Enhanced Dependency Management

Zetten provides robust hooks for managing task lifecycles, ensuring your environment is always in a known state.

Setup & Teardown

You can define setup and teardown tasks for any task.

[tasks.db_test]
cmd = "pytest tests/db"
setup = "db_init"
teardown = "db_clean"

Behavior

1. Setup (db_init): Runs before db_test. If setup fails, db_test is skipped.
2. Main Task (db_test): Runs only if setup succeeds.
3. Teardown (db_clean): Runs after db_test completes, regardless of success or failure.

This is crucial for cleanup tasks like dropping test databases or removing temporary files.

DAG Dependencies

Standard dependencies still apply via depends_on:

[tasks.test]
depends_on = ["lint", "build"]

Zetten guarantees lint and build finish successfully before test starts.
