TestNG annotations (@Test, @BeforeMethod, @AfterMethod) in Selenium Java - Test Execution Trace

Test Overview

This test uses TestNG annotations to open a browser before each test, check the page title, and close the browser after each test.

Test Code

Selenium Java

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.Test;
import static org.testng.Assert.assertEquals;

public class TestNGAnnotationsExample {
    WebDriver driver;

    @BeforeMethod
    public void setUp() {
        // Set the path to chromedriver executable if needed
        // System.setProperty("webdriver.chrome.driver", "path/to/chromedriver");
        driver = new ChromeDriver();
        driver.get("https://example.com");
    }

    @Test
    public void verifyPageTitle() {
        String title = driver.getTitle();
        assertEquals(title, "Example Domain", "Page title should be 'Example Domain'");
    }

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

Execution Trace - 3 Steps

Step	Action	System State	Assertion	Result
1	BeforeMethod runs: ChromeDriver is initialized and navigates to https://example.com	Browser window opens and loads the Example Domain page	-	PASS
2	Test method runs: Gets the page title	Browser is on Example Domain page	Check that page title equals 'Example Domain'	PASS
3	AfterMethod runs: Browser is closed	Browser window closes	-	PASS

Failure Scenario

Failing Condition: Page title does not match 'Example Domain'

Execution Trace Quiz - 3 Questions

What does the @BeforeMethod annotation do in this test?

A Closes the browser after tests

B Runs the setup code before each test method

C Runs the test method

D Skips the test method

Key Result

Using @BeforeMethod and @AfterMethod ensures each test starts fresh with a new browser and cleans up properly, preventing side effects between tests.
