# Agent Schema Validation Test Suite

Comprehensive test coverage for the BMAD agent schema validation system.

## Overview

This test suite validates the Zod-based schema validator (`tools/schema/agent.js`) that ensures all `*.agent.yaml` files conform to the BMAD agent specification.

## Test Statistics

- **Total Test Fixtures**: 50
- **Valid Test Cases**: 18
- **Invalid Test Cases**: 32
- **Code Coverage**: 100% all metrics (statements, branches, functions, lines)
- **Exit Code Tests**: 4 CLI integration tests

## Quick Start

```bash
# Run all tests
npm test

# Run with coverage report
npm run test:coverage

# Run CLI integration tests
./test/test-cli-integration.sh

# Validate actual agent files
npm run validate:schemas
```

## Test Organization

### Test Fixtures

## Test Scripts

### Main Test Runner

**File**: `test/test-agent-schema.js`

Automated test runner that:

- Loads all fixtures from `test/fixtures/agent-schema/`
- Validates each against the schema
- Compares results with expected outcomes (parsed from YAML comments)
- Reports detailed results by category
- Exits with code 0 (pass) or 1 (fail)

**Usage**:

```bash
npm test
# or
node test/test-agent-schema.js
```

### Coverage Report

**Command**: `npm run test:coverage`

Generates code coverage report using c8:

- Text output to console
- HTML report in `coverage/` directory
- Tracks statement, branch, function, and line coverage

**Current Coverage**:

- Statements: 100%
- Branches: 100%
- Functions: 100%
- Lines: 100%

### CLI Integration Tests

**File**: `test/test-cli-integration.sh`

Bash script that tests CLI behavior:

1. Validates existing agent files
2. Verifies test fixture validation
3. Checks exit code 0 for valid files
4. Verifies test runner output format

**Usage**:

```bash
./test/test-cli-integration.sh
```

## Manual Testing

See **[MANUAL-TESTING.md](./MANUAL-TESTING.md)** for detailed manual testing procedures, including:

- Testing with invalid files
- GitHub Actions workflow verification
- Troubleshooting guide
- PR merge blocking tests

## Coverage Achievement

**100% code coverage achieved!** All branches, statements, functions, and lines in the validation logic are tested.

Edge cases covered include:

- Malformed module paths (e.g., `src/bmm` without `/agents/`)
- Empty module names in paths (e.g., `src/modules//agents/`)
- Whitespace-only module field values
- All validation error paths
- All success paths for valid configurations

## Adding New Tests

To add new test cases:

1. Create a new `.agent.yaml` file in the appropriate `valid/` or `invalid/` subdirectory
2. Add comment metadata at the top:

   ```yaml
   # Test: Description of what this tests
   # Expected: PASS (or FAIL - error description)
   # Path context: src/bmm/agents/test.agent.yaml (if needed)
   ```

3. Run the test suite to verify: `npm test`

## Integration with CI/CD

The validation is integrated into the GitHub Actions workflow:

**File**: `.github/workflows/lint.yaml`

**Job**: `agent-schema`

**Runs on**: All pull requests

**Blocks merge if**: Validation fails
