Select class for dropdowns in Selenium Python - Test Execution Trace

Test Overview

This test opens a webpage with a dropdown menu, selects an option by visible text using Selenium's Select class, and verifies the correct option is selected.

Test Code - unittest

Selenium Python

from selenium import webdriver
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.by import By
import unittest

class TestDropdownSelection(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.get('https://example.com/dropdown')

    def test_select_option_by_visible_text(self):
        driver = self.driver
        dropdown_element = driver.find_element(By.ID, 'dropdown')
        select = Select(dropdown_element)
        select.select_by_visible_text('Option 2')
        selected_option = select.first_selected_option
        self.assertEqual(selected_option.text, 'Option 2')

    def tearDown(self):
        self.driver.quit()

if __name__ == '__main__':
    unittest.main()

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts and Chrome browser opens	Browser window is open, ready to navigate	-	PASS
2	Browser navigates to 'https://example.com/dropdown'	Page with dropdown menu loaded	-	PASS
3	Find dropdown element by ID 'dropdown'	Dropdown element located on the page	-	PASS
4	Create Select object for dropdown element	Select object ready to interact with dropdown	-	PASS
5	Select option with visible text 'Option 2'	Dropdown option 'Option 2' is selected	Verify selected option text is 'Option 2'	PASS
6	Test ends and browser closes	Browser window closed	-	PASS

Failure Scenario

Failing Condition: Dropdown element with ID 'dropdown' is not found on the page

Execution Trace Quiz - 3 Questions

Which Selenium method is used to find the dropdown element?

A find_element(By.ID, 'dropdown')

B find_element(By.CLASS_NAME, 'dropdown')

C find_element(By.NAME, 'dropdown')

D find_element(By.TAG_NAME, 'select')

Key Result

Use Selenium's Select class to interact with dropdown menus by selecting options with visible text, which is more readable and less error-prone than selecting by index or value.
