selenium react webdriver Python

I'm optimizing some code but I'm relatively new to this, so bear with me. This might be a silly question, but I'm working with an scenario with Selenium WebDriver where it need to locate elements in my React application after a state update. Specifically, I have a component that fetches data and updates the state upon a button click. After the state updates, the elements I need to interact with become invisible, and I receive a `NoSuchElementException`. Here's the relevant part of my code: ```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 driver chrome_options = webdriver.ChromeOptions() chrome_options.add_argument('--headless') # Running in headless mode for CI driver = webdriver.Chrome(options=chrome_options) try: driver.get('http://localhost:3000') # Click the button to fetch data fetch_button = driver.find_element(By.ID, 'fetchDataButton') fetch_button.click() # Wait for the state to update and the new elements to render WebDriverWait(driver, 10).until( EC.presence_of_element_located((By.CLASS_NAME, 'data-item')) ) # Attempt to interact with the new elements data_items = driver.find_elements(By.CLASS_NAME, 'data-item') for item in data_items: print(item.text) finally: driver.quit() ``` I've tried increasing the wait time and using different strategies for locating elements, but nothing seems to work. The question occurs intermittently, mainly when the AJAX call takes longer than expected. My application is built using React 17 and I'm testing with Chrome 120. Any insights on how to handle this type of situation or if there's a best practice for waiting for state updates in React components would be appreciated! I'm working on a CLI tool that needs to handle this. How would you solve this? This is happening in both development and production on Windows 11. The stack includes Python and several other technologies. What are your experiences with this?
