Test groups in Selenium Java - Test Execution Trace

Test Overview

This test demonstrates how to use test groups in Selenium with TestNG. It runs a login test that belongs to the 'smoke' group and verifies successful login by checking the page title.

Test Code - TestNG

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.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class LoginTest {
    WebDriver driver;

    @BeforeClass
    public void setUp() {
        driver = new ChromeDriver();
        driver.manage().window().maximize();
    }

    @Test(groups = {"smoke"})
    public void testValidLogin() {
        driver.get("https://example.com/login");
        WebElement username = driver.findElement(By.id("username"));
        WebElement password = driver.findElement(By.id("password"));
        WebElement loginButton = driver.findElement(By.id("loginBtn"));

        username.sendKeys("user1");
        password.sendKeys("pass123");
        loginButton.click();

        String expectedTitle = "Dashboard";
        String actualTitle = driver.getTitle();
        Assert.assertEquals(actualTitle, expectedTitle, "Page title should be Dashboard after login");
    }

    @AfterClass
    public void tearDown() {
        if (driver != null) {
            driver.quit();
        }
    }
}

Execution Trace - 10 Steps

Step	Action	System State	Assertion	Result
1	Test starts	TestNG initializes and prepares to run tests	-	PASS
2	Browser opens Chrome and maximizes window	Chrome browser window is open and maximized	-	PASS
3	Navigates to https://example.com/login	Login page is loaded with username, password fields and login button	-	PASS
4	Finds username input field by id 'username'	Username input field is located	-	PASS
5	Finds password input field by id 'password'	Password input field is located	-	PASS
6	Finds login button by id 'loginBtn'	Login button is located	-	PASS
7	Enters username 'user1' and password 'pass123'	Username and password fields are filled	-	PASS
8	Clicks login button	Login form submitted, page navigates to dashboard	-	PASS
9	Checks page title equals 'Dashboard'	Dashboard page is displayed	Assert.assertEquals(actualTitle, expectedTitle)	PASS
10	Test ends and browser closes	Browser window is closed	-	PASS

Failure Scenario

Failing Condition: Page title after login is not 'Dashboard' due to failed login or navigation error

Execution Trace Quiz - 3 Questions

Which step verifies that the login was successful?

A Entering username and password

B Checking the page title equals 'Dashboard'

C Clicking the login button

D Opening the browser window

Key Result

Using test groups helps organize tests and run only relevant subsets, improving test suite efficiency and management.
