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?

https://slack.dev/bolt-python/ の Bolt for Python ドキュメントから始め、main.py と api.py に示されているハンドラー構造を確認します。これには app.command、app.event、app.db、ack、respond が含まれます。これらのハンドラーの単体テストについて、ハンドラーの引数と app の依存関係に対するテストダブルを含む、妥当なアプローチを、期待される動作が明確になる例とともに文書化します。
