SeaweedFS FUSE Integration Testing Framework
Overview
This directory contains a comprehensive integration testing framework for SeaweedFS FUSE operations. The current SeaweedFS FUSE tests are primarily performance-focused (using FIO) but lack comprehensive functional testing. This framework addresses those gaps.
⚠️ Current Status
Note: Due to Go module conflicts between this test framework and the parent SeaweedFS module, the full test suite currently requires manual setup. The framework files are provided as a foundation for comprehensive FUSE testing once the module structure is resolved.
Working Components
- ✅ Framework design and architecture (
framework.go
) - ✅ Individual test file structure and compilation
- ✅ Test methodology and comprehensive coverage
- ✅ Documentation and usage examples
- ⚠️ Full test suite execution (requires Go module isolation)
Verified Working Test
cd test/fuse_integration
go test -v simple_test.go
Current Testing Gaps Addressed
1. Limited Functional Coverage
- Current: Only basic FIO performance tests
- New: Comprehensive testing of all FUSE operations (create, read, write, delete, mkdir, rmdir, permissions, etc.)
2. No Concurrency Testing
- Current: Single-threaded performance tests
- New: Extensive concurrent operation tests, race condition detection, thread safety validation
3. Insufficient Error Handling
- Current: Basic error scenarios
- New: Comprehensive error condition testing, edge cases, failure recovery
4. Missing Edge Cases
- Current: Simple file operations
- New: Large files, sparse files, deep directory nesting, many small files, permission variations
Framework Architecture
Core Components
-
framework.go
- Test infrastructure and utilitiesFuseTestFramework
- Main test management struct- Automated SeaweedFS cluster setup/teardown
- FUSE mount/unmount management
- Helper functions for file operations and assertions
-
basic_operations_test.go
- Fundamental FUSE operations- File create, read, write, delete
- File attributes and permissions
- Large file handling
- Sparse file operations
-
directory_operations_test.go
- Directory-specific tests- Directory creation, deletion, listing
- Nested directory structures
- Directory permissions and rename operations
- Complex directory scenarios
-
concurrent_operations_test.go
- Concurrency and stress testing- Concurrent file and directory operations
- Race condition detection
- High-frequency operations
- Stress testing scenarios
Key Features
Automated Test Environment
framework := NewFuseTestFramework(t, DefaultTestConfig())
defer framework.Cleanup()
require.NoError(t, framework.Setup(DefaultTestConfig()))
- Automatic cluster setup: Master, Volume, Filer servers
- FUSE mounting: Proper mount point management
- Cleanup: Automatic teardown of all resources
Configurable Test Parameters
config := &TestConfig{
Collection: "test",
Replication: "001",
ChunkSizeMB: 8,
CacheSizeMB: 200,
NumVolumes: 5,
EnableDebug: true,
MountOptions: []string{"-allowOthers"},
}
Rich Assertion Helpers
framework.AssertFileExists("path/to/file")
framework.AssertFileContent("file.txt", expectedContent)
framework.AssertFileMode("script.sh", 0755)
framework.CreateTestFile("test.txt", []byte("content"))
Test Categories
1. Basic File Operations
- Create/Read/Write/Delete: Fundamental file operations
- File Attributes: Size, timestamps, permissions
- Append Operations: File appending behavior
- Large Files: Files exceeding chunk size limits
- Sparse Files: Non-contiguous file data
2. Directory Operations
- Directory Lifecycle: Create, list, remove directories
- Nested Structures: Deep directory hierarchies
- Directory Permissions: Access control testing
- Directory Rename: Move operations
- Complex Scenarios: Many files, deep nesting
3. Concurrent Operations
- Multi-threaded Access: Simultaneous file operations
- Race Condition Detection: Concurrent read/write scenarios
- Directory Concurrency: Parallel directory operations
- Stress Testing: High-frequency operations
4. Error Handling & Edge Cases
- Permission Denied: Access control violations
- Disk Full: Storage limit scenarios
- Network Issues: Filer/Volume server failures
- Invalid Operations: Malformed requests
- Recovery Testing: Error recovery scenarios
Usage Examples
Basic Test Run
# Build SeaweedFS binary
make
# Run all FUSE tests
cd test/fuse_integration
go test -v
# Run specific test category
go test -v -run TestBasicFileOperations
go test -v -run TestConcurrentFileOperations
Custom Configuration
func TestCustomFUSE(t *testing.T) {
config := &TestConfig{
ChunkSizeMB: 16, // Larger chunks
CacheSizeMB: 500, // More cache
EnableDebug: true, // Debug output
SkipCleanup: true, // Keep files for inspection
}
framework := NewFuseTestFramework(t, config)
defer framework.Cleanup()
require.NoError(t, framework.Setup(config))
// Your tests here...
}
Debugging Failed Tests
config := &TestConfig{
EnableDebug: true, // Enable verbose logging
SkipCleanup: true, // Keep temp files for inspection
}
Advanced Features
Performance Benchmarking
func BenchmarkLargeFileWrite(b *testing.B) {
framework := NewFuseTestFramework(t, DefaultTestConfig())
defer framework.Cleanup()
require.NoError(t, framework.Setup(DefaultTestConfig()))
b.ResetTimer()
for i := 0; i < b.N; i++ {
// Benchmark file operations
}
}
Custom Test Scenarios
func TestCustomWorkload(t *testing.T) {
framework := NewFuseTestFramework(t, DefaultTestConfig())
defer framework.Cleanup()
require.NoError(t, framework.Setup(DefaultTestConfig()))
// Simulate specific application workload
simulateWebServerWorkload(t, framework)
simulateDatabaseWorkload(t, framework)
simulateBackupWorkload(t, framework)
}
