Tecton Repo Fixture

The Tecton Repo Fixture is a pytest fixture that provides methods to access Tecton Objects defined in your feature repository that you might want to use in your unit tests.

You can access the Repo Fixture by simply adding the repo_fixture parameter to your unit tests in the following manner:

from tecton import TestRepo


def test_tecton_objects(repo_fixture: TestRepo):
    # Test code goes here
    pass

The repo_fixture is an object of type TestRepo. Please refer to the SDK Reference to view all the available methods and properties for the TestRepo class.

This can be valuable to assert properties that have been set on your Tecton Objects and maintain consistency across all objects managed by your team.

from tecton import TestRepo, DeltaConfig


def test_tecton_objects(repo_fixture: TestRepo):

    # Online and Offline Materialization is enabled on all FVs
    for feature_view in repo_fixture.feature_views:
        assert fv.online
        assert fv.offline

    # Feature view is using Delta as the Offline Store
    fv = repo_fixture.get_feature_view("user_transactions_fv")
    assert fv.offline_store == DeltaConfig

    for tecton_object in repo_fixture.get_all_objects():
        # Team's owner tags are set on all objects
        object_tags = tecton_object.tags
        assert object_tags["owner"] == "Feature Engineering"

        # All objects should have descriptions
        assert len(object_tags.description) > 0
