Verify login button becomes clickable after page load

Preconditions (2)

Step 1: Open the login page URL in browser

Step 2: Wait for the login button to become clickable

Step 3: Click the login button

Step 4: Verify that the next page URL contains '/dashboard'

✅ Expected Result: Login button is clicked only after it is clickable, and user is navigated to dashboard page

Automation Requirements - Selenium with Python

Assertions Needed:

Assert login button is clickable before clicking

Assert current URL contains '/dashboard' after click

Best Practices:

Use explicit waits (WebDriverWait) for synchronization

Avoid hardcoded sleeps

Use By locators for element identification

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

# Setup WebDriver
with webdriver.Chrome() as driver:
    driver.get('https://example.com/login')

    wait = WebDriverWait(driver, 10)  # Wait up to 10 seconds

    # Wait until login button is clickable
    login_button = wait.until(EC.element_to_be_clickable((By.ID, 'login-btn')))

    # Click the login button
    login_button.click()

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

    # Assert current URL contains '/dashboard'
    assert '/dashboard' in driver.current_url, f"Expected '/dashboard' in URL but got {driver.current_url}"

This script uses Selenium WebDriver with Python to automate the test case.

First, it opens the login page URL.

Then, it uses WebDriverWait with element_to_be_clickable to wait explicitly until the login button is ready to be clicked. This prevents clicking too early, which can cause flaky tests.

After the button is clickable, it clicks the button.

Next, it waits until the URL contains '/dashboard' to confirm navigation.

Finally, it asserts the URL contains '/dashboard' to verify the expected result.

This approach avoids using fixed sleeps and relies on synchronization to make the test stable and reliable.

Common Mistakes - 3 Pitfalls

Using time.sleep() instead of explicit waits

Clicking elements immediately after page load without waiting

Using incorrect or brittle locators like absolute XPath

Bonus Challenge

Now add data-driven testing with 3 different login URLs to verify synchronization works on all.
