使用selenium Web驱动程序验证错误消息

Question

I want to verify the error message displaying, after login failed. I am always getting "Test Case Failed" from which I have tried.

I want to verify the text with "Invalid username or password". below are the codes I tried.

This is the html code.

<div id="statusMsg">
  <div class="alert in fade alert-error" style="opacity: 1;">
    <a class="close" data-dismiss="alert">×</a>
      Invalid username or password
  </div>
</div>

These is the code I tried.

String actualMsg=driver2.findElement(By.xpath("//div[@id='statusMsg']/div")).getText()
String errorMsg= "× Invalid username or password";

if(actualError.equals(errorMsg)) {
        System.out.println("Test Case Passed");
    }else{
        System.out.println("Test Case Failed");
    };

The output is always "Test Case Failed".

Is There a way to fix this?

Answer 1

To extract the text Invalid username or password you have to reach to the <div> tag as follows :

String actualMsg = driver2.findElement(By.xpath("//div[@id='statusMsg']/div[@class='alert in fade alert-error']")).getAttribute("innerHTML");

Next your expected error message is :

String errorMsg = "× Invalid username or password";

As x is within <a> tag and Invalid username or password is within <div> tag the validation process will need a bit of String manipulation. To make the validation simpler you can reduce the expected error message as follows :

String errorMsg = "Invalid username or password";

Now you can use the following code block to verify if the actualMsg contains errorMsg as follows :

if(actualMsg.contains(errorMsg)) 
{
    System.out.println("Test Case Passed");
}else
{
    System.out.println("Test Case Failed");
};

Answer 2

Inside div you only have text "Invalid username or password", but you are verifying "× Invalid username or password". First print text from String actualMsg and then put correct errorMsg.

String actualMsg = driver2.findElement(By.xpath("//div[@id='statusMsg']/div")).getText()
String errorMsg= "Invalid username or password";

if(actualError.equals(errorMsg)) {
        System.out.println("Test Case Passed");
    }else{
        System.out.println("Test Case Failed");
    }
