Selenium components (WebDriver, Grid, IDE) in Selenium Python - Test Execution Trace

Test Overview

This test opens a browser using Selenium WebDriver, navigates to a sample website, finds a button, clicks it, and verifies the page title changes as expected. It demonstrates WebDriver usage. Grid and IDE are explained in the insight.

Test Code - Selenium

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 TestButtonClick(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.implicitly_wait(5)

    def test_click_button_changes_title(self):
        self.driver.get('https://example.com')
        button = WebDriverWait(self.driver, 10).until(
            EC.element_to_be_clickable((By.ID, 'start-button'))
        )
        button.click()
        WebDriverWait(self.driver, 10).until(
            EC.title_is('Example Domain - Started')
        )
        self.assertEqual(self.driver.title, 'Example Domain - Started')

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

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

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome WebDriver is launched	Chrome browser window opens, ready to navigate	-	PASS
2	Browser navigates to 'https://example.com'	Page loads with title 'Example Domain'	-	PASS
3	Waits until button with ID 'start-button' is clickable	Button is visible and enabled on the page	Button is found and clickable	PASS
4	Clicks the 'start-button'	Page reacts to click, title expected to change	-	PASS
5	Waits until page title changes to 'Example Domain - Started'	Page title updates accordingly	Title is exactly 'Example Domain - Started'	PASS
6	Asserts that the page title is 'Example Domain - Started'	Title matches expected value	assertEqual passes	PASS
7	Test ends and browser closes	Browser window closes cleanly	-	PASS

Failure Scenario

Failing Condition: Button with ID 'start-button' is not found or not clickable within 10 seconds

Execution Trace Quiz - 3 Questions

What does the test verify after clicking the button?

A The URL changes to a new domain

B The button disappears from the page

C The page title changes to 'Example Domain - Started'

D An alert popup appears

Key Result

Using Selenium WebDriver allows automated control of real browsers for testing. Selenium Grid enables running tests on multiple machines or browsers in parallel. Selenium IDE is a tool for recording and playing back tests without coding.
