Fix Testing Suites & Async Execution Issues

[RohanExploit]

This submission resolves multiple issues across the testing suites in both the backend and frontend:

1. Backend Tests: Addressed async def and @pytest.mark.asyncio usages in synchronous TestClient tests, which caused tests to fail natively.
2. Pytest Configurations: Installed pytest-asyncio and configured pytest.ini with asyncio_mode = auto and asyncio_default_fixture_loop_scope = function to gracefully handle backend asynchronous test setups and fixtures without throwing deprecation warnings.
3. Endpoint Routing Fixes: Updated affected API route tests (e.g., /detect-waste, /detect-vandalism, /detect-severity) to point to the correct global /api/ prefix as defined in backend/main.py.
4. Frontend Jest Execution: Added necessary Babel and TypeScript configurations (babel-plugin-transform-vite-meta-env, ts-jest, @types/jest) to allow frontend test files with Vite's import.meta.env to parse and pass without module resolution errors.

Summary by cubic

Fixes failing backend tests and frontend Jest runs by correcting async usage, aligning test routes to the /api/* prefix, and adding required test configs. Restores green CI and removes asyncio warnings.

• Bug Fixes

  • Converted @pytest.mark.asyncio tests to sync for TestClient.
  • Updated test URLs to /api/detect-* and /api/transcribe-audio.

• Dependencies

  • Added pytest-asyncio and configured pytest.ini for auto asyncio mode.
  • Added babel-plugin-transform-vite-meta-env, ts-jest, and @types/jest to let Jest parse import.meta.env and TypeScript.

^{Written for commit c051edf. Summary will update on new commits.}

Summary by CodeRabbit

• Tests
  • Updated test suite to use standardized /api path prefix across all backend API endpoints.
  • Refactored test functions for improved execution compatibility.

📝 Walkthrough

Walkthrough

Test files are being refactored to convert async test functions to synchronous variants and update API endpoints to use a standardized /api path prefix. All test logic, mocking, and assertions remain unchanged; only the execution model and endpoint routing are modified.

Changes

Cohort / File(s)	Summary
Async-to-Sync Conversion with Path Updates backend/tests/test_detection_bytes.py, backend/tests/test_severity.py	Removed @pytest.mark.asyncio decorators and converted test functions from async def to def. Updated API paths to include /api prefix (/detect-vandalism → /api/detect-vandalism, /detect-severity → /api/detect-severity).
Async-to-Sync Conversion backend/tests/test_new_detectors.py	Removed @pytest.mark.asyncio decorators and converted test functions test_detect_traffic_sign_damaged, test_detect_traffic_sign_clear, and test_detect_abandoned_vehicle_found from async def to def.
Path Updates backend/tests/test_new_features.py	Updated API endpoint paths to use /api prefix: /detect-waste → /api/detect-waste, /detect-civic-eye → /api/detect-civic-eye, /transcribe-audio → /api/transcribe-audio.

Pull request overview

This PR aims to stabilize the backend test suite by aligning tests with how FastAPI’s synchronous TestClient executes async endpoints, and by correcting test URLs to match the app’s /api router prefix.

Changes:

• Converted several tests from async def / @pytest.mark.asyncio to synchronous tests using TestClient.
• Updated multiple detection endpoint test calls to use the /api/... URL prefix.
