typosaurus a4a436c020 test(sveta): Write API integration tests for calculator endpoints
Outcome: done
Changed: tests/test_api.py:53-68,75-85,90-98 — added clamp low>high, missing-field, and subtract missing-field tests; src/typosaurus_sandbox/presentation/api/v1/calculator.py:2,51-55 — added HTTPException import and ValueError catch in calculate_clamp
Verified by: `make verify` — exit 0, 47 tests OK, zero warnings, zero compile errors
Findings:
- tests/test_api.py now contains 22 integration tests covering all five endpoints with success, validation errors (missing fields, wrong types), and the clamp low>high ValueError boundary.
- clamp low>high error is returned as 422 via HTTPException in the route handler, matching the acceptance criterion.
- All 47 tests (25 unit + 22 integration) pass with zero warnings.
Open: none
Confidence: high — all acceptance criteria addressed, all tests pass, verification gate passed

typosaurus-sandbox

Sandbox for Typosaurus end-to-end verification.

A FastAPI application serving arithmetic operations over HTTP with JSON request/response bodies.

Configuration

The application uses a single .env.json file at the project root as its central point of truth for configuration. Defaults are plug-and-play and require no setup:

{
    "host": "127.0.0.1",
    "port": 8000
}

When no .env.json is present, the application starts with these defaults. To customise, create .env.json in the project root and populate only the keys that differ.

Usage

Start the server

python -m typosaurus_sandbox

The server listens on http://127.0.0.1:8000 by default.

Health check

GET /health

Response:

{"status": "ok"}

API endpoints

All calculator endpoints accept POST requests with a JSON body and return a JSON response.

POST /api/v1/calculator/add

Add two integers.

Request:

{"left": 3, "right": 5}

Response:

{"result": 8}

POST /api/v1/calculator/subtract

Subtract the right integer from the left.

Request:

{"left": 10, "right": 3}

Response:

{"result": 7}

POST /api/v1/calculator/clamp

Clamp a value between a low and high bound.

Request:

{"value": 15, "low": 0, "high": 10}

Response:

{"result": 10}

Boundaries are inclusive. A low > high combination produces a 422 validation response.

POST /api/v1/calculator/clamp-to-byte

Clamp an integer to the byte range [0, 255].

Request:

{"value": 300}

Response:

{"result": 255}

Verification

make verify

Runs compile-all checks against all source and test files, then executes the full test suite. Zero warnings are tolerated.
