Test environment setup in Testing Fundamentals - Test Execution Trace

Test Overview

This test checks if the test environment is correctly set up before running any tests. It verifies that the browser opens, the test URL loads, and the main page elements are present.

Test Code - Selenium with unittest

Testing Fundamentals

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

    def test_environment_ready(self):
        driver = self.driver
        driver.get('https://example.com')
        WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.TAG_NAME, 'h1')))
        heading = driver.find_element(By.TAG_NAME, 'h1')
        self.assertTrue(heading.is_displayed())

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

    unittest.main()

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and WebDriver Chrome instance is created	Browser window opens, ready for commands	-	PASS
2	Browser navigates to 'https://example.com'	Browser loads the example.com homepage	-	PASS
3	Waits up to 10 seconds for the <h1> element to be present	<h1> element appears on the page	Checks presence of <h1> element	PASS
4	Finds the <h1> element and checks if it is displayed	<h1> element is visible on the page	Assert that heading.is_displayed() is True	PASS
5	Test ends and browser closes	Browser window closes	-	PASS

Failure Scenario

Failing Condition: The <h1> element does not appear within 10 seconds after loading the page

Execution Trace Quiz - 3 Questions

What does the test verify after opening the browser and loading the page?

A That the browser window is maximized

B That the main heading <h1> is present and visible

C That the page title contains 'Welcome'

D That the URL contains 'login'

Key Result

Always verify that the test environment is correctly set up by checking key page elements before running further tests. This prevents false failures caused by environment issues.
