Writing a first round of unit tests

Now, we will write a first round of unit tests. Specifically, we will write unit tests related to the LED resources. Create a new tests subfolder within the virtual environment's root folder. Then, create a new test_hexacopter.py file within the new tests subfolder. Add the following lines that declare many import statements and the TextHexacopter class. The code file for the sample is included in the restful_python_chapter_10_02 folder:

import unittest 
import status 
import json 
from tornado import ioloop, escape 
from tornado.testing import AsyncHTTPTestCase, gen_test, gen 
from async_api import Application 
 
 
class TestHexacopter(AsyncHTTPTestCase): 
    def get_app(self): 
        self.app = Application(debug=False) 
        return self.app 
 
    def test_set_and_get_led_brightness_level(self): 
        """ 
        Ensure we can set and get the brightness levels for both LEDs 
        """ 
        patch_args_led_1 = {'brightness_level': 128} ...
