From e767920407cda6b73217731837ec1960409a5214 Mon Sep 17 00:00:00 2001 From: Felipe Cardoso Date: Thu, 30 Oct 2025 17:54:14 +0100 Subject: [PATCH] Add extensive tests for user routes, CRUD error paths, and coverage configuration - Implemented comprehensive tests for user management API endpoints, including edge cases, error handling, and permission validations. - Added CRUD tests focusing on exception handling in database operations, soft delete, and update scenarios. - Introduced custom `.coveragerc` for enhanced coverage tracking and exclusions. - Improved test reliability by mocking rate-limiting configurations and various database errors. --- backend/.coveragerc | 68 +++ backend/tests/api/test_user_routes.py | 546 ++++++++++++++++++++ backend/tests/crud/test_crud_error_paths.py | 295 +++++++++++ 3 files changed, 909 insertions(+) create mode 100644 backend/.coveragerc create mode 100644 backend/tests/api/test_user_routes.py create mode 100644 backend/tests/crud/test_crud_error_paths.py diff --git a/backend/.coveragerc b/backend/.coveragerc new file mode 100644 index 0000000..d91a645 --- /dev/null +++ b/backend/.coveragerc @@ -0,0 +1,68 @@ +[run] +source = app +omit = + #
