Fluent waits in Selenium Python - Test Execution Trace

Test Overview

This test uses a fluent wait to wait for a button to become clickable on a webpage. It verifies that the button can be clicked successfully.

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
from selenium.common.exceptions import TimeoutException

# Setup WebDriver
driver = webdriver.Chrome()
driver.get('https://example.com')

try:
    wait = WebDriverWait(driver, 10, poll_frequency=0.5, ignored_exceptions=[Exception])
    button = wait.until(EC.element_to_be_clickable((By.ID, 'submit-btn')))
    button.click()
    assert driver.current_url != 'https://example.com', 'URL did not change after click'
finally:
    driver.quit()

Execution Trace - 5 Steps

Step	Action	System State	Assertion	Result
1	Test starts and WebDriver Chrome instance is created	Browser window opens at 'https://example.com'	-	PASS
2	WebDriverWait with fluent wait settings is created (10s timeout, 0.5s polling, ignoring TimeoutException)	Waiting for element with ID 'submit-btn' to be clickable	-	PASS
3	Wait polls every 0.5 seconds until the button with ID 'submit-btn' is clickable	Button becomes clickable within timeout	Element is clickable	PASS
4	Button is clicked	Browser navigates or updates after click	Current URL is different from initial URL 'https://example.com'	PASS
5	WebDriver quits and browser closes	Browser window closed	-	PASS

Failure Scenario

Failing Condition: Button with ID 'submit-btn' does not become clickable within 10 seconds

Execution Trace Quiz - 3 Questions

What does the fluent wait do in this test?

A It clicks the button immediately without waiting

B It waits up to 10 seconds, checking every 0.5 seconds if the button is clickable

C It waits only once for 10 seconds before clicking

D It waits for the page to load completely without checking the button

Key Result

Use fluent waits to repeatedly check for an element's condition with polling and ignored exceptions, making tests more reliable for dynamic web pages.
