Document about the ways to write unit tests for Bolt apps

I am looking to write unit tests for my Bolt API, which consists of an app with several handlers for events / messages. The handlers are both decorated using the app.event decorator, and make use of the app object to access things like the db connection that has been put on it. For example:

# in main.py
app = App(
    token=APP_TOKEN,
    signing_secret=SIGNING_SECRET,
    process_before_response=True,
    token_verification_enabled=token_verification_enabled,
)
app.db = db

# in api.py:
from .main import app

@app.command("/slashcommand")
def slash_command(ack, respond):
    ack()
    results = app.db.do_query()
    respond(...)

The thing is, I cannot find any framework pointers, or documentation, on how I would write reasonable unit tests for this. Presumably ones where the kwargs like ack and respond are replaced by test doubles. How do I do this?

Commencez par la documentation de Bolt for Python à l’adresse https://slack.dev/bolt-python/ et examinez la structure des handlers présentée dans main.py et api.py, notamment app.command, app.event, app.db, ack et respond. Documentez une approche raisonnable des tests unitaires de ces handlers, notamment des test doubles pour les arguments des handlers et les dépendances de app, avec des exemples qui rendent le comportement attendu clair.
