处理Selenium Python自动化时出错

Question

我正在用Selenium创建一个自动化脚本，以便能够在我的公司使用的网站上创建用户帐户。该程序从active目录中提取所有用户信息，并通过selenium传递信息以创建帐户。如果创建了一个重复的帐户，网站将抛出一个错误。当它这样做时，我希望selenium能够识别错误，并在用户名的末尾添加一个数字，如果它不抛出一个错误，我希望它忽略并继续。我试着用IF trying语句来做这件事。我正在运行的问题是，当错误初始化时，包含错误的HTML元素总是可见的，只是HTML中的一个小变化。我尝试编写XPATH以捕获更改，但始终得到一个TimeoutException错误。我在下面添加了所有脚本，以及在抛出错误之前和抛出错误之后显示的两个HTML元素。如果您对处理错误的更好方法有任何建议，也将受到极大的赞赏。

抛出前错误的HTML

<div class="error-section ng-hide" ng-show="hasErrors">
        <button class="close" ng-click="clearErrors()"></button>
        <p>Sorry, something unexpected happened. Please try again.</p>
        <ul class="nostyle">
            <!-- ngRepeat: error in errorMessages -->
        </ul>
    </div>

抛出错误的HTML

<div class="error-section" ng-show="hasErrors">
        <button class="close" ng-click="clearErrors()"></button>
        <p>Sorry, something unexpected happened. Please try again.</p>
        <ul class="nostyle">
            <!-- ngRepeat: error in errorMessages --><li ng-repeat="error in errorMessages" class="ng-binding ng-scope">Code: 102000890</li><!-- end ngRepeat: error in errorMessages --><li ng-repeat="error in errorMessages" class="ng-binding ng-scope">FaultCode: InvalidData</li><!-- end ngRepeat: error in errorMessages --><li ng-repeat="error in errorMessages" class="ng-binding ng-scope">Error: 102000890 - Login Id is already in use. Please create a different login Id.</li><!-- end ngRepeat: error in errorMessages --><li ng-repeat="error in errorMessages" class="ng-binding ng-scope">Details: </li><!-- end ngRepeat: error in errorMessages -->
        </ul>
    </div>

要处理可能的错误消息，可以将单击Close按钮封装在try-except{}块中，从而为诱导WebDriverWait，您可以使用以下任何一个

使用

• 的CSS_SELECTOR：

尝试:WebDriverWait(驱动程序，WebDriverWait打印(“关闭错误消息”)，但TimeoutException: print(“无错误消息”)除外

使用XPATH的

• ：

尝试:WebDriverWait(驱动程序，WebDriverWait "//button@class='close‘并以(@ng-click，’clearErrors‘“)开头).click()打印(”关闭错误消息“)，但TimeoutException: print(”无错误消息“)除外
