Action methods in page class in Selenium Python - Test Execution Trace

Test Overview

This test opens a web page, uses an action method from a page class to click a button, and verifies the button click changes the page text as expected.

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 SamplePage:
    def __init__(self, driver):
        self.driver = driver
        self.button_locator = (By.ID, "click-me")
        self.message_locator = (By.ID, "message")

    def click_button(self):
        button = WebDriverWait(self.driver, 10).until(
            EC.element_to_be_clickable(self.button_locator)
        )
        button.click()

    def get_message_text(self):
        message = WebDriverWait(self.driver, 10).until(
            EC.visibility_of_element_located(self.message_locator)
        )
        return message.text

class TestActionMethods(unittest.TestCase):
    def setUp(self):
        self.driver = webdriver.Chrome()
        self.driver.get("https://example.com/samplepage")
        self.page = SamplePage(self.driver)

    def test_click_button_changes_message(self):
        self.page.click_button()
        text = self.page.get_message_text()
        self.assertEqual(text, "Button clicked!")

    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 and ready	-	PASS
2	Navigates to https://example.com/samplepage	Sample page loads with a button labeled 'Click me' and a hidden message area	-	PASS
3	Calls page.click_button() which waits for button to be clickable and clicks it	Button is clicked, triggering message display	-	PASS
4	Calls page.get_message_text() which waits for message to be visible and retrieves text	Message area shows text 'Button clicked!'	Verify message text equals 'Button clicked!'	PASS
5	Test assertion checks if retrieved text matches expected	Text matches expected	assertEqual(text, 'Button clicked!')	PASS
6	Browser closes and test ends	Browser window closed	-	PASS

Failure Scenario

Failing Condition: Button with ID 'click-me' is not found or not clickable within 10 seconds

Execution Trace Quiz - 3 Questions

What does the method click_button() do in the page class?

A Opens the browser and navigates to the page

B Retrieves the text from the message area

C Waits for the button to be clickable and clicks it

D Closes the browser after the test

Key Result

Using action methods in a page class helps keep test code clean and reusable by separating page interactions from test logic.
