Test case components (steps, expected, actual) in Testing Fundamentals - Test Execution Trace

Test Overview

This test case checks the login functionality of a website. It verifies that when a user enters valid credentials, they successfully log in and see a welcome message.

Test Code - Selenium

Testing Fundamentals

def test_login_success():
    # Step 1: Open login page
    driver.get('https://example.com/login')

    # Step 2: Enter username
    username_field = driver.find_element(By.ID, 'username')
    username_field.send_keys('validUser')

    # Step 3: Enter password
    password_field = driver.find_element(By.ID, 'password')
    password_field.send_keys('validPass123')

    # Step 4: Click login button
    login_button = driver.find_element(By.ID, 'loginBtn')
    login_button.click()

    # Step 5: Verify welcome message
    welcome_message = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.ID, 'welcomeMsg'))
    )
    assert welcome_message.text == 'Welcome, validUser!', 'Welcome message did not match expected text'
