{
  test_result: // JSON.stringify({
    {api_name}: {
      "preparation": (-1/0/1), # -1: no preparation needed
                               #  0: not prepared (and it should)
                               #  1: prepared
      "tests": {
		{testName}: (0/1),   #  0: failed
							 #  1: passed
		...
	  },
	  ("timeout": 1)           #  any test interrupted by setTimeout
    },
    ...
  }),
  device: // currently null, we might have some way to provide the model,
