Selenium WebDriver fails to validate ARIA attributes in a staging environment for WCAG compliance testing
After trying multiple solutions online, I still can't figure this out... This might be a silly question, but Currently developing an accessibility-focused application and running into a roadblock with Selenium WebDriver while attempting to validate ARIA attributes for WCAG compliance in our staging environment. The goal is to ensure that all interactive elements adhere to accessibility standards. For instance, I'm trying to check if a button has the appropriate ARIA label. Here’s the snippet I’m using: ```python from selenium import webdriver from selenium.webdriver.common.by import By driver = webdriver.Chrome() driver.get('https://staging.example.com') # Attempting to locate a button with ARIA label button = driver.find_element(By.XPATH, "//button[@aria-label='Submit']") assert button is not None, 'Button not found!' ``` This code runs without an exception, but when I inspect the button in the browser, the ARIA label seems to be missing, and I can't figure out if this is a timing issue or if the element is not being rendered correctly at the moment of the check. I’ve tried employing WebDriverWait to ensure the button is loaded: ```python from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC button = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, "//button[@aria-label='Submit']"))) ``` This approach did not yield different results. Additionally, I’ve explored the possibility of conflicting JavaScript that might be altering the ARIA attributes after the button is identified. To debug further, I included a script to print the ARIA attributes directly: ```python aria_label = driver.execute_script("return arguments[0].getAttribute('aria-label');", button) print(f'ARIA Label: {aria_label}') ``` This revealed that the ARIA label is indeed absent, which is perplexing. The staging environment is built with React and uses React Accessibility APIs. Is there a known issue with Selenium interacting with dynamically rendered components, particularly concerning ARIA attributes? Any insights into approaching this problem or alternative strategies for testing accessibility would be greatly appreciated. I'm working on a API that needs to handle this. Am I missing something obvious? For context: I'm using Python on macOS. What am I doing wrong?
