Prompt alert text entry in Selenium Java - Test Execution Trace

Test Overview

This test opens a web page with a prompt alert, enters text into the prompt, accepts it, and verifies the result message on the page.

Execution Trace - 7 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Chrome browser window is open and ready	-	PASS
2	Navigates to https://the-internet.herokuapp.com/javascript_alerts	Page with JavaScript alerts buttons is loaded	Page title or URL can be verified (implicit)	PASS
3	Finds button with text 'Click for JS Prompt' and clicks it	Prompt alert dialog appears on screen	Alert presence is detected by WebDriverWait	PASS
4	Switches to alert, enters text 'Selenium Test' into prompt	Prompt alert contains input text 'Selenium Test'	Alert is interactable and accepts text input	PASS
5	Accepts the prompt alert	Alert disappears, page updates result text	Alert is accepted successfully	PASS
6	Finds element with id 'result' and reads its text	Result text is visible on page	Result text equals 'You entered: Selenium Test'	PASS
7	Test ends and browser closes	Browser window is closed	-	PASS

Failure Scenario

Failing Condition: Prompt alert does not appear or text input fails

Execution Trace Quiz - 3 Questions

What Selenium method is used to enter text into the prompt alert?

A sendKeys() on WebElement

B sendKeys() on Alert object

C setText() on Alert object

D type() on WebElement

Key Result

Always use explicit waits like WebDriverWait to handle alerts reliably before interacting with them.
