feat: Add refactored Go SDK with comprehensive tests and documentation #3

rhoninl · 2025-10-27T05:49:44Z

This commit introduces a professional, production-ready Go SDK for Shifu IoT device management with significant architectural improvements.

Major Changes:

Refactored from global state to Client-based architecture
Added dependency injection for better testability
Introduced interfaces (EdgeDeviceClient, ConfigLoader, HealthChecker)
Comprehensive test suite with 78.9% coverage
Professional README.md with examples and API reference

New Features:

Client struct with NewClient() and NewClientFromEnv() constructors
Support for multiple device management with isolated instances
Flexible configuration via Config struct
Health monitoring with customizable intervals
ConfigMap configuration loading with generic type support
Backward compatible deprecated global functions

Architecture Improvements:

Eliminated global state variables
Better error handling with wrapped errors
Type-safe API with proper Go idioms
Testable design with mock support
Clear separation of concerns

Documentation:

Comprehensive README.md based on Python SDK structure
Quick start examples and usage patterns
Complete API reference
Troubleshooting guide
Migration guide from deprecated functions

Testing:

78.9% test coverage with comprehensive test suite
Mock HTTP servers for Kubernetes API testing
Unit tests for all major functions
Edge case and error handling tests
Benchmark tests included

Files Added:

sdk.go: Main SDK implementation with Client API
sdk_test.go: Comprehensive test suite
README.md: Professional documentation
go.mod: Module dependencies
go.sum: Dependency checksums

+    token: test-token
+`
+
+	os.WriteFile(kubeconfigPath, []byte(kubeconfigContent), 0644)


The error from os.WriteFile is not being checked. While this is in a test setup, ignoring the error could lead to confusing test failures if the file write fails. Consider checking and handling the error: if err := os.WriteFile(...); err != nil { t.Fatalf(...) }.

Suggested change

os.WriteFile(kubeconfigPath, []byte(kubeconfigContent), 0644)

if err := os.WriteFile(kubeconfigPath, []byte(kubeconfigContent), 0644); err != nil {

t.Fatalf("failed to write kubeconfig: %v", err)

}

+      protocol: "http"
+      address: "/api"
+`
+	os.WriteFile(tmpFile, []byte(content), 0644)


The error from os.WriteFile is not being checked in this benchmark setup. If the file write fails, the benchmark will produce misleading results. Consider checking the error: if err := os.WriteFile(...); err != nil { b.Fatal(err) }.

Suggested change

os.WriteFile(tmpFile, []byte(content), 0644)

if err := os.WriteFile(tmpFile, []byte(content), 0644); err != nil {

b.Fatal(err)

}

+	server := httptest.NewServer(http.HandlerFunc(handler))
+	defer server.Close()
+
+	v1alpha1.AddToScheme(scheme.Scheme)


The error from v1alpha1.AddToScheme is not being checked in this benchmark. If adding to the scheme fails, subsequent operations will fail in confusing ways. Consider checking the error or documenting why it's safe to ignore in this context.

Suggested change

v1alpha1.AddToScheme(scheme.Scheme)

if err := v1alpha1.AddToScheme(scheme.Scheme); err != nil {

b.Fatalf("failed to add v1alpha1 to scheme: %v", err)

}

+
+	restClient, _ := rest.UnversionedRESTClientFor(config)


The error from rest.UnversionedRESTClientFor is being explicitly ignored with _. In a benchmark, if client creation fails, the benchmark results will be invalid. Consider handling this error: if err != nil { b.Fatal(err) }.

Suggested change

restClient, _ := rest.UnversionedRESTClientFor(config)

restClient, err := rest.UnversionedRESTClientFor(config)

if err != nil {

b.Fatal(err)
