+# Testing tfmod-eks-configuration
+
+This directory contains tests for the EKS configuration module.
+
+## Test Structure
+
+```
+tests/
+├── fixtures/            # Test configurations
+│   ├── complete/       # Complete example for integration tests
+│   └── validation/     # Validation test cases
+├── integration/        # Integration tests
+└── unit/              # Unit tests
+```
+
+## Running Tests
+
+### Prerequisites
+- Go 1.16 or later
+- AWS credentials configured
+- kubectl configured
+- Existing EKS cluster
+
+### Unit Tests
+Test input validation and parameter checking:
+```bash
+cd tests/unit
+go test -v ./...
+```
+
+### Integration Tests
+Test actual resource creation and configuration:
+```bash
+cd tests/integration
+go test -v ./... -timeout 30m
+```
+
+## Test Cases
+
+### Unit Tests
+- Input validation for VPC ID format
+- Subnet count validation
+- Namespace name validation
+- Tag validation
+
+### Integration Tests
+- Storage class creation and configuration
+- EFS filesystem provisioning
+- Network policy application
+- Operator namespace setup
+
+## Adding New Tests
+
+1. Create test fixtures in `fixtures/`
+2. Add test cases in `unit/` or `integration/`
+3. Update test documentation
+4. Run tests locally before committing
+
+## Cleanup
+
+The test framework automatically cleans up resources, but you can manually run:
+```bash
+cd tests/fixtures/complete
+terraform destroy
+```
