# 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
Located in `test/fixtures/agent-schema/`, organized by category:
```

- ✅ Valid: Complete persona with all fields
- ❌ Invalid: Missing required fields (`role`, `identity`, etc.)
- ❌ Invalid: `principles` as string instead of array
- ❌ Invalid: Empty `principles` array
- ❌ Invalid: Empty strings in `principles` array
- ❌ Invalid: Extra unknown persona fields
### 4. Critical Actions Tests (5 fixtures)
Tests optional `critical_actions` field:
- ✅ Valid: No `critical_actions` field (optional)
- ✅ Valid: Empty `critical_actions` array
- ✅ Valid: Valid action strings
- ❌ Invalid: Empty strings in actions
- ❌ Invalid: Actions as non-array type
### 5. Menu Field Tests (4 fixtures)
Tests required menu structure:
- ✅ Valid: Single menu item
- ✅ Valid: Multiple menu items with different commands
- ❌ Invalid: Missing `menu` field
- ❌ Invalid: Empty `menu` array
### 6. Menu Command Target Tests (4 fixtures)
Tests menu item command targets:
- ✅ Valid: All 6 command types (`workflow`, `validate-workflow`, `exec`, `action`, `tmpl`, `data`)
- ✅ Valid: Multiple command targets in one menu item
- ❌ Invalid: No command target fields
- ❌ Invalid: Empty string command targets
### 7. Menu Trigger Validation Tests (7 fixtures)
Tests trigger format enforcement:
- ✅ Valid: Kebab-case triggers (`help`, `list-tasks`, `multi-word-trigger`)
- ❌ Invalid: Leading asterisk (`*help`)
- ❌ Invalid: CamelCase (`listTasks`)
- ❌ Invalid: Snake_case (`list_tasks`)
- ❌ Invalid: Spaces (`list tasks`)
- ❌ Invalid: Duplicate triggers within agent
- ❌ Invalid: Empty trigger string
### 8. Prompts Field Tests (8 fixtures)
Tests optional `prompts` field:
- ✅ Valid: No `prompts` field (optional)
- ✅ Valid: Empty `prompts` array
- ✅ Valid: Prompts with required `id` and `content`
- ✅ Valid: Prompts with optional `description`
- ❌ Invalid: Missing `id`
- ❌ Invalid: Missing `content`
- ❌ Invalid: Empty `content` string
- ❌ Invalid: Extra unknown prompt fields
### 9. YAML Parsing Tests (2 fixtures)
Tests YAML parsing error handling:
- ❌ Invalid: Malformed YAML syntax
- ❌ Invalid: Invalid indentation
## 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/modules/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/modules/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
