😤

The Problem

Writing API tests is tedious and incomplete. Developers test the happy path, skip edge cases, and miss security scenarios entirely. When you finally have tests, they're brittle and break with every API change. Manual test maintenance eats hours every sprint.

✨

The Solution

This agent reads your OpenAPI spec, understands your API's structure, and generates comprehensive test suites covering success paths, error conditions, boundary values, and security scenarios. Tests are structured, maintainable, and update when your spec changes.

Example Input & Output

Input

OpenAPI Spec: /api/v1/users
Methods: GET (list), POST (create), GET /:id, PUT /:id, DELETE /:id
Auth: Bearer token
Rate limit: 100 req/min

Output

Generated: 34 test cases across 5 endpoints

```python
class TestUsersAPI:
    def test_create_user_success(self, client, auth_headers):
        response = client.post("/api/v1/users",
            json={"email": "test@example.com", "name": "Test"},
            headers=auth_headers)
        assert response.status_code == 201
        assert "id" in response.json()

    def test_create_user_duplicate_email(self, client, auth_headers):
        # Should return 409 Conflict
        ...

    def test_create_user_no_auth(self, client):
        # Should return 401 Unauthorized
        ...

    def test_rate_limit_exceeded(self, client, auth_headers):
        # Should return 429 after 100 requests
        ...
```

📊 Coverage: 100% of endpoints, 95% of status codes
