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

# Run all tests

# 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 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:

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:

./test/test-cli-integration.sh

Manual Testing

See 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:

   # 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
