org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element in selenium, java using TestNG

Question

I have a scenario, where page takes me to a screen where it has a message like the functionality is not enabled. hence you are here. Then i need to navigate to the settings page and has to enable it & reload the form to verify the web elements.

Initially everything was fine, second time when i ran the code. i have encountered no such element exception. because the setting was disabled initially, which has been enabled through the automated script and it is enabled now and i can see the form elements. I have to execute the system setting code only when the element is found else i have to skip the code.

I tried below way, but i still get no such element found error

if(driver.findElement(By.id("ViewErrorMessage")) != null) {

      String errorMsg = driver.findElement(By.xpath("//*[@id=\"ctl00_pnlViewErrorMessage\"]")).getText();
  Assert.assertEquals(errorMsg, "Form is disabled, Hence you are here. Enable the form");

      //system setting code

      driver.findElement(By.xpath("//input[@name='btnSignin']")).click();
      Thread.sleep(2000);
      driver.findElement(By.xpath("//img[@id='imgLogo']")).isDisplayed();
}else{

  //code to verify form elements goes here..
}

error is reported at the if condition. when element is not found, i am assuming it has to execute else loop but it always fails at the same point. could anyone please help.

When driver is not able to find the element it throws NoSuchElementFound exception. You can either wrap the findElement in a try catch to see if the element exists or use isEmpty method.

boolean isElementPresent=true;
try
{
   driver.findElement(By.id("ViewErrorMessage"));
}
catch
{
  isElementPresent=false;
}

if(isElementPresent) {

      String errorMsg = driver.findElement(By.xpath("//*[@id=\"ctl00_pnlViewErrorMessage\"]")).getText();
  Assert.assertEquals(errorMsg, "Form is disabled, Hence you are here. Enable the form");

      //system setting code

      driver.findElement(By.xpath("//input[@name='btnSignin']")).click();
      Thread.sleep(2000);
      driver.findElement(By.xpath("//img[@id='imgLogo']")).isDisplayed();
}else{

  //code to verify form elements goes here..
}

Or you could do like

if(!driver.findElements(By.id("ViewErrorMessage")).isEmpty()) {

      String errorMsg = driver.findElement(By.xpath("//*[@id=\"ctl00_pnlViewErrorMessage\"]")).getText();
  Assert.assertEquals(errorMsg, "Form is disabled, Hence you are here. Enable the form");

      //system setting code

      driver.findElement(By.xpath("//input[@name='btnSignin']")).click();
      Thread.sleep(2000);
      driver.findElement(By.xpath("//img[@id='imgLogo']")).isDisplayed();
}else{

  //code to verify form elements goes here..
}

Option1 worked for me, Thanks. option2 didn't work though. isEmpty method was not listed in the available methods for a webelement — Neelima, Nov 27 '19 at 00:42

Please try isDisplayed in if contion, hope this will help:

if(driver.findElement(By.id("ViewErrorMessage").isDisplayed()) {

      String errorMsg = driver.findElement(By.xpath("//*[@id=\"ctl00_pnlViewErrorMessage\"]")).getText();
  Assert.assertEquals(errorMsg, "Form is disabled, Hence you are here. Enable the form");

      //system setting code

      driver.findElement(By.xpath("//input[@name='btnSignin']")).click();
      Thread.sleep(2000);
      driver.findElement(By.xpath("//img[@id='imgLogo']")).isDisplayed();
}else{

  //code to verify form elements goes here..
}

or Use below

String s1 = "Error message";
String s2 = driver.findElement(By.id("ViewErrorMessage").getText());
if(s1 == s2) {

          String errorMsg = driver.findElement(By.xpath("//*[@id=\"ctl00_pnlViewErrorMessage\"]")).getText();
      Assert.assertEquals(errorMsg, "Form is disabled, Hence you are here. Enable the form");

          //system setting code

          driver.findElement(By.xpath("//input[@name='btnSignin']")).click();
          Thread.sleep(2000);
          driver.findElement(By.xpath("//img[@id='imgLogo']")).isDisplayed();
    }else{

      //code to verify form elements goes here..
    }

Thanks for your time Mahesh, i tried both the ways but the error still exists: nosuchelementexception — Neelima, Nov 27 '19 at 00:49
