Find element by XPath in Selenium Python - Test Execution Trace

Test Overview

This test opens a web page, finds a button using its XPath locator, clicks it, and verifies that a confirmation message appears.

Test Code - Selenium

Selenium Python

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import unittest

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

    def test_click_button_by_xpath(self):
        driver = self.driver
        wait = WebDriverWait(driver, 10)
        # Find the button using XPath
        button = wait.until(EC.element_to_be_clickable((By.XPATH, '//button[@id="submit-btn"]')))
        button.click()
        # Verify confirmation message appears
        confirmation = wait.until(EC.visibility_of_element_located((By.XPATH, '//div[@id="confirmation"]')))
        self.assertEqual(confirmation.text, 'Submission successful')

    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	Chrome browser window is open and ready	-	PASS
2	Browser navigates to 'https://example.com/testpage'	Page loads fully with button and confirmation elements present	-	PASS
3	Wait until button with XPath '//button[@id="submit-btn"]' is clickable and find it	Button element is found and ready to be clicked	-	PASS
4	Click the button found by XPath	Button is clicked, page reacts accordingly	-	PASS
5	Wait until confirmation message with XPath '//div[@id="confirmation"]' is visible	Confirmation message element is visible on the page	Check that confirmation text equals 'Submission successful'	PASS
6	Test ends and browser closes	Browser window is closed	-	PASS

Failure Scenario

Failing Condition: The button with the specified XPath is not found or not clickable within 10 seconds

Execution Trace Quiz - 3 Questions

Which Selenium method is used to find the button by XPath?

A driver.find_element(By.XPATH, '//button[@id="submit-btn"]')

B driver.find_element_by_id('submit-btn')

C driver.find_element(By.CSS_SELECTOR, '#submit-btn')

D driver.find_element_by_name('submit-btn')

Key Result

Use explicit waits with WebDriverWait and expected_conditions to reliably find elements by XPath before interacting with them.
