Verify login functionality on BrowserStack cloud platform

Preconditions (3)

Step 1: Open remote browser session on BrowserStack with Windows 10 and Chrome latest

Step 2: Navigate to 'https://example.testapp.com/login'

Step 3: Enter 'testuser@example.com' in the email input field with id 'email'

Step 4: Enter 'TestPass123' in the password input field with id 'password'

Step 5: Click the login button with id 'loginBtn'

Step 6: Wait until the dashboard page loads and URL contains '/dashboard'

✅ Expected Result: User is successfully logged in and redirected to the dashboard page with URL containing '/dashboard'

Automation Requirements - Selenium WebDriver with Python

Assertions Needed:

Verify current URL contains '/dashboard' after login

Verify login button is clickable before clicking

Verify email and password fields are present before input

Best Practices:

Use explicit waits to wait for elements and page load

Use remote WebDriver with desired capabilities for BrowserStack

Use try-except blocks to handle exceptions gracefully

Close the remote browser session after test

Automated Solution

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# BrowserStack credentials and URL
BROWSERSTACK_USERNAME = 'your_username'
BROWSERSTACK_ACCESS_KEY = 'your_access_key'
remote_url = f'https://{BROWSERSTACK_USERNAME}:{BROWSERSTACK_ACCESS_KEY}@hub-cloud.browserstack.com/wd/hub'

# Desired capabilities for Windows 10 and Chrome latest
desired_cap = {
    'os': 'Windows',
    'os_version': '10',
    'browserName': 'Chrome',
    'browser_version': 'latest',
    'name': 'Login Test on BrowserStack'
}

try:
    driver = webdriver.Remote(
        command_executor=remote_url,
        desired_capabilities=desired_cap
    )

    wait = WebDriverWait(driver, 15)

    # Navigate to login page
    driver.get('https://example.testapp.com/login')

    # Wait for email field and enter email
    email_field = wait.until(EC.presence_of_element_located((By.ID, 'email')))
    email_field.send_keys('testuser@example.com')

    # Wait for password field and enter password
    password_field = wait.until(EC.presence_of_element_located((By.ID, 'password')))
    password_field.send_keys('TestPass123')

    # Wait for login button to be clickable and click
    login_button = wait.until(EC.element_to_be_clickable((By.ID, 'loginBtn')))
    login_button.click()

    # Wait until URL contains '/dashboard'
    wait.until(EC.url_contains('/dashboard'))

    # Assertion: Verify URL contains '/dashboard'
    assert '/dashboard' in driver.current_url, 'Login failed or dashboard not loaded'

finally:
    driver.quit()

This script uses Selenium WebDriver with Python to run a test on BrowserStack cloud platform.

First, it sets up the remote WebDriver with BrowserStack credentials and desired capabilities for Windows 10 and Chrome latest.

It opens the login page URL, waits explicitly for the email and password fields to be present, then inputs the test credentials.

It waits for the login button to be clickable before clicking it.

After clicking, it waits until the URL contains '/dashboard' to confirm successful login.

Finally, it asserts that the URL contains '/dashboard' to verify the test passed.

The driver is quit in a finally block to ensure the browser session closes even if errors occur.

Common Mistakes - 4 Pitfalls

Using time.sleep() instead of explicit waits

{'mistake': 'Hardcoding local WebDriver instead of using remote WebDriver for BrowserStack', 'why_bad': "Tests won't run on BrowserStack cloud without remote WebDriver setup.", 'correct_approach': 'Use webdriver.Remote with BrowserStack hub URL and desired capabilities.'}

Not verifying elements are present or clickable before interacting

Not closing the browser session after test

Bonus Challenge

Now add data-driven testing with 3 different sets of login credentials to verify login success or failure.
