量角器在定位元素时不一致。如何解决定位器问题

Question

量角器新手和运行问题。任何帮助是极大的赞赏！ 1.量角器有时定位元素有时不起作用

    public async clickForgetPasswordLink() {
    let expectedValue  = "Forgot Password";
    let link = await element(by.linkText('Forgot Password?'));
    await browser.wait(until.visibilityOf(link),
        TIMEOUT_MILLIS, 'Unable to locate forgot password link...').then(()=>{
         link.click();
    })
   // await link.click();
    let emailText = link.getAttribute("aria-label");
    await emailText.then((text) => {
        logger.info("Getting forgot password link value:" + text);
        expect(text).toEqual(expectedValue);
        browser.driver.sleep(2000);
    });

}

2。我无法找出 StaleElementError 问题的根本原因。在第二个套件中，我正在复制粘贴相同的代码，但错误仅针对第二个套件而不是第一个套件

Answer 1

stale element 表示量角器看到元素。所以它确实找到了它。

当您尝试 await 对多个元素 (20+) 执行操作时，就会出现陈旧元素，例如 await element.all().getText() 因此请找到执行此操作的位置并找出解决方法。

您的代码片段中的代码本来可以更具可读性

public async clickForgetPasswordLink() {
  let expectedValue  = "Forgot Password";
  let link = element(by.linkText('Forgot Password?'));

  await browser.wait(
    until.visibilityOf(link),
    TIMEOUT_MILLIS, 
    'Unable to locate forgot password link...'
  );
  await link.click();

  let emailText = await link.getAttribute("aria-label");

  logger.info("Getting forgot password link value:" + emailText);
  expect(emailText).toEqual(expectedValue);
  await browser.driver.sleep(2000);
}

Answer 2

 public async clickForgetPasswordLink() {
        let expectedValue  = "Forgot Password";
        try {
            let link = await element(by.linkText('Forgot Password?'));
            await browser.wait(await until.elementToBeClickable(link),
                TIMEOUT_MILLIS, 'Unable to locate forgot password link...').then(()=>{
                browser.driver.sleep(2000);
            });
            await link.getAttribute("aria-label").then((text) => {
                logger.info("Getting forgot password link value:" + text);
                expect(text).toEqual(expectedValue);
            });
            await link.click();
            browser.driver.sleep(2000);
        }catch (e) {logger.error("Exception error caught" + e); }
