pytest-iam¶
pytest-iam spawns a lightweight OAuth2 / OpenID Server (OIDC) / SCIM in a thread to be used in your test suite. The machinery involves Canaille and Authlib.
Installation¶
uv add pytest-iam
Usage¶
pytest-iam provides tools to test your application authentication mechanism against a OAuth2/OIDC server, with SCIM support:
It launches a Canaille instance on a random port;
It provides a
iam_serverfixture that comes with several features:the URL of the IAM server to configure your application
IAM models (Users, groups, clients, tokens etc.) to prepare your tests and check the side effects. More details on the reference
utilities to log-in users and give their consent to your application
utilities to generate random users and groups
To run a full authentication process for a client application in your test, you can write something like this:
def test_authentication(iam_server, test_client):
# create a random user on the IAM server
user = iam_server.random_user()
# log the user in and make it consent all the clients
iam_server.login(user)
iam_server.consent(user)
# 1. attempt to access a protected page, returns a redirection to the IAM
res = test_client.get("/protected")
# 2. authorization code request
res = iam_server.test_client.get(res.location)
# 3. load your application authorization endpoint
res = test_client.get(res.location)
# 4. now you have access to the protected page
res = test_client.get("/protected")
assert "Hello, world!" in res.text
