Selenium WebDriver scenarios to execute assertions on partially loaded content in Django application with Chrome 120
Hey everyone, I'm running into an issue that's driving me crazy. This might be a silly question, but I'm stuck on something that should probably be simple. I'm working with an scenario where Selenium WebDriver is unable to properly assert the presence of elements that are dynamically loaded in my Django application. The elements load progressively, and sometimes my assertions unexpected result because the elements aren’t fully rendered yet. For instance, I’m trying to assert that a specific item appears on the page after a button click, but the assertion often fails because the item takes longer to load than Selenium waits by default. Here’s a snippet where I try to click a button and wait for an element: ```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 # Initialize the Chrome WebDriver driver = webdriver.Chrome() driver.get('http://localhost:8000/my-django-page') # Click the button that triggers the loading of the new content button = driver.find_element(By.ID, 'load-more-button') button.click() # Wait for the new element that should appear try: element = WebDriverWait(driver, 10).until( EC.presence_of_element_located((By.CLASS_NAME, 'new-item')) ) assert element.is_displayed() # This often fails except Exception as e: print(f'behavior: {str(e)}') finally: driver.quit() ``` I’ve tried increasing the wait time, but it still doesn’t consistently work. Sometimes, I get a timeout exception, and other times, the element is found but isn’t fully rendered, leading to assertion failure. I’ve also considered using `EC.visibility_of_element_located` instead of `EC.presence_of_element_located`, but it doesn't seem to improve the situation. Is there a better strategy for handling elements that load dynamically in a Django application? Should I be using a different waiting mechanism or a different approach altogether? Any insights would be greatly appreciated! I'm working on a CLI tool that needs to handle this. What am I doing wrong? I'm working on a web app that needs to handle this. The project is a application built with Python. I'd love to hear your thoughts on this. My team is using Python for this CLI tool. What's the correct way to implement this? My development environment is Ubuntu 20.04. Any help would be greatly appreciated!
