  function signature:
  from selenium import webdriver
  def scrape_products(url, keyword):
      driver = webdriver.Firefox()
      driver.implicitly_wait(30)
      driver.maximize_window()
      driver.get(url)
      search_field = driver.find_element_by_name("q")
      search_field.clear()
      search_field.send_keys(keyword)
      search_field.submit()
      product_list = driver.find_elements_by_class_name("product")
      for product in product_list:
          print(product.text)
      driver.quit()
  
  assert scrape_products("https://www.example.com/", "shoes")==None
  assert scrape_products("https://www.example.com/", "shirts")==None

      driver = webdriver.Firefox()
      driver.implicitly_wait(30)
      driver.maximize_window()
      driver.get(url)
