javascript - 未处理的PromiseRejectionWarning : Unhandled promise rejection (NodeJs, Webdriverio，Selenium)

Question

我试图在成功提交时验证给定网页的标题(文本)。

我的命令:

async confirmSuccessfulSubmission() {
    return $("#contact_reply h1").getText().then((value) => {
        //incorrect text should be:Thank You for your Message!
        expect(value.to.equal("Thank You for your Message!2")); 
    });
}

异常(exception):

UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 3)

正确的标题是:谢谢您的留言!因此，如果标题是:谢谢您的留言!2 测试应该失败(Chai 断言)。

有什么想法吗？

感谢您的帮助

Answer 1

async confirmSuccessfulSubmission() {
  try{
    let value = await $("#contact_reply h1").getText()
    if(value)
       return expect(value).to.equal("Thank You for your Message!2"); 
    return null
  } catch(e) {
    console.log(e)
  }
}
