I/launcher - overall: 1 failed spec(s)
[18:04:59] E/launcher - Process exited with error code 1

但是在它重定向到（函数loginWithCustomer）的页面上，会出现这样的选择器。 和element（by.css（'。button--primary'））返回一个对象： 这段代码有什么问题？

让我们检查等待的问题。将sleep添加到此函数：

async function selectFirstSubscription() {
  const page = new AboFirstPage();
  await page.closeCookieNotification();
  await browser.sleep(5000);
  await page.selectFirstSubscription();
}

如果它可以工作，那么您有等待的问题，在单击元素之前，应添加显式的服务员。例如await ExpectedConditions.elementToBeClickable(element)
