Transitioning to automation in Testing Fundamentals - Test Execution Trace

Test Overview

This test simulates a simple web login automation to verify that the login button works and the user is redirected to the dashboard page. It checks if automation can successfully perform a login action and validate the result.

Test Code - Selenium with unittest

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
import unittest

class TestLoginAutomation(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.get('https://example.com/login')

    def test_login_button_redirects(self):
        driver = self.driver
        # Wait until login button is clickable
        login_button = WebDriverWait(driver, 10).until(
            EC.element_to_be_clickable((By.ID, 'login-btn'))
        )
        login_button.click()
        # Wait until dashboard page loads by checking URL
        WebDriverWait(driver, 10).until(
            EC.url_contains('/dashboard')
        )
        self.assertIn('/dashboard', driver.current_url)

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser window opened at https://example.com/login	-	PASS
2	Wait until login button with ID 'login-btn' is clickable	Login page fully loaded with login button visible and enabled	Login button is clickable	PASS
3	Click the login button	Browser navigates to new page after click	-	PASS
4	Wait until URL contains '/dashboard' indicating page load	Dashboard page loaded with URL containing '/dashboard'	Current URL contains '/dashboard'	PASS
5	Assert that current URL contains '/dashboard'	Dashboard page visible	assertIn('/dashboard', driver.current_url)	PASS
6	Close browser and end test	Browser closed	-	PASS

Failure Scenario

Failing Condition: Login button with ID 'login-btn' is not found or not clickable within 10 seconds

Execution Trace Quiz - 3 Questions

What does the test check after clicking the login button?

A If the page title changes to 'Login Page'

B If the URL contains '/dashboard' indicating successful navigation

C If the login button changes color

D If an alert popup appears

Key Result

Always wait explicitly for elements to be ready before interacting in automation to avoid flaky tests caused by timing issues.
