From c9b380c60110fe0464a7f4925a9be5d5aafb5937 Mon Sep 17 00:00:00 2001 From: Sergey Vanyushkin Date: Sun, 10 May 2026 14:08:23 +0300 Subject: [PATCH] test(api): add full API test suite with get_keycloak_client async fix Add 45 API tests covering all 12 post endpoints (CRUD, publish/unpublish) with RBAC policy coverage across guest, user, admin roles. Fix get_keycloak_client() in deps.py to be async - Dishka's async container requires await on get(), without it a coroutine object was returned instead of the actual client. --- app/presentation/api/deps.py | 8 +- tests/FEATURE_POST_LIFECYCLE.md | 196 +++++++- tests/FEATURE_RBAC.md | 18 +- tests/TEST_MODEL.md | 6 +- tests/api/__init__.py | 0 tests/api/conftest.py | 218 +++++++++ tests/api/test_posts.py | 788 ++++++++++++++++++++++++++++++++ 7 files changed, 1216 insertions(+), 18 deletions(-) create mode 100644 tests/api/__init__.py create mode 100644 tests/api/conftest.py create mode 100644 tests/api/test_posts.py diff --git a/app/presentation/api/deps.py b/app/presentation/api/deps.py index 12bad06..a6aff70 100644 --- a/app/presentation/api/deps.py +++ b/app/presentation/api/deps.py @@ -32,7 +32,7 @@ PublishPostDep = FromDishka[PublishPostUseCase] security = HTTPBearer(auto_error=False) -def get_keycloak_client(request: Request) -> KeycloakAuthClient: +async def get_keycloak_client(request: Request) -> KeycloakAuthClient: """Get Keycloak client from DI container via request state.
