Question

我刚刚开始尝试 codeceptjs ，看看我们是否可以在项目中使用它。它看起来非常有用，但是我一直遇到一个讨厌的错误，我无法指出：-（

谁知道我该怎么做才能摆脱下面的错误？我在MBP上使用量角器助手运行codeceptjs。

错误：

"after each" hook: finalize codeceptjs for "test something | {"page":"Test pagina CARDS-CC"}":
     no such alert
  (Session info: chrome=67.0.3396.87)
  (Driver info: chromedriver=2.40.565386 (45a059dc425e08165f9a10324bd1380cc13ca363),platform=Mac OS X 10.13.5 x86_64)

我也是CodeceptJS的新手，也发现了相同的错误。您可以在命令中添加--verbose开关以查看错误堆栈跟踪。

问题可能取决于您的帮助者，但就我而言，似乎Protractor会自动为每个执行的测试用例预测任何警报弹出窗口，并尝试自动将其关闭。如果未找到警报，则在异常字符串包含no alert open的情况下，它仅捕获引发的异常。问题在于检查错误消息。它似乎不匹配，因此引发了异常并且没有被跳过。

我的错误消息：

我查看了错误发生的源代码，发现预期的错误消息与实际的错误消息之间不匹配。

实际例外： NoSuchAlertError: no such alert

预期的异常消息： 'no alert open'

从堆栈跟踪的这一行获得它：

at Protractor.grabPopupText (C:\Users\user\AppData\Roaming\npm\node_modules\codeceptjs-protractor\node_modules\codeceptjs\lib\helper\Protractor.js:1066:52)`

代码：

async grabPopupText() {
    try {
      const dialog = await this.browser.switchTo().alert();

      if (dialog) {
        return dialog.getText();
      }
    } catch (e) {
      if (e.message.indexOf('no alert open') > -1) {
        // Don't throw an error
        return null;
      }
      throw e;
    }
  }

临时解决方法： 我只是在错误消息检查部分添加了no such alert，直到他们修复了该错误。

if (e.message.indexOf('no alert open') > -1 || e.message.indexOf('no such alert') > -1) {
        // Don't throw an error
        return null;
      }

希望这种快速的解决方法有所帮助。
