By default, any command will read any incoming message. `Context` can be used to easily reply (`c.send(text)`), react (`c.react(emoji)`) and to type in a group (`c.start_typing()` and `c.stop_typing()`). You can use the `@triggered` decorator to listen for specific commands or you can inspect `c.message.text`.

 ### Unit Testing

 In many cases, we can mock receiving and sending messages to speed up development time. To do so, you can use `signalbot.utils.ChatTestCase` which sets up a "skeleton" bot. Then, you can send messages using the `@chat` decorator in `signalbot.utils` like this:
 ```python
 class PingChatTest(ChatTestCase):
