如何在selenium c＃中弹出“来自网页的消息”中点击“确定”？

Question

我有一个应用程序，在点击按钮后，一个名为“来自网页的消息”的弹出窗口显示错误消息。我想单击“确定”按钮并验证错误消息。 我尝试了以下代码

public void clickButtonWithOk()
    {
        try
        {
            Thread.Sleep(Convert.ToInt32(GlobalVariables.WaitTime.ToString()) * 1000);

            // Get element at runtime
            inputData = "45";
            waitForElementDisplayed();
            int runTimeObjectSize = driver.FindElements(getApplicationObject(currentObjectName, currentObjectType, currentObjectUniqueId)).Count;
            if (runTimeObjectSize == 0)
                STEPLogger.logmessage(STEPLogger.FAIL, "FAILED to click button " + currentObjectName + " Object NOT Found");
            else
            {

                IWebElement element = driver.FindElements(getApplicationObject(currentObjectName, currentObjectType, currentObjectUniqueId))[0];
                IJavaScriptExecutor executor = (IJavaScriptExecutor)driver;

                executor.ExecuteScript("window.confirm = function(msg){return true;};");
                executor.ExecuteScript("arguments[0].click();", element);

                STEPLogger.logmessage(STEPLogger.PASS, "SUCCESSFULLY clicked on button " + currentObjectName);
            }
        }
        catch (Exception oException)
        {
            STEPLogger.logmessage(STEPLogger.FAIL, "FAILED clickButton:" + oException.ToString());
        }
    } // End of CLICKBUTTONWithOk
