Jenkins integration in Selenium Python - Test Execution Trace

Test Overview

This test automates a simple login scenario using Selenium WebDriver in Python. It verifies that the login button is clickable and that the user is redirected to the dashboard page after login. This test is designed to be integrated and run in Jenkins for continuous testing.

Test Code - Selenium with unittest

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
import unittest

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

    def test_login(self):
        driver = self.driver
        # Wait until the username field is present
        WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, 'username')))
        username_input = driver.find_element(By.ID, 'username')
        password_input = driver.find_element(By.ID, 'password')
        login_button = driver.find_element(By.ID, 'login-btn')

        username_input.send_keys('testuser')
        password_input.send_keys('password123')
        login_button.click()

        # Wait until redirected to dashboard
        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 - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts - unittest framework initializes the test case	Test runner is ready to execute the test	-	PASS
2	Browser opens Chrome and navigates to 'https://example.com/login'	Login page is loaded in the browser	WebDriverWait waits for username field presence	PASS
3	Find username, password input fields and login button by ID	All elements are located on the login page	Elements are found without exceptions	PASS
4	Enter 'testuser' in username and 'password123' in password fields	Input fields contain the entered text	-	PASS
5	Click the login button	Browser submits login form	-	PASS
6	Wait until URL contains '/dashboard' indicating successful login	Browser navigates to dashboard page	Assert current URL contains '/dashboard'	PASS
7	Test ends - browser closes	Browser window is closed	-	PASS

Failure Scenario

Failing Condition: Login button element with ID 'login-btn' is not found on the page

Execution Trace Quiz - 3 Questions

What does the test verify after clicking the login button?

A That the URL contains '/dashboard' indicating successful login

B That the login button becomes disabled

C That an error message appears on the login page

D That the username field is cleared

Key Result

Always use explicit waits like WebDriverWait to ensure elements are present before interacting, especially in automated tests run in CI tools like Jenkins.
