The import statement will fail: backend.api_contract and APIContract do not exist.

The backend directory is a Rust project with no Python modules. There is no backend/__init__.py, no backend/api_contract.py, and no Python API wrapper defined in the codebase. The test cannot run as written because the import will fail at runtime.

In `@tests/backend_api/test_api_contract.py` at line 2, The import statement for
APIContract from backend.api_contract will fail because the backend is a Rust

Rust backend, or if a Python API wrapper for the backend exists elsewhere in the
codebase, update the import statement to reference the correct module path where
APIContract is actually defined.

Add pytest-asyncio to project dependencies.

The @pytest.mark.asyncio decorator requires the pytest-asyncio package, which is not found in any dependency specification file (no requirements.txt, pyproject.toml, or setup.py exists in the repository). Add pytest-asyncio to your project dependencies to ensure this test runs correctly. Consider establishing a dependency management file if one doesn't exist (e.g., requirements.txt or pyproject.toml).

In `@tests/backend_api/test_api_contract.py` at line 13, The `@pytest.mark.asyncio`
decorator used in the test file requires the pytest-asyncio package as a
dependency, but it is not currently listed in any project dependency file.
Create or update the project's dependency management file (such as
requirements.txt or pyproject.toml) to include pytest-asyncio as a test
dependency, ensuring the asyncio marker will be available when tests are run.

⚠️ Potential issue | 🟠 Major | ⚖️ Poor tradeoff

The async test doesn't test meaningful async behavior.

This test wraps a synchronous APIContract.validate() call in an async helper, but this doesn't exercise any actual async edge cases or concurrency concerns. The test merely adds an artificial async wrapper around a synchronous operation, providing false confidence in async coverage without meaningful value.

If APIContract.validate() is truly synchronous and has no async variant, consider one of the following:

  1. Remove this test entirely if there's no async API to test.
  2. If the goal is to test validation in async contexts, test error handling: wrap the validate call in try/except within the async helper and assert the error is propagated correctly.
  3. Test concurrent validation with asyncio.gather() if that's a real use case.
🔄 Alternative: Test error handling in async context 
 `@pytest.mark.asyncio`
 async def test_api_contract_async_wrapper():
-    async def async_helper():
-        return APIContract.validate({"required_field": "value"})
-    result = await async_helper()
-    assert result == {"required_field": "value"}
+    async def async_helper(payload):
+        try:
+            return APIContract.validate(payload)
+        except APIContract.Error as e:
+            raise  # Ensure errors propagate correctly in async context
+    
+    # Test successful validation
+    result = await async_helper({"required_field": "value"})
+    assert result == {"required_field": "value"}
+    
+    # Test error propagation in async context
+    with pytest.raises(APIContract.Error):
+        await async_helper({"invalid": "payload"})

In `@tests/backend_api/test_api_contract.py` around lines 13 - 18, The test
function test_api_contract_async_wrapper does not exercise meaningful async
behavior; it merely wraps a synchronous APIContract.validate() call in an async
helper without testing any real async edge cases or concurrency concerns. Either
remove this test entirely if there is no actual async API variant to test, or
replace it with a test that validates meaningful async behavior such as error
handling (wrap the validate call in a try/except block and assert that
exceptions are properly propagated in the async context) or concurrent
validation using asyncio.gather() if that represents a real use case for your
application.
