Find element by tag name in Selenium Python - Test Execution Trace

Test Overview

This test opens a web page and finds the first <h1> tag element. It verifies that the text inside the <h1> tag matches the expected heading.

Test Code - Selenium

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
import unittest

class TestFindElementByTagName(unittest.TestCase):
    def setUp(self):
        options = Options()
        options.add_argument('--headless')
        service = Service()
        self.driver = webdriver.Chrome(service=service, options=options)

    def test_find_h1_by_tag_name(self):
        self.driver.get('https://example.com')
        element = self.driver.find_element(By.TAG_NAME, 'h1')
        self.assertEqual(element.text, 'Example Domain')

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

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

Execution Trace - 6 Steps

Step	Action	System State	Assertion	Result
1	Test starts	Test framework initializes and prepares the test environment	-	PASS
2	Browser opens in headless mode	Chrome browser instance is launched without UI	-	PASS
3	Navigates to 'https://example.com'	Browser loads the Example Domain page with a visible <h1> element	-	PASS
4	Finds element by tag name 'h1' using driver.find_element(By.TAG_NAME, 'h1')	The first <h1> element on the page is located	-	PASS
5	Checks that the text of the <h1> element equals 'Example Domain'	The element text is 'Example Domain'	assertEqual(element.text, 'Example Domain')	PASS
6	Browser closes and test ends	Browser instance is terminated cleanly	-	PASS

Failure Scenario

Failing Condition: The <h1> tag is missing or the text inside it does not match 'Example Domain'

Execution Trace Quiz - 3 Questions

What Selenium method is used to find the <h1> element in this test?

A driver.find_element(By.TAG_NAME, 'h1')

B driver.find_element(By.ID, 'h1')

C driver.find_element(By.CLASS_NAME, 'h1')

D driver.find_element(By.CSS_SELECTOR, 'h1')

Key Result

Use find_element with By.TAG_NAME to locate elements by their tag. Always verify the element's text to ensure you found the correct element.
