Retry analyzer for failures in Selenium Java - Test Execution Trace

Test Overview

This test demonstrates how a retry analyzer works in Selenium with Java. It retries a failed test once before marking it as failed, verifying that the retry logic triggers on failure.

Test Code - TestNG with Selenium WebDriver

Selenium Java

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class RetryAnalyzerExample {

    WebDriver driver;

    @BeforeClass
    public void setup() {
        driver = new ChromeDriver();
        driver.get("https://example.com/login");
    }

    @Test(retryAnalyzer = Retry.class)
    public void testLogin() {
        WebElement username = driver.findElement(By.id("username"));
        WebElement password = driver.findElement(By.id("password"));
        WebElement loginButton = driver.findElement(By.id("loginBtn"));

        username.sendKeys("wrongUser");
        password.sendKeys("wrongPass");
        loginButton.click();

        WebElement errorMsg = driver.findElement(By.id("errorMsg"));
        Assert.assertTrue(errorMsg.isDisplayed(), "Error message should be displayed for invalid login");
    }

    @AfterClass
    public void teardown() {
        driver.quit();
    }

    public static class Retry implements IRetryAnalyzer {
        private int retryCount = 0;
        private static final int maxRetryCount = 1;

        @Override
        public boolean retry(ITestResult result) {
            if (retryCount < maxRetryCount) {
                retryCount++;
                return true;
            }
            return false;
        }
    }
}

Execution Trace - 9 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser opened at https://example.com/login page	-	PASS
2	Find username, password fields and login button	Login form elements are located on the page	-	PASS
3	Enter invalid username and password, then click login	Login form submitted with wrong credentials	-	PASS
4	Find error message element on page	Error message element located	Check if error message is displayed	FAIL
5	Retry analyzer triggers retry of testLogin	Test restarts: browser still open at login page	-	PASS
6	Repeat steps: find elements, enter invalid credentials, click login	Login form submitted again with wrong credentials	-	PASS
7	Find error message element again	Error message element located	Check if error message is displayed	PASS
8	Test completes successfully after retry	Test marked as pass	-	PASS
9	Browser closes	Browser closed	-	PASS

Failure Scenario

Failing Condition: Error message element is not found or not displayed after retry

Execution Trace Quiz - 3 Questions

What does the retry analyzer do when the test fails the first time?

A It retries the test once before marking it failed

B It immediately marks the test as failed without retry

C It retries the test infinitely until it passes

D It skips the test after failure

Key Result

Using a retry analyzer helps reduce false negatives by rerunning failed tests automatically once, improving test reliability without manual intervention.
