Acceptance criteria verification in Testing Fundamentals - Test Execution Trace

Test Overview

This test checks if the login page meets the acceptance criteria by verifying the presence of username and password fields, and the login button. It then verifies that a successful login message appears after submitting valid credentials.

Test Code - Selenium

Execution Trace - 8 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser opened at https://example.com/login showing login page	-	PASS
2	Waits for username field to be present and visible	Username input field is visible on the page	Assert username field is displayed	PASS
3	Waits for password field to be present and visible	Password input field is visible on the page	Assert password field is displayed	PASS
4	Waits for login button to be present and visible	Login button is visible on the page	Assert login button is displayed	PASS
5	Enters 'validUser' into username field	Username field contains 'validUser'	-	PASS
6	Enters 'validPass123' into password field	Password field contains 'validPass123'	-	PASS
7	Clicks the login button	Login form submitted, page processing login	-	PASS
8	Waits for success message to appear	Success message 'Login successful' is visible on the page	Assert success message text equals 'Login successful'	PASS

Failure Scenario

Failing Condition: If any of the required elements (username, password, login button) are missing or the success message text is incorrect

Execution Trace Quiz - 3 Questions

What does the test verify first on the login page?

A Password strength

B Successful login message

C Presence of username field

D Page title

Key Result

Always verify all acceptance criteria elements are present and functional before asserting final success conditions to ensure comprehensive test coverage.
