Overview

The Unix socket server package includes a comprehensive test suite designed to validate functionality, performance, concurrency safety, and robustness under various conditions. The test suite uses BDD (Behavior-Driven Development) style with Ginkgo v2 and Gomega for clear, readable tests.

Test Philosophy:

1. Atomic Testing: Each test validates a single behavior
2. Concurrency Safety: All tests run with race detector
3. Real Resources: Use actual Unix domain sockets, no mocks
4. Performance Aware: Measure and validate performance characteristics
5. Comprehensive Coverage: Target >80% code coverage with meaningful tests
6. Platform-Specific: Tests for Linux and macOS platforms only

Framework & Tools

Ginkgo v2 - BDD Testing Framework

Why Ginkgo over standard Go testing:

• ✅ Hierarchical organization: Describe, Context, It for clear test structure
• ✅ Better readability: Tests read like specifications
• ✅ Rich lifecycle hooks: BeforeEach, AfterEach, BeforeAll, AfterAll
• ✅ Async testing: Eventually, Consistently for time-based assertions
• ✅ Parallel execution: Built-in support for concurrent test runs
• ✅ Focused/Pending specs: Easy debugging with FIt, FDescribe
• ✅ Better reporting: Colored output, progress indicators

Reference: Ginkgo Documentation

Example:

var _ = Describe("Unix Socket Server", func() {
    Context("when starting", func() {
        It("should accept connections", func() {
            // Test logic
        })
    })
})

Gomega - Matcher Library

Advantages over standard assertions:

• ✅ Expressive matchers: Equal, BeNumerically, HaveOccurred, etc.
• ✅ Better error messages: Clear failure descriptions
• ✅ Async assertions: Eventually for polling conditions
• ✅ Custom matchers: Extensible for domain-specific assertions

Reference: Gomega Documentation

Example matchers:

Expect(err).ToNot(HaveOccurred())
Expect(srv.IsRunning()).To(BeTrue())
Expect(count).To(Equal(int64(5)))
Eventually(func() bool {
    return srv.IsRunning()
}, 2*time.Second).Should(BeTrue())

gmeasure - Performance Measurement

Why gmeasure:

• ✅ Statistical analysis: Automatic calculation of median, mean, percentiles
• ✅ Integrated reporting: Results embedded in Ginkgo output
• ✅ Sampling control: Configurable sample size and duration
• ✅ Multiple metrics: Duration, memory, custom measurements

Reference: gmeasure Package

Example:

exp := NewExperiment("Server Performance")
exp.Sample(func(idx int) {
    exp.MeasureDuration("startup", func() {
        // Code to measure
    })
}, SamplingConfig{N: 10})

stats := exp.GetStats("startup")
// Provides: Min, Max, Median, Mean, StdDev

Uncovered Code Analysis

High Coverage (>80%):

interface.go:   91.7%  ✅  Server creation and initialization
listener.go:    84.1%  ✅  Accept loop and connection handling  
model.go:       86.7%  ✅  Core server state management
error.go:       100%   ✅  Error definitions

Medium Coverage (60-80%):

context.go:     61.5%  ⚠️   I/O operations and context management

Uncovered Lines: 20.9% (target: <20%)

1. Context Interface Methods (0% coverage)

These are standard context.Context interface implementations that delegate to the underlying context. Low priority for testing as they're thin wrappers:

func (o *sCtx) Deadline() (time.Time, bool)  // 0%
func (o *sCtx) Done() <-chan struct{}         // 0%
func (o *sCtx) Err() error                    // 0%
func (o *sCtx) Value(key any) any             // 0%

Reason: Thin wrappers around embedded context, tested indirectly through integration tests.

Impact: Low - defensive programming for standard interface compliance.

2. Connection State Methods (0% coverage)

Simple accessor methods:

func (o *sCtx) IsConnected() bool     // 0%
func (o *sCtx) RemoteHost() string    // 0%
func (o *sCtx) LocalHost() string     // 0%

Reason: Simple getters, minimal logic to test.

Impact: Minimal - straightforward accessor methods.

3. Error Handling Edge Cases

Partial coverage on error paths:

• Write error combinations: 61.5%
• Close error handling: 70%
• Error callback invocation: 53.8%

Reason: Difficult to trigger specific error conditions in integration tests.

Impact: Low - error paths are defensive, core functionality is well-tested.

• Recommended limit: 1,000-10,000 connections
• Not suitable for: >50,000 simultaneous connections

Concurrency Performance

Concurrent Operations:

Test	Goroutines	Operations	Time	Throughput	Races
Concurrent Connections	10	100	~200ms	500 conn/s	0
Concurrent Start/Stop	5	50	~1s	50 ops/s	0
Echo Operations	10	1000	~2s	500 ops/s	0

Scalability:

• ✅ Linear scaling up to 100 connections
• ✅ No lock contention (atomic operations)
• ✅ No performance degradation under load
• ✅ Zero race conditions detected

Memory Usage

Per-Connection Memory:

Goroutine stack:      ~8 KB
sCtx structure:       ~1 KB
Application buffers:  Variable (e.g., 4 KB)
────────────────────────────
Total per connection: ~10-15 KB

Memory Scaling:

Connections	Memory Usage	Notes
100	~1-2 MB	Ideal range
1,000	~10-15 MB	Good
10,000	~100-150 MB	Monitor closely
50,000+	~500MB-1GB+	Not recommended

Test Templates

Basic Unit Test Template

var _ = Describe("Component", func() {
    var (
        srv scksru.ServerUnix
        ctx context.Context
        cancel context.CancelFunc
    )

    BeforeEach(func() {
        // Setup
        ctx, cancel = context.WithCancel(globalCtx)
        cfg := createDefaultConfig(getTestSocketPath())
        srv, _ = scksru.New(nil, echoHandler, cfg)
    })

    AfterEach(func() {
        // Cleanup
        if srv != nil {
            _ = srv.Close()
        }
        if cancel != nil {
            cancel()
        }
        time.Sleep(50 * time.Millisecond)  // Allow cleanup
    })

    Context("when doing X", func() {
        It("should behave Y", func() {
            // Test logic with Expect assertions
        })
    })
})

Helper Functions

Common Helpers in helper_test.go:

// Get a free TCP port
port := getFreePort()

// Get test address with free port
addr := getTestAddr()  // "localhost:XXXXX"

// Create default configuration
cfg := createDefaultConfig(addr)

// Create TLS configuration
cfg := createTLSConfig(addr)

// Connect to server
conn := connectToServer(addr)

// Send and receive data
response := sendAndReceive(conn, data)

// Wait for server state
waitForServer(srv, 2*time.Second)
waitForServerStopped(srv, 2*time.Second)
waitForConnections(srv, 5, 2*time.Second)

// Start server in background
startServerInBackground(ctx, srv)

Handler Functions:

echoHandler(c libsck.Context)                 // Echo server
counterHandler(cnt *atomic.Int32)             // Count connections
slowHandler(delay time.Duration)              // Delayed handler
closeHandler(c libsck.Context)                // Immediately close
writeOnlyHandler(msg string)                  // Write-only
readOnlyHandler(c libsck.Context)             // Read-only

Running New Tests

Focus on Specific Tests:

# Run only new tests by pattern
go test -run TestNewFeature -v

# Run specific Ginkgo spec
go test -ginkgo.focus="should handle new feature" -v

# Run tests in specific file (requires build tags or focus)
go test -run TestServerTCP/NewFeature -v

Fast Validation Workflow:

# 1. Run only the new test (fast)
go test -ginkgo.focus="new feature" -v

# 2. If passes, run full suite without race (medium)
go test -v

# 3. If passes, run with race detector (slow)
CGO_ENABLED=1 go test -race -v

# 4. Check coverage impact
go test -cover -coverprofile=coverage.out
go tool cover -func=coverage.out | grep "new_feature"

Debugging New Tests:

# Verbose output with stack traces
go test -v -ginkgo.v -ginkgo.trace

# Focus and fail fast
go test -ginkgo.focus="new feature" -ginkgo.failFast -v

# With delve debugger
dlv test -- -ginkgo.focus="new feature"

Benchmark Template

Using gmeasure:

var _ = Describe("Benchmarks", Ordered, func() {
    var experiment *gmeasure.Experiment

    BeforeAll(func() {
        experiment = gmeasure.NewExperiment("Operation Name")
        AddReportEntry(experiment.Name, experiment)
    })

    It("should measure performance", func() {
        experiment.Sample(func(idx int) {
            experiment.MeasureDuration("operation", func() {
                // Code to benchmark
            })
        }, gmeasure.SamplingConfig{
            N:        100,              // Sample size
            Duration: 5 * time.Second,  // Max duration
        })

        stats := experiment.GetStats("operation")
        AddReportEntry("Stats", stats)
        
        // Assert performance requirements
        Expect(stats.DurationFor(gmeasure.StatMedian)).To(
            BeNumerically("<", 10*time.Millisecond))
    })
})

Best Practices:

1. Warmup: Run operations before measuring to stabilize
2. Realistic Load: Use production-like data sizes
3. Clean State: Reset between samples if needed
4. Statistical Significance: Use N >= 50 for reliable results
5. Timeout: Always set reasonable duration limits
6. Assertions: Be tolerant (use P50/P95, not min/max)

Best Practices

✅ DO

1. Use free ports:

// ✅ GOOD: Avoid port conflicts
addr := getTestAddr()  // Gets a free port

2. Cleanup resources:

// ✅ GOOD: Always cleanup
defer srv.Close()
defer cancel()
time.Sleep(50 * time.Millisecond)  // Allow goroutines to finish

3. Use Eventually for async operations:

// ✅ GOOD: Wait for async state changes
Eventually(func() bool {
    return srv.IsRunning()
}, 2*time.Second, 10*time.Millisecond).Should(BeTrue())

4. Test error paths:

// ✅ GOOD: Test both success and failure
It("should fail with invalid address", func() {
    cfg := createDefaultConfig("")
    srv, err := scksrt.New(nil, handler, cfg)
    Expect(err).To(HaveOccurred())
    Expect(srv).To(BeNil())
})

❌ DON'T

1. Don't hardcode ports:

// ❌ BAD: Port conflict in parallel tests
cfg := createDefaultConfig(":8080")

2. Don't forget cleanup:

// ❌ BAD: Resource leak
srv, _ := scksrt.New(nil, handler, cfg)
// Forgot to call srv.Close()

3. Don't use fixed delays for state:

// ❌ BAD: Flaky due to timing
time.Sleep(100 * time.Millisecond)
Expect(srv.IsRunning()).To(BeTrue())

// ✅ GOOD: Use Eventually
Eventually(srv.IsRunning, 2*time.Second).Should(BeTrue())

4. Don't test implementation details:

// ❌ BAD: Tests internal structure
Expect(srv.(*tcp.srv).run.Load()).To(BeTrue())

// ✅ GOOD: Test public API
Expect(srv.IsRunning()).To(BeTrue())

Troubleshooting

Common Issues

1. Race Detector Errors

WARNING: DATA RACE

Solution:

• Run with -race flag: CGO_ENABLED=1 go test -race
• Fix any detected races (use atomic operations, mutexes, or channels)
• All tests must pass with race detector

2. Port Already in Use

bind: address already in use

Solution:

• Use getTestAddr() to get free ports
• Ensure proper cleanup in AfterEach
• Add time.Sleep() after server close to allow OS to release port

3. Timeout in Eventually

Timed out after 2.000s

Solution:

• Increase timeout: Eventually(..., 5*time.Second)
• Check if server is actually starting
• Verify no errors in server startup
• Use waitForServerAcceptingConnections() for network readiness

4. Flaky Tests

Symptoms: Tests pass sometimes, fail other times

Solutions:

• Remove fixed time.Sleep(), use Eventually()
• Ensure unique ports per test (getTestAddr())
• Proper resource cleanup
• Avoid testing timing-dependent behavior

5. Coverage Not Updating

# Ensure coverage file is generated
go test -coverprofile=coverage.out ./...

# Check file exists
ls -lh coverage.out

# View coverage
go tool cover -func=coverage.out

Performance Test Failures

Startup too slow (>1s):

• Check system load
• Verify no network issues
• Ensure ports are available quickly

Echo latency too high (>50ms):

• Use localhost (not external interfaces)
• Check for CPU throttling
• Verify no network congestion
