Healthcheck-bot

A simple Python script to verify if a service is up. Whenever the service falls, a message will be sent to a user/group/channel with Telegram

How to use?

Just set two env variables:

• QDBotToken, your bot token
• QDBotIDs, the ID(s) the bot will use to communicate any downtime. It's possible to set multiple IDs, semicolon separated without any space

Example in bash

export QDBotToken="123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11" # Your bot token
export QDBotIDs="10000000"                                      # Single ID
export QDBotIDs="10000000;10000001;10000002"                    # Multiple IDs

Write Unit Tests

In order to write Unit Tests, you have to put it inside tests. There are many possibilities,

Unit Tests without mocking

To add a new unit test without mocking, there are some examples at the beginning of tests, but let's inspect how they're implemented:

• func: simply the function to mock
• expected_res: the expected returned value of the function to test
• arg: a tuple that contains the argument(s) of the function to test (the one previously defined in func). In case there are no passing arguments, just add an empty tuple object (tuple())
• is_async: this is not a compulsory key, should be added and set to True only if the function is asynchronous

Unit Tests with mocking

If is necessary one or more mock(s), it's possible to append three more keys to the unit test. In case an async function needs to be mocked, its result can be wrapped in an AsyncMock and its return value set as a constructor element in the constructor. The test should have the same keys with three more keys:

• mock_obj: it's a list of the objects in which there are the functions to mock. In our examples they often refer to the main object (the one imported from src.main)
• mock_func: an array of strings, it indicates the functions to mock
• mock_ret: a list of the returned values
