Capture Error Message in Selenium

Hello Welcome to Selenium tutorial, in this post we will see how to verify Error Message in Selenium.

Testing is nothing but verification and validation. Mostly in testing we verify title, some error messages , tooltip messages and so on.

To capture error message or simple text as well we can use predefined method called  getText().

getText() method will simply capture the error message or text and will return you a String then you can store in String variable and you can use in other application or you can verify as well.

 

Please refer below youtube video for the same.

 

 

 

Program for Verify  Error Message in Selenium Webdriver

package demo;

import org.openqa.selenium.By;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.Test;

public class TestNaukri {
    
    
@Test
public void TestError()
{
  
// Open browser             
FirefoxDriver driver=new FirefoxDriver();
        
// maximize browser
driver.manage().window().maximize();
        
// Open URL
driver.get("http://www.naukri.com/");
        
// Click on login button
driver.findElement(By.id("p0submit")).click();
        
// This will capture error message
String actual_msg=driver.findElement(By.id("emailId_err")).getText();
    
// Store message in variable
String expect="plz enter valid email";
                
// Here Assert is a class and assertEquals is a method which will compare two values if// both matches it will run fine but in case if does not match then if will throw an 
//exception and fail testcases

// Verify error message
Assert.assertEquals(actual_msg, expect);

    }
}

Output-

Capture Error Message in Selenium
You can use getText() method for capturing simple text messages as well and using above method we can verify the same.

Note- If text does not match then TestNG will throw AssertionError and if we do not use Exception handling then it will simply terminate our application/ program.

    I have pasted the code to help others as now the naukri site has changed little bit and the above code may not work

    String str=”http://www.naukri.com”;

    drv.get(str);

    WebElement lgnBtn1=drv.findElement(By.linkText(“Login”));

    lgnBtn1.click();

    WebElement lgnBtn2=drv.findElement(By.xpath(“//button[@value=’Login’]”));

    lgnBtn2.click();

    WebElement lgnBtn3=drv.findElement(By.id(“eLogin_err”));
    WebElement lgnBtn4=drv.findElement(By.id(“pLogin_err”));

    Assert.assertEquals(lgnBtn3.getText(),”Please enter your Email ID”);
    Assert.assertEquals(lgnBtn4.getText(),”Please enter your Password”);
    Thread.sleep(10000);
    WebElement lgnBtn5=drv.findElement(By.id(“fLogin_err”));

    System.out.println(“There is one more error on the screen :- ” + lgnBtn5.getText());
