Question

我已经用Google搜索了几个小时，而且我非常难以让我的UI测试专注于弹出窗口。在这个阶段，我很乐意只需点击＆＃34; PayBill＆＃34;，等待弹出窗口（立即加载），然后点击取消。

我的代码的最新版本为：

paybillButton.click();
browser.sleep(500);

browser.getAllWindowHandles().then(function (handles) {
  newWindowHandle = handles[1];
  browser.switchTo().window(newWindowHandle).then(function () {
    cancelButton.click();
  });
});

但它在browser.switchTo()和.window(newWindowHandle).then ...

之间不断失败

错误：

Failed: null value in entry: handle=null
WebDriverError: null value in entry: handle=null
    at Object.checkLegacyResponse (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/error.js:505:15)
    at parseHttpResponse (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/http.js:509:13)

    at TargetLocator.window (/usr/local/lib/node_modules/protractor/node_modules/selenium-webdriver/lib/webdriver.js:1755:25)

我还尝试了Failed: null value in entry: name=null error while switching Popup window ...

中的以下代码

function windowCount(count) {
  return function () {
    return browser.getAllWindowHandles().then(function (handles) {
      return handles.length >= count;
    });
  };
};
browser.wait(windowCount(2), 10000);

browser.getAllWindowHandles().then(function (handles) {
  browser.switchTo().window(handles[1]);
  cancelButton.click();
});

但那会返回这个错误：

switchTo方法是selenium-webdriver switchTo方法的包装器。 switchTo方法返回TargetLocator对象，TargetLocator对象没有window方法。正确的方法是使用frame method。

browser.getAllWindowHandles().then((handles) => {
  let newWindowHandle = handles[1];
  browser.switchTo().frame(newWindowHandle).then(() => {
    cancelButton.click();
  });
});

使用Protractor专注于angular4弹出窗口
