## π― Testing Philosophy
### π Rule 15 Testing Principles
Our testing strategy strictly adheres to **Rule 15 compliance**:
#### β
Zero Suppressions Policy
```go
// β
GOOD: Proper error handling in tests
func TestTaskCreation(t *testing.T) {
task, err := createTask("Test Task")
require.NoError(t, err) // Explicit error checking
assert.NotEmpty(t, task.ID)
}
// β BAD: Suppressing test failures
func TestTaskCreationBad(t *testing.T) {
task, _ := createTask("Test Task") // Ignoring error
// @ts-ignore missing assertion
}
```
#### ποΈ DRY Test Patterns
```go
// β
GOOD: Reusable test helpers
func setupTestEnvironment(t *testing.T) (*TestEnv, func()) {
// Single setup pattern used across all tests
env := &TestEnv{
Database: setupTestDB(t),
Server: setupTestServer(t),
}
cleanup := func() {
env.Database.Close()
env.Server.Close()
}
return env, cleanup
}
// Usage across multiple test files
func TestUserOperations(t *testing.T) {
env, cleanup := setupTestEnvironment(t)
defer cleanup()
// Test implementation...
}
```
#### π§ Comprehensive Resource Cleanup
```go
func TestDatabaseOperations(t *testing.T) {
db, cleanup := testinghelpers.SetupTestDatabase(t)
defer cleanup() // Always cleanup resources
// Test operations...
// Verify cleanup in test
t.Cleanup(func() {
assert.Empty(t, db.ActiveConnections())
})
}
```

## π¬ Testing Methodologies
### 1. **Table-Driven Tests**
**Philosophy**: Systematic test case organization with comprehensive coverage
```go
func TestTaskValidation(t *testing.T) {
tests := []struct {
name string
task *Task
expectError bool
errorType error
}{
{
name: "Valid task",
task: &Task{
Title: "Valid Task",
Priority: "high",
Status: "pending",
},
expectError: false,
},
{
name: "Missing title",
task: &Task{
Title: "",
Priority: "high",
Status: "pending",
},
expectError: true,
errorType: ErrMissingTitle,
},
{
name: "Invalid priority",
task: &Task{
Title: "Test Task",
Priority: "invalid",
Status: "pending",
},
expectError: true,
errorType: ErrInvalidPriority,
},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
err := ValidateTask(tt.task)
if tt.expectError {
assert.Error(t, err)
assert.ErrorIs(t, err, tt.errorType)
} else {
assert.NoError(t, err)
}
})
}
}
```
### 2. **Race Condition Testing**
**Philosophy**: Ensure thread safety under concurrent load
```go
func TestConcurrentTaskOperations(t *testing.T) {
taskManager := NewTaskManager()
const numGoroutines = 50
const operationsPerGoroutine = 100
var wg sync.WaitGroup
errors := make(chan error, numGoroutines)
// Concurrent task creation
for i := 0; i < numGoroutines; i++ {
wg.Add(1)
go func(workerID int) {
defer wg.Done()
for j := 0; j < operationsPerGoroutine; j++ {
taskTitle := fmt.Sprintf("Task-%d-%d", workerID, j)
_, err := taskManager.CreateTask(taskTitle)
if err != nil {
errors <- err
return
}
}
}(i)
}
wg.Wait()
close(errors)
// Check for any errors
for err := range errors {
t.Errorf("Concurrent operation failed: %v", err)
}
// Verify expected number of tasks created
totalTasks := numGoroutines * operationsPerGoroutine
actualCount, err := taskManager.GetTaskCount()
require.NoError(t, err)
assert.Equal(t, totalTasks, actualCount)
}
```
### 3. **Resource Cleanup Testing**
**Philosophy**: Ensure proper resource management following Rule 15
```go
func TestResourceCleanup(t *testing.T) {
// Setup resource tracking
initialFDs := getOpenFileDescriptors()
initialConnections := getDatabaseConnections()
t.Run("File operations cleanup", func(t *testing.T) {
fileManager := NewFileManager()
// Perform multiple file operations
for i := 0; i < 10; i++ {
file, err := fileManager.OpenFile(fmt.Sprintf("test%d.txt", i))
require.NoError(t, err)
// Write and read operations
_, err = file.Write([]byte("test data"))
require.NoError(t, err)
// Explicit cleanup
err = fileManager.CloseFile(file)
require.NoError(t, err)
}
// Verify no resource leaks
currentFDs := getOpenFileDescriptors()
assert.Equal(t, initialFDs, currentFDs, "File descriptor leak detected")
})
t.Run("Database operations cleanup", func(t *testing.T) {
dbManager := NewDatabaseManager()
// Perform database operations
for i := 0; i < 5; i++ {
conn, err := dbManager.GetConnection()
require.NoError(t, err)
// Database operations
_, err = conn.Query("SELECT 1")
require.NoError(t, err)
// Return connection to pool
err = dbManager.ReturnConnection(conn)
require.NoError(t, err)
}
// Verify no connection leaks
currentConnections := getDatabaseConnections()
assert.Equal(t, initialConnections, currentConnections, "Database connection leak detected")
})
}
```
### 4. **Error Boundary Testing**
**Philosophy**: Validate system behavior under error conditions
```go
func TestErrorBoundaries(t *testing.T) {
testCases := []struct {
name string
errorScenario func() error
expectedBehavior string
}{
{
name: "Database connection failure",
errorScenario: func() error {
// Simulate database failure
return simulateDatabaseFailure()
},
expectedBehavior: "graceful_degradation",
},
{
name: "Memory exhaustion",
errorScenario: func() error {
// Simulate memory pressure
return simulateMemoryPressure()
},
expectedBehavior: "resource_limiting",
},
{
name: "Network timeout",
errorScenario: func() error {
// Simulate network timeout
return simulateNetworkTimeout()
},
expectedBehavior: "retry_with_backoff",
},
}
for _, tc := range testCases {
t.Run(tc.name, func(t *testing.T) {
err := tc.errorScenario()
// Verify error handling behavior
switch tc.expectedBehavior {
case "graceful_degradation":
assert.Error(t, err)
assert.True(t, IsRecoverableError(err))
case "resource_limiting":
assert.Error(t, err)
assert.True(t, IsResourceError(err))
case "retry_with_backoff":
assert.Error(t, err)
assert.True(t, IsRetryableError(err))
}
})
}
}
```

### π Load Testing
#### Concurrent User Simulation
```go
func TestHighLoadScenario(t *testing.T) {
if testing.Short() {
t.Skip("Skipping load test in short mode")
}
const (
numUsers = 100
operationsPerUser = 50
testDuration = 30 * time.Second
)
manager := NewTaskManager()
ctx, cancel := context.WithTimeout(context.Background(), testDuration)
defer cancel()
var wg sync.WaitGroup
results := make(chan TestResult, numUsers)
// Simulate concurrent users
for userID := 0; userID < numUsers; userID++ {
wg.Add(1)
go func(id int) {
defer wg.Done()
userResult := TestResult{UserID: id}
startTime := time.Now()
for op := 0; op < operationsPerUser && ctx.Err() == nil; op++ {
// Mix of operations
switch op % 4 {
case 0: // Create task
_, err := manager.CreateTask(fmt.Sprintf("User%d-Task%d", id, op))
if err != nil {
userResult.Errors++
} else {
userResult.SuccessfulOps++
}
case 1: // List tasks

if err != nil {
userResult.Errors++
} else {
userResult.SuccessfulOps++
}
case 2: // Update task (if exists)
tasks, _ := manager.GetUserTasks(id)
if len(tasks) > 0 {
err := manager.UpdateTask(tasks[0].ID, map[string]interface{}{
"status": "completed",
})
if err != nil {
userResult.Errors++
} else {
userResult.SuccessfulOps++
}
}
case 3: // Search tasks

if err != nil {
userResult.Errors++
} else {
userResult.SuccessfulOps++
}
}
}
userResult.Duration = time.Since(startTime)
results <- userResult
}(userID)
}
wg.Wait()
close(results)
// Analyze results
var totalOps, totalErrors int
var totalDuration time.Duration
for result := range results {
totalOps += result.SuccessfulOps
totalErrors += result.Errors
totalDuration += result.Duration
}
avgDuration := totalDuration / time.Duration(numUsers)

}
```

## π Best Practices
### β
Test Writing Guidelines
#### 1. **Descriptive Test Names**
```go
// β
GOOD: Descriptive and specific
func TestNLPProcessor_ShouldReturnHighConfidenceForExplicitTaskCreationQuery(t *testing.T) {
// Test implementation...
}
func TestTaskManager_ShouldThrowValidationErrorWhenTitleIsEmpty(t *testing.T) {
// Test implementation...
}
// β BAD: Vague and generic
func TestNLP(t *testing.T) {
// Test implementation...
}
func TestValidation(t *testing.T) {
// Test implementation...
}
```
#### 2. **Comprehensive Error Testing**
```go
// β
GOOD: Test both success and failure cases
func TestTaskCreation(t *testing.T) {
manager := NewTaskManager()
t.Run("successful creation", func(t *testing.T) {
task, err := manager.CreateTask("Valid Task")
assert.NoError(t, err)
assert.NotEmpty(t, task.ID)
assert.Equal(t, "Valid Task", task.Title)
})
t.Run("empty title should fail", func(t *testing.T) {
_, err := manager.CreateTask("")
assert.Error(t, err)
assert.Contains(t, err.Error(), "title cannot be empty")
})
t.Run("duplicate title should fail", func(t *testing.T) {
_, err := manager.CreateTask("Valid Task") // Already created above
assert.Error(t, err)
assert.ErrorIs(t, err, ErrDuplicateTitle)
})
}
```
#### 3. **Resource Management in Tests**
```go
// β
GOOD: Proper resource cleanup
func TestDatabaseOperations(t *testing.T) {
db, cleanup := setupTestDatabase(t)
defer cleanup() // Always cleanup
// Additional cleanup verification
t.Cleanup(func() {
connections := db.Stats().OpenConnections
assert.Zero(t, connections, "All connections should be closed")
})
// Test implementation...
}
```
#### 4. **Mock and Stub Usage**
```go
// β
GOOD: Use mocks for external dependencies
func TestTaskManager_WithExternalAPI(t *testing.T) {
mockClient := &MockAPIClient{}
mockClient.On("GetUserInfo", "user123").Return(&UserInfo{
ID: "user123",
Name: "Test User",
}, nil)
manager := NewTaskManager()
manager.SetAPIClient(mockClient)
task, err := manager.CreateTaskForUser("user123", "Test Task")
require.NoError(t, err)
assert.Equal(t, "user123", task.AssignedTo)
mockClient.AssertExpectations(t)
}
```
### π§ Test Organization
#### 1. **Test File Structure**
```
internal/gorev/
βββ task_manager.go
βββ task_manager_test.go # Core functionality tests
βββ task_manager_integration_test.go # Integration tests
βββ task_manager_benchmark_test.go # Performance tests
```
#### 2. **Test Helper Functions**
```go
// helpers_test.go
func setupTestEnvironment(t *testing.T) (*TestEnvironment, func()) {
db := setupTestDatabase(t)
server := setupTestServer(t)
client := setupTestClient(t)
env := &TestEnvironment{
Database: db,
Server: server,
Client: client,
}
cleanup := func() {
client.Close()
server.Close()
db.Close()
}
return env, cleanup
}
func createTestTask(t *testing.T, manager *TaskManager, title string) *Task {
task, err := manager.CreateTask(title)
require.NoError(t, err)
return task
}
```
### π Test Data Management
#### 1. **Fixtures and Test Data**
```go
// fixtures/tasks.go
var TestTasks = []*Task{
{
ID: "task-001",
Title: "Sample Bug Fix",
Priority: "high",
Status: "pending",
Tags: []string{"bug", "urgent"},
},
{
ID: "task-002",
Title: "Feature Implementation",
Priority: "medium",
Status: "in_progress",
Tags: []string{"feature", "api"},
},
}
func LoadTestTasks() []*Task {
// Deep copy to avoid test interference
tasks := make([]*Task, len(TestTasks))
for i, task := range TestTasks {
taskCopy := *task
tasks[i] = &taskCopy
}
return tasks
}
```
#### 2. **Database Seeding**
```go
func seedTestDatabase(t *testing.T, db *Database) {
tasks := fixtures.LoadTestTasks()
for _, task := range tasks {
err := db.CreateTask(task)
require.NoError(t, err, "Failed to seed task: %s", task.Title)
}
projects := fixtures.LoadTestProjects()
for _, project := range projects {
err := db.CreateProject(project)
require.NoError(t, err, "Failed to seed project: %s", project.Name)
}
}
```

## π Troubleshooting
### π¨ Common Testing Issues
#### 1. **Test Isolation Problems**
**Problem**: Tests interfere with each other
**Symptoms**:
```
Test A passes when run alone
Test A fails when run with Test B
Random test failures in CI/CD
```
**Solutions**:
```go
// β
SOLUTION: Proper test isolation
func TestTaskOperations(t *testing.T) {
// Each test gets its own database
t.Run("create task", func(t *testing.T) {
db, cleanup := setupTestDatabase(t)
defer cleanup()
manager := NewTaskManager(db)
// Test implementation...
})
t.Run("update task", func(t *testing.T) {
db, cleanup := setupTestDatabase(t)
defer cleanup()
manager := NewTaskManager(db)
// Test implementation...
})
}
```
#### 2. **Race Condition in Tests**
**Problem**: Tests fail intermittently due to race conditions
**Symptoms**:
```
go test -race -count=10 ./...
WARNING: DATA RACE
Read at 0x... by goroutine 2:
Write at 0x... by goroutine 1:
```
**Solutions**:
```go
// β
SOLUTION: Proper synchronization
func TestConcurrentOperations(t *testing.T) {
manager := NewTaskManager()
const numGoroutines = 10
var wg sync.WaitGroup
// Use channels for synchronization
results := make(chan string, numGoroutines)
for i := 0; i < numGoroutines; i++ {
wg.Add(1)
go func(id int) {
defer wg.Done()
task, err := manager.CreateTask(fmt.Sprintf("Task %d", id))
if err != nil {
t.Errorf("Failed to create task: %v", err)
return
}
results <- task.ID
}(i)
}
wg.Wait()
close(results)
// Verify results
taskIDs := make([]string, 0, numGoroutines)
for taskID := range results {
taskIDs = append(taskIDs, taskID)
}
assert.Len(t, taskIDs, numGoroutines)
}
```
#### 3. **Resource Leak in Tests**
**Problem**: Tests cause resource leaks affecting subsequent tests
**Symptoms**:
```
Too many open files
Database connection pool exhausted
Memory usage continuously increasing
```
**Solutions**:
```go
// β
SOLUTION: Comprehensive cleanup
func TestWithResourceCleanup(t *testing.T) {
// Track resource usage before test
initialFDs := getOpenFileDescriptors()
initialConnections := getActiveConnections()
// Setup test resources with explicit cleanup
resources, cleanup := setupResources(t)
defer func() {
cleanup()
// Verify resource cleanup
currentFDs := getOpenFileDescriptors()
currentConnections := getActiveConnections()
assert.Equal(t, initialFDs, currentFDs, "File descriptor leak")
assert.Equal(t, initialConnections, currentConnections, "Connection leak")
}()
// Test implementation using resources...
}
```
#### 4. **Flaky Test Debugging**
**Problem**: Tests pass/fail inconsistently
**Diagnosis Commands**:
```bash
# Run tests multiple times to identify flaky tests
go test -count=100 -failfast ./internal/gorev/
# Run with race detection
go test -race -count=10 ./...
# Run with verbose output
go test -v -count=5 ./...
# Run specific test multiple times
go test -run TestSpecificFunction -count=20
```
**Common Fixes**:
```go
// β
FIX: Add proper timeouts
func TestAsyncOperation(t *testing.T) {
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
result := make(chan string, 1)
go func() {
// Async operation
result <- performOperation()
}()
select {
case res := <-result:
assert.NotEmpty(t, res)
case <-ctx.Done():
t.Fatal("Operation timed out")
}
}
// β
FIX: Deterministic ordering
func TestOrderedOperations(t *testing.T) {
manager := NewTaskManager()
// Create tasks in specific order
task1, _ := manager.CreateTask("Task 1")
task2, _ := manager.CreateTask("Task 2")
task3, _ := manager.CreateTask("Task 3")
// Wait for all operations to complete
time.Sleep(10 * time.Millisecond)
// Verify order is maintained
tasks, _ := manager.GetTasks()
assert.Equal(t, []string{task1.ID, task2.ID, task3.ID}, getTaskIDs(tasks))
}
```
### π Test Performance Issues
#### Slow Test Identification
```bash
# Identify slow tests
go test -v ./... | grep -E "PASS|FAIL" | sort -k2 -nr
# Profile test execution
go test -cpuprofile cpu.prof -memprofile mem.prof ./...
# Analyze profiles
go tool pprof cpu.prof
go tool pprof mem.prof
```
#### Test Optimization
```go
// β
OPTIMIZED: Parallel test execution
func TestParallelOperations(t *testing.T) {
if testing.Short() {
t.Skip("Skipping in short mode")
}
tests := []struct {
name string
fn func(t *testing.T)
}{
{"test1", testFunction1},
{"test2", testFunction2},
{"test3", testFunction3},
}
for _, tt := range tests {
tt := tt // Capture range variable
t.Run(tt.name, func(t *testing.T) {
t.Parallel() // Run in parallel
tt.fn(t)
})
}
}
// β
OPTIMIZED: Shared setup for related tests
func TestSuiteWithSharedSetup(t *testing.T) {
// Expensive setup once
db, cleanup := setupLargeTestDatabase(t)
defer cleanup()
// Multiple tests using same setup
t.Run("test1", func(t *testing.T) {
// Use db...
})
t.Run("test2", func(t *testing.T) {
// Use db...
})
}
```
