Here, we have a test case with a setUp() method that is run once at the start of the test suite and a tearDown() method that is run at the end.

Here is a subset of the contents linked to the test setup and teardown at the top of serverless-microservice-data-api/test/test_dynamo_get.py:

import unittest
import json

class TestIndexGetMethod(unittest.TestCase):
    def setUp(self):
        self.validJsonDataNoStartDate = json.loads('{"httpMethod": 
        "GET","path": "/path/to/resource/324","headers": '  'null} ')
        self.validJsonDataStartDate = 
        json.loads('{"queryStringParameters": {"startDate":      
        "20171013"},'  '"httpMethod": "GET","path": "/path/to/resource
        /324","headers": '  'null} ')
        self.invalidJsonUserIdData =   
        json.loads('{"queryStringParameters": {"startDate": 
        "20171013"},'  '"httpMethod": "GET","path": "/path/to/resource
        /324f","headers": '  'null} ')
        self.invalidJsonData = "{ invalid JSON request!} "
    def tearDown(self):
        pass

I created four different JSON Python dictionaries:

• self.validJsonDataNoStartDate: A valid GET request with no StartDate filter
• self.validJsonDataStartDate: A valid GET request with a StartDate filter
• self.invalidJsonUserIdData: An invalid UserId that is not a number
• self.invalidJsonData: Invalid JSON that cannot be parsed
