Test Harness

This repository includes the OpenFeature provider verifier as a git submodule. After cloning, initialize it before running the full test suite:

git submodule update --init --recursive

If the verifier submodule is intentionally updated, refresh it and commit the new submodule pointer:

git submodule update --remote --merge verifier
git status

Use

from openfeature import api
from openfeature.evaluation_context import EvaluationContext
from UnleashClient import UnleashClient

from unleash_openfeature_python_provider import UnleashFlagProvider

unleash_client = UnleashClient(
    url="https://app.unleash-hosted.com/demo/api",
    app_name="my-app",
    custom_headers={"Authorization": "<client-api-key>"},
)

api.set_provider_and_wait(UnleashFlagProvider(unleash_client))

client = api.get_client()
enabled = client.get_boolean_value(
    "my-feature",
    False,
    EvaluationContext(targeting_key="user-123"),
)
