Select by value, text, index in Selenium Python - Test Execution Trace

Test Overview

This test opens a webpage with a dropdown menu and selects options using three methods: by value, by visible text, and by index. It verifies that the correct option is selected each time.

Test Code - unittest

Execution Trace - 8 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser is open with blank page	-	PASS
2	Navigates to 'https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_select'	Page loads with iframe containing dropdown	-	PASS
3	Switches to iframe 'iframeResult'	Inside iframe, dropdown with id 'cars' is visible	-	PASS
4	Finds dropdown element by ID 'cars'	Dropdown element located	-	PASS
5	Selects option by value 'volvo'	Dropdown option 'Volvo' is selected	Check selected option's value is 'volvo'	PASS
6	Selects option by visible text 'Saab'	Dropdown option 'Saab' is selected	Check selected option's text is 'Saab'	PASS
7	Selects option by index 3	Dropdown option 'Audi' is selected	Check selected option's text is 'Audi'	PASS
8	Test ends and browser closes	Browser closed	-	PASS

Failure Scenario

Failing Condition: Dropdown element with ID 'cars' is not found or option value/text/index does not exist

Execution Trace Quiz - 3 Questions

Which method is used to select the option with value 'volvo'?

A select.select_by_value('volvo')

B select.select_by_visible_text('volvo')

C select.select_by_index('volvo')

D select.select('volvo')

Key Result

Always switch to the correct iframe before interacting with elements inside it, and verify selections by checking the selected option's value or text to ensure the correct item is chosen.
