Risk-based testing in Testing Fundamentals - Test Execution Trace

Test Overview

This test checks that the highest risk features of a web application load correctly and display expected content. It verifies that the critical parts of the app work as expected to reduce the chance of major failures.

Test Code - Selenium

import unittest
from selenium import webdriver
from selenium.webdriver.common.by import By

        wait = WebDriverWait(driver, 10)
        # Wait for critical feature element to be present
        critical_element = wait.until(EC.presence_of_element_located((By.ID, 'critical-feature')))
        # Check the text content is as expected
        self.assertEqual(critical_element.text, 'Critical Feature Active')

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser window is open and ready	-	PASS
2	Browser navigates to 'https://example.com'	Page is loading	-	PASS
3	Waits up to 10 seconds for element with ID 'critical-feature' to be present	Page loaded with element 'critical-feature' visible	Element with ID 'critical-feature' is present	PASS
4	Checks that the text of 'critical-feature' element equals 'Critical Feature Active'	Element text is 'Critical Feature Active'	Element text matches expected string	PASS
5	Browser closes and test ends	Browser closed	-	PASS

Failure Scenario

Failing Condition: The element with ID 'critical-feature' is missing or text is incorrect

Execution Trace Quiz - 3 Questions

What does the test wait for before checking the element's text?

A The page title to be 'Home'

B The presence of the element with ID 'critical-feature'

C The browser to be maximized

D The URL to change

Key Result

Focus testing efforts on the most important and risky features first to catch critical issues early and use explicit waits to handle dynamic page loading.
