关于html：Java / Selenium WebDriver：如果在页面上未找到Webelement，请不要将焦点移至ELSE块

Java/Selenium WebDriver: Focus don't skip to ELSE block if a webelement is not found on page

我正在使用Java开发Selenium WebDriver，在输入无效的用户名和密码时，我需要检查一种情况，应用程序应引发警告消息。如果输入正确的凭据，则不会显示警告消息。我在下面编写了一段代码来验证有关错误登录凭据的警告消息。但是，当我输入有效的详细信息时，我的代码不会跳到else块，而是会说不能识别元素("//*[@class='small-9 small-pull-1 column content']")。

代码：

try {
if (new WebDriverWait(driver, 10).until(ExpectedConditions.textToBePresentInElementLocated(By.xpath("//*[@class='small-9 small-pull-1 column content']"),"No Password Found for"))){

String text = driver.findElement(By.xpath("//*[@class='small-9 small-pull-1 column content']")).getAttribute("innerHTML");
System.out.println(text);

if(text.contentEquals("No Password Found for")){
driver.navigate().refresh();

Assert.fail("Unable to login to application");
}
}

else if(new WebDriverWait(driver, 10).until(ExpectedConditions.textToBePresentInElementLocated(By.xpath("//*[@class='small-9 small-pull-1 column content']"),"Your Online/Mobile Banking User ID has been blocked. Please go to a€?Forgot Passworda€? option to unblock it."))){

String retext = driver.findElement(By.xpath("//*[@class='small-9 small-pull-1 column content']")).getAttribute("innerHTML");

System.out.println(retext);

if(retext.contentEquals("Your Online/Mobile Banking User ID has been blocked. Please go to a€?Forgot Passworda€? option to unblock it.")) {
driver.navigate().refresh();

Assert.fail("Unable to login to application");
}

}

else if (new WebDriverWait(driver, 10).until(ExpectedConditions.textToBePresentInElementLocated(By.xpath("//*[@class='small-9 small-pull-1 column content']"),"Time Out"))){
String timeouttext = driver.findElement(By.xpath("//*[@class='small-9 small-pull-1 column content']")).getAttribute("innerHTML");

if(timeouttext.contentEquals("You have specified an invalid User Name or Password. Please check and try again")){
driver.navigate().refresh();

Assert.fail("Unable to login to application"); }

}

带有失败消息的HTML阻止：

<span class="icon-cancel-thin color-white" messagepopupclose=""></span>
<i class="icon-exclamation-circle">
You have specified an invalid User Name or Password. Please check and try again
No Password Found for

我已经优化了您的代码块，如下所示：

在任何情况下，都必须从try{}块中引出driver.findElement(By.name("submitted")).click();。
导致WebDriverWait出现text无效的用户名或密码。
保留xpath的错误文本无效的用户名或密码。
将getText()替换为getAttribute(" innerHTML")
保持contentEquals()和Assert.fail()逻辑不变。
已删除driver.navigate().refresh();，因为它可能会引发StaleElementReferenceException
如果您的try{}未能收到错误消息，则将显示您的程序将要打印的仪表板。

这是您的工作代码块：
