How can I verify Error Message on a webpage using Selenium Webdriver?
We can verify error messages on a webpage using Selenium webdriver using the Assertion. In case, the actual and expected values do not match, an Assertion Error is thrown.
Let us try to verify the highlighted error message.
Example
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import java.util.concurrent.TimeUnit;
import org.testng.Assert;
public class VerifyErrorMsg{
public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver",
"C:\Users\ghs6kor\Desktop\Java\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
//implicit wait
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
//URL launch
driver.get("https://www.linkedin.com/");
// identify element
WebElement l = driver.findElement(By.id("session_key"));
l.sendKeys("abc");
WebElement t = driver.findElement(By.className("sign-in-form__submit-button"));
t.click();
//expected error text
String exp = "Please enter a valid email address or mobile number.";
//identify actual error message
WebElement m = driver.findElement(By.className("alert-content"));
String act = m.getText();
System.out.println("Error message is: "+ act);
//verify error message with Assertion
Assert.assertEquals(exp, act);
driver.quit();
}
}Output
