From fbc61e893d691a912a718da1c8cdd0f35aed560d Mon Sep 17 00:00:00 2001 From: Andrew Harris Date: Thu, 7 Aug 2025 15:12:59 -0400 Subject: [PATCH 1/3] Add comprehensive tests for OAuth authentication system - Created a test module for OAuth authentication in backend/tests/test_auth_routes.py. - Implemented integration tests for the complete OAuth flow in backend/tests/test_integration.py. - Added unit tests for User model functionality in backend/tests/test_models.py. - Developed tests for OAuth service providers in backend/tests/test_oauth_services.py. - Introduced security edge case tests in backend/tests/test_security_edge_cases.py. - Established a test configuration in backend/tests/conftest.py for isolated testing. - Included tests for handling various OAuth scenarios, including error handling and edge cases. --- .github/workflows/test-oauth.yml | 154 ++++++++++ OAUTH_IMPLEMENTATION.md | 256 +++++++++++++++++ backend/Makefile | 108 +++++++ backend/SETUP_COMPLETE.md | 229 +++++++++++++++ backend/app/__init__.py | 53 ++++ backend/models/__init__.py | 6 + backend/models/user.py | 61 ++++ backend/pytest.ini | 24 ++ backend/requirements.txt | 15 + backend/routes/__init__.py | 7 + backend/routes/api.py | 15 + backend/routes/auth.py | 140 +++++++++ backend/run.py | 8 + backend/run_tests.sh | 82 ++++++ backend/services/__init__.py | 6 + backend/services/oauth.py | 258 +++++++++++++++++ backend/tests/README.md | 228 +++++++++++++++ backend/tests/__init__.py | 2 + backend/tests/conftest.py | 58 ++++ backend/tests/test_auth_routes.py | 297 +++++++++++++++++++ backend/tests/test_integration.py | 206 +++++++++++++ backend/tests/test_models.py | 161 +++++++++++ backend/tests/test_oauth_services.py | 336 ++++++++++++++++++++++ backend/tests/test_security_edge_cases.py | 285 ++++++++++++++++++ 24 files changed, 2995 insertions(+) create mode 100644 .github/workflows/test-oauth.yml create mode 100644 OAUTH_IMPLEMENTATION.md create mode 100644 backend/Makefile create mode 100644 backend/SETUP_COMPLETE.md create mode 100644 backend/models/user.py create mode 100644 backend/pytest.ini create mode 100644 backend/routes/api.py create mode 100644 backend/routes/auth.py create mode 100644 backend/run.py create mode 100755 backend/run_tests.sh create mode 100644 backend/services/oauth.py create mode 100644 backend/tests/README.md create mode 100644 backend/tests/conftest.py create mode 100644 backend/tests/test_auth_routes.py create mode 100644 backend/tests/test_integration.py create mode 100644 backend/tests/test_models.py create mode 100644 backend/tests/test_oauth_services.py create mode 100644 backend/tests/test_security_edge_cases.py diff --git a/.github/workflows/test-oauth.yml b/.github/workflows/test-oauth.yml new file mode 100644 index 0000000..f7592a5 --- /dev/null +++ b/.github/workflows/test-oauth.yml @@ -0,0 +1,154 @@ +name: ChargeBnB OAuth Authentication Tests + +on: + push: + branches: [ main, develop, '36-generate-project-structure' ] + paths: + -
