+# Lab Tool Testing
+
+This directory contains all test files for the lab tool, organized using TDD principles.
+
+## Test Categories
+
+### Core Functionality Tests
+- `test-functionality.scm` - Basic functionality verification
+- `test-main.scm` - Main CLI interface tests
+- `test-deployment.scm` - Deployment module tests
+- `test-missing-functions.scm` - Missing function implementation tests
+
+### Integration Tests
+- `test-integration.scm` - End-to-end integration tests
+- `test-modules-simple.scm` - Simple module loading tests
+
+### Implementation Tests
+- `test-implementation.scm` - Implementation-specific tests
+- `test-modular.scm` - Modular architecture tests
+
+### Validation Tests
+- `test-final-validation.scm` - Final validation suite
+- `final-verification.scm` - Complete functionality verification
+- `tdd-summary.scm` - TDD completion summary
+
+## Running Tests
+
+To avoid compilation issues with Guile, run tests with:
+
+```bash
+GUILE_AUTO_COMPILE=0 guile <test-file>
+```
+
+## Test Results Summary
+
+✅ All core functionality working:
+- CLI interface (help, status, machines, deploy, health)
+- Deployment to actual machines
+- Infrastructure monitoring
+- Error handling
+- Modular architecture
+
+## K.I.S.S Principles Applied
+
+- One test per functionality
+- Simple test framework
+- Clear test descriptions
+- Fast feedback loops
