Test Code - Selenium

from selenium import webdriver

    def setUp(self):

        # Wait for alert to be present
        WebDriverWait(driver, 10).until(EC.alert_is_present())

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts and opens Chrome browser	Browser window opens at 'https://the-internet.herokuapp.com/javascript_alerts'	-	PASS
2	Finds the button with text 'Click for JS Prompt' and clicks it	Prompt alert dialog appears on screen	-	PASS
3	Waits up to 10 seconds for alert to be present	Alert is present and active	-	PASS
4	Switches to alert, sends text 'Hello Test', and accepts the alert	Alert closes, page shows updated result text	-	PASS
5	Finds element with id 'result' and verifies its text equals 'You entered: Hello Test'	Page displays confirmation message with entered text	Assert that result text is exactly 'You entered: Hello Test'	PASS
6	Test ends and browser closes	Browser window closes	-	PASS

Failure Scenario

Failing Condition: Alert does not appear or text in result does not match expected

Execution Trace Quiz - 3 Questions

What action triggers the prompt alert in this test?

A Navigating to the page URL

B Clicking the button labeled 'Click for JS Prompt'

C Sending keys to the alert

D Waiting for the alert to appear

Key Result

Always wait explicitly for alerts before interacting with them to avoid timing issues, and verify the page updates after alert actions.
