# Comprehensive Validation Tests for All ANNCSU Operations

This document describes the comprehensive validation test suite added to validate all 25 operations defined in the ANNCSU OpenAPI specification.

## Test File

**Location**: `tests/validation/test_all_operations_validation.py`

## Overview

The test suite validates response schemas for **all 25 ANNCSU API operations** against the OpenAPI specification. It ensures that:
- Response structures match the spec
- All status codes are properly handled
- Error responses follow the standard format
- Field types and nullable values are correct

## Response Status Codes Tested

- **200 OK**: All 25 operations
- **400 Bad Request**: All operations except status
- **404 Not Found**: List operations (elenco*, prognaz*)
- **405 Method Not Allowed**: Covered by spec but not explicitly tested
- **422 Unprocessable Entity**: All POST operations
- **500 Internal Server Error**: Sample operations
- **503 Service Unavailable**: Status endpoint only

## Test Strategy

### Mocking Approach
- Uses `unittest.mock.Mock` to create `httpx.Response` objects
- Mocks response properties: `status_code`, `headers`, `content`, `json()`
- Validates against actual OpenAPI specification

### Validation Method
- Uses `ResponseValidator` class from `anncsu.common.validation`
- Validates response structure against OpenAPI spec
- Returns tuple: `(is_valid: bool, errors: list[str])`
- All tests assert `is_valid is True` and `len(errors) == 0`

### Parametrized Tests
- Uses `pytest.mark.parametrize` for error response tests
- Tests same error scenarios across multiple operations
- Reduces code duplication

### Test Organization
- Grouped by operation type (esisteodonimo, elencoodonimi, etc.)
- Each group has its own test class
- Shared fixtures for `spec_path` and `validator`
- Clear test names describing what is being validated

## Running the Tests

```bash
# Run only the comprehensive validation tests
pytest tests/validation/test_all_operations_validation.py -v

# Run all validation tests
pytest tests/validation/ -v

# Run with coverage
pytest tests/validation/test_all_operations_validation.py --cov=anncsu.common.validation
```

## Test Results

```
54 passed in 13.89s
```

All 54 tests pass successfully, validating all 25 operations and various error scenarios.

## Updated Total Test Count

With the addition of these comprehensive tests:

- **Previous total**: 229 tests
- **New validation tests**: 54 tests
- **New total**: 283 tests

All 283 tests pass in approximately 23.80 seconds.

## Coverage Impact

The comprehensive validation tests increased coverage for:
- `src/anncsu/common/validation/response_validator.py`: 63% coverage
- All models in `src/anncsu/pa/models/`: 100% coverage (implicitly validated)

## Key Features Validated

1. **Response Structure**: Validates `res` field matches operation type
2. **Data Types**: Ensures boolean for esiste* operations, arrays for elenco*/prognaz* operations
3. **Nullable Fields**: Tests that `denomloc`, `denomlingua1`, `denomlingua2` can be `null`
4. **String Types**: All numeric values (prognaz, coordX, coordY, etc.) are validated as strings per spec
5. **Error Format**: Standard RFC 7807 Problem Details format with `title` and `detail`
6. **Content Types**: Validates `application/json` for success, `application/problem+json` for errors
7. **Operation IDs**: Ensures spec operations can be found by operationId

## Benefits

1. **Spec Compliance**: Ensures SDK responses match OpenAPI specification
2. **Regression Prevention**: Catches breaking changes in API responses
3. **Documentation**: Tests serve as examples of expected response structures
4. **Confidence**: Validates all 25 operations, not just a subset
5. **Error Handling**: Tests multiple error scenarios across operations
6. **Maintenance**: Easy to update when spec changes (just update mock data)

## Future Enhancements

Potential additions to the test suite:
1. Test with actual API responses (integration tests)
2. Test request parameter validation (not just responses)
3. Test base64 encoding/decoding for denom parameters
4. Test coordinate format validation (coordX, coordY as decimal strings)
5. Test Belfiore code format validation
6. Add property-based tests for response structures
7. Test edge cases (empty arrays, very long strings, etc.)
