量角器打字稿错误：WebDriverError：java.net.ConnectException：连接被拒绝：从多选列表中选择值时进行连接

Question

我正在尝试从多选下拉菜单中选择选项，它选择了几个，然后显示错误WebDriverError：java.net.ConnectException：连接被拒绝：connect。

这是我要从yml传递值并逐一检查并单击的功能

async assignViewersToUser(viewsOption: string){
    if (viewsOption !== null) {
        browser.manage().deleteAllCookies();
        await this.viewersDropdown.click();
        var view = viewsOption.split(',');
        for (let i = 0; i < view.length; i++) {
            var viewsList = element.all(by.xpath('.//div[@class="pq-select-menu"]//span[contains(text(), "' + view[i] + '")]/parent::label/input'));
            await viewsList.filter(function (ele) {
                return ele.isDisplayed();
            }).then(async function (viewsList) {
                if (await viewsList[0].isSelected() === true) {
                    console.log(viewsList[0] + ' Case is Already selected');
                } else {
                    await viewsList[0].click();
                }
            });
        }
    } else {
        console.log('No View found against this user');
    }
    await browser.sleep(1000);
}

获取此异常

Answer 1

您的函数存在一些语法问题。使用异步/等待时，几乎所有操作现在都需要手动等待，.then几乎不需要。

注意：请注意，仅当filteredList[0]被硬编码时，您的函数才会始终选择第一个复选框。

您可以尝试以下方法并让我知道吗？

async assignViewersToUser(viewsOption: string){

  //viewsOption should never be null so throw error if it it. Rest of function won't be executed if null
  if (viewsOption === null) throw new Error('viewsOption is null');

  //Need to await deleteAllCookies()
  await browser.manage().deleteAllCookies();
  await this.viewersDropdown.click();

  var view = viewsOption.split(',');
  for (let i = 0; i < view.length; i++) {
    var viewsList = await element.all(by.xpath('.//div[@class="pq-select-menu"]//span[contains(text(), "' + view[i] + '")]/parent::label/input'));

    //No need to use .then when using awaits
    let filteredList = await viewsList.filter(function (ele) {
      return ele.isDisplayed();
    });

    if (await filteredList[0].isSelected() === true) {
      console.log(filteredList[0] + ' Case is Already selected');
    } else {
      await filteredList[0].click();
    }
  };

  await browser.sleep(1000);
}
