From 8c82d38d5b51e87118568534cbbaf2a03b2d78b8 Mon Sep 17 00:00:00 2001 From: Yossi Ovadia Date: Tue, 5 May 2026 12:17:46 -0700 Subject: [PATCH] test: add e2e-integration test suite for ExternalProvider/ExternalModel CRDs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a pytest-based integration test suite that validates the full inference gateway stack end-to-end: reconciler resource creation, Kuadrant auth enforcement, provider lifecycle, and error handling. All tests send real HTTP traffic through the gateway — no mocks. Standalone helpers (no MaaS repo imports) make the suite portable to any cluster with the required infrastructure. 32 passing tests, 7 xfail (multi-provider weights PR #213, migration controller not implemented). See test/e2e-integration/README.md for prerequisites, env vars, and instructions for both Kind and OpenShift. --- test/e2e-integration/.gitignore | 1 + test/e2e-integration/README.md | 121 +++++++++++ test/e2e-integration/conftest.py | 30 +++ test/e2e-integration/helpers.py | 107 ++++++++++ test/e2e-integration/requirements.txt | 2 + test/e2e-integration/test_auth.py | 203 ++++++++++++++++++ test/e2e-integration/test_lifecycle.py | 146 +++++++++++++ test/e2e-integration/test_migration.py | 97 +++++++++ test/e2e-integration/test_multiprovider.py | 84 ++++++++ test/e2e-integration/test_reconciler.py | 227 +++++++++++++++++++++ 10 files changed, 1018 insertions(+) create mode 100644 test/e2e-integration/.gitignore create mode 100644 test/e2e-integration/README.md create mode 100644 test/e2e-integration/conftest.py create mode 100644 test/e2e-integration/helpers.py create mode 100644 test/e2e-integration/requirements.txt create mode 100644 test/e2e-integration/test_auth.py create mode 100644 test/e2e-integration/test_lifecycle.py create mode 100644 test/e2e-integration/test_migration.py create mode 100644 test/e2e-integration/test_multiprovider.py create mode 100644 test/e2e-integration/test_reconciler.py diff --git a/test/e2e-integration/.gitignore b/test/e2e-integration/.gitignore new file mode 100644 index 00000000..c18dd8d8 --- /dev/null +++ b/test/e2e-integration/.gitignore @@ -0,0 +1 @@ +__pycache__/ diff --git a/test/e2e-integration/README.md b/test/e2e-integration/README.md new file mode 100644 index 00000000..7f388d30 --- /dev/null +++ b/test/e2e-integration/README.md @@ -0,0 +1,121 @@ +# E2E Integration Tests + +End-to-end integration tests for ExternalProvider/ExternalModel CRDs (`inference.opendatahub.io/v1alpha1`). + +These tests send **real HTTP requests** through the full gateway stack: +Envoy → Kuadrant/Authorino → BBR (payload-processing) → external model endpoint (llm-katan). + +No mocks, no unit test fakes — every test validates live cluster behavior. + +## What's Covered + +| Category | File | Tests | Status | +|----------|------|-------|--------| +| **Reconciler: resource creation** | `test_reconciler.py` | Provider creates Service, ServiceEntry, DestinationRule;
