E2E Testing Skill

Purpose

Test complete user workflows and UI interactions using Selenium/Playwright.

When to Use

• ✅ Testing user registration/login flows

• ✅ Testing complex multi-step workflows

• ✅ Testing UI rendering and interactions

• ✅ Cross-browser compatibility testing

Selenium WebDriver Pattern

@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = ApplicationContext.class) public class LoginE2ETest { private WebDriver driver;

@Before
public void setup() {
    driver = new ChromeDriver();
}

@Test
public void shouldLoginSuccessfully() {
    driver.get("http://localhost:8080/login");
    driver.findElement(By.id("username")).sendKeys("testuser");
    driver.findElement(By.id("password")).sendKeys("password");
    driver.findElement(By.id("login-btn")).click();
    
    assertThat(driver.getCurrentUrl()).contains("/dashboard");
}

}

Page Object Model

public class LoginPage { private WebDriver driver;

@FindBy(id = "username")
private WebElement usernameField;

@FindBy(id = "password")
private WebElement passwordField;

@FindBy(id = "login-btn")
private WebElement loginButton;

public void login(String username, String password) {
    usernameField.sendKeys(username);
    passwordField.sendKeys(password);
    loginButton.click();
}

}
