input: Write a python function to generate three random integers between 1 and 10.
  assert isinstance(generate_random_integers(), tuple) and len(generate_random_integers()) == 3
  assert all(1 <= n <= 10 for n in generate_random_integers())
output: import random
  
  def generate_random_integers():
      return (random.randint(1, 10), random.randint(1, 10), random.randint(1, 10))
