Exploratory testing in Testing Fundamentals - Test Execution Trace

Test Overview

This test explores a simple login page without a fixed script. It tries different inputs and checks if the login button behaves correctly, verifying the system handles inputs as expected.

Test Code - Selenium with unittest

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and opens Chrome browser	Browser opened at https://example.com/login showing login form with username, password fields and disabled login button	-	PASS
2	Waits for username field to be present and finds password and login button elements	All elements are visible and interactable	-	PASS
3	Checks that login button is initially disabled	Login button is disabled	Assert login_button.is_enabled() is False	PASS
4	Enters 'testuser' in username field	Username field contains 'testuser', password empty, login button still disabled	Assert login_button.is_enabled() is False	PASS
5	Enters 'password123' in password field	Username and password fields filled, login button enabled	Assert login_button.is_enabled() is True	PASS
6	Clears username field	Username empty, password filled, login button disabled	Assert login_button.is_enabled() is False	PASS
7	Test ends and browser closes	Browser closed	-	PASS

Failure Scenario

Failing Condition: Login button remains enabled even when username or password fields are empty

Execution Trace Quiz - 3 Questions

What does the test check after entering only the username?

A Login button remains disabled

B Login button becomes enabled

C Password field is cleared

D Page reloads

Key Result

Exploratory testing involves trying different inputs and observing system behavior without a fixed script, helping find unexpected issues.
