`.env` file is already included in `.gitignore` to prevent accidental credential commits. + +## Test Philosophy + +### Unit Tests +- **Focus**: Resource validation and configuration testing using standard Go testing +- **Scope**: API-specific functionality differences +- **Dependencies**: None (no external dependencies) +- **Execution**: Fast execution suitable for CI/CD +- **Framework**: Standard Go `testing` package with `t.Run()` for subtests + +### Integration Tests +- **Focus**: Actual connectivity to Nutanix infrastructure +- **Scope**: Environment configuration and API access validation +- **Dependencies**: Requires live Nutanix environment +- **Execution**: Longer execution time with network calls +- **Safety**: Non-destructive testing (no VM creation) +- **Framework**: Standard Go `testing` package with `TestMain` for setup + +## Test Structure and Patterns + +### Unit Test Pattern +```go +func TestFeatureName(t *testing.T) { + // Setup test data + testData := createTestData() + + // Execute test logic + result := functionUnderTest(testData) + + // Validate results + if result != expectedValue { + t.Errorf("Expected %v, got %v", expectedValue, result) + } +} +``` + +### Integration Test Pattern +```go +func TestIntegrationFeature(t *testing.T) { + t.Run("SpecificAspect", func(t *testing.T) { + // Test specific aspect + result, err := apiCall() + if err != nil { + t.Fatalf("Unexpected error: %v", err) + } + // Validate result + }) +} +``` + +### Subtest Pattern +```go +func TestMultipleScenarios(t *testing.T) { + testCases := []struct { + name string

TestNutanixMachineResourceCreation +``` + +## Relationship to E2E Tests + +These tests complement the full e2e test suite: + +- **Unit Tests**: Fast, isolated validation of resource specifications +- **Integration Tests**: Environment and connectivity validation +- **E2E Tests**: Full lifecycle testing including actual VM creation + +The separation allows for: +- **Development Feedback**: Quick feedback during development (unit tests) +- **Environment Validation**: Verify environment setup (integration tests) +- **System Validation**: Full system validation (e2e tests) + +## Benefits of Standard Go Testing + +### Advantages over Ginkgo/Gomega: +- **Simplicity**: No additional framework dependencies +- **Performance**: Faster execution without framework overhead +- **Tooling**: Better integration with standard Go tooling +- **Debugging**: Easier debugging with standard Go debugger +- **CI/CD**: Simpler CI/CD integration +- **Learning Curve**: Lower learning curve for Go developers + +### Standard Features Used: +- `testing.T` for test functions +- `t.Run()` for subtests and parallel execution +- `t.Error()` and `t.Errorf()` for test failures +- `t.Fatal()` and `t.Fatalf()` for critical failures +- `t.Skip()` for conditional test skipping +- `TestMain()` for test setup and teardown +- Build tags (`//go:build integration`) for test categorization + +## Adding New Tests + +### For V3-specific functionality: +- Add test functions to `v3_test.go` +- Use prefix `TestV3` for function names +- Follow existing patterns and naming conventions +- Focus on V3 API specific behaviors + +### For V4-specific functionality: +- Add test functions to `v4_test.go` +- Use prefix `TestV4` for function names +- Test V4 enhanced features and capabilities +- Include V4-specific validation logic + +### For cross-API functionality: +- Add test functions to `integration_test/vmready_integration_test.go` +- Test environment and connectivity aspects +- Ensure tests remain safe and non-destructive +- Use subtests for different aspects of functionality + +### Test Function Naming: +- Unit tests: `Test[V3|V4]` +- Integration tests: `Test` +- Subtests: Use descriptive names with `t.Run("SubtestName", func(t *testing.T) {...})` + +## Coverage and Quality + +### Running Coverage: +```bash +# Unit test coverage +cd controllers/nutanixmachine +go test -v . -cover + +# Integration test coverage +cd controllers/nutanixmachine/integration_test +go test -tags=integration -v . -cover + +# Generate detailed coverage report +go test -v . -coverprofile=coverage.out +go tool cover -html=coverage.out -o coverage.html +``` + +### Test Quality Guidelines: +- **Clear naming**: Test function names should clearly indicate what is being tested +- **Focused scope**: Each test should test one specific behavior +- **Error messages**: Use descriptive error messages with expected vs actual values +- **Setup/teardown**: Use `TestMain` for integration test setup +- **Subtests**: Use

Nutanix APIs appropriately +4. **Error Handling**: Test graceful handling of missing infrastructure or configuration errors +5. **Logic Flow**: Verify the reconciliation logic flows correctly through different scenarios + +### Expected Outcomes +- Tests may fail if the specified infrastructure (clusters, subnets, images) doesn't exist - this is expected +- The goal is to verify that the reconciliation functions handle these scenarios gracefully +- Tests should complete without panics or crashes +- Reconciliation should attempt to process resources and handle errors appropriately +

Client Initialization Success +**Behavior**: V4 tests run when V4 client initializes successfully +**Note**: V4 client uses the same credentials as V3 but with facade interface + +## Relationship to Other Tests + +These integration tests complement: + +- **Unit Tests** (`../v3_test.go`, `../v4_test.go`): Fast, isolated validation of resource specifications +- **Controller Tests**: Full controller lifecycle testing +- **E2E Tests**: Complete cluster lifecycle with actual VM creation + +The integration tests bridge the gap by: +- Testing reconciliation functions with real API clients +- Validating API connectivity and authentication +- Verifying reconciliation logic without infrastructure changes +- Providing confidence in reconciliation behavior before E2E testing + +## Adding New Tests + +### For New V3 Reconciliation Scenarios +Add test functions to `TestV3NutanixMachineVMReadyReconciliation`: +```go +t.Run("V3NewScenario", func(t *testing.T) { + // Create test resources with

do not create, modify, or delete actual VMs +- Tests do not modify Nutanix infrastructure +- Tests only call reconciliation functions to verify logic flow +- Safe to run against production Nutanix environments (with appropriate caution) + +### Data Protection +- Tests use fake Kubernetes client to avoid affecting real clusters +- Environment variables should be set to test/development Nutanix environment when possible +- No persistent state changes in Nutanix infrastructure + +## Benefits + +1. **Reconciliation Logic Validation**: Tests actual reconciliation function behavior +2. **API Client Integration**: Verifies real Nutanix client integration +3. **Error Handling**: Tests graceful handling of various failure scenarios +4. **Configuration Validation**: Tests different
