+# 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
+```bash
+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
+
+1. **`framework.go`** - Test infrastructure and utilities
+   - `FuseTestFramework` - Main test management struct
+   - Automated SeaweedFS cluster setup/teardown
+   - FUSE mount/unmount management
+   - Helper functions for file operations and assertions
+
+2. **`basic_operations_test.go`** - Fundamental FUSE operations
+   - File create, read, write, delete
+   - File attributes and permissions
+   - Large file handling
+   - Sparse file operations
+
+3. **`directory_operations_test.go`** - Directory-specific tests
+   - Directory creation, deletion, listing
+   - Nested directory structures
+   - Directory permissions and rename operations
+   - Complex directory scenarios
+
+4. **`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
+```go
+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
+```go
+config := &TestConfig{
+    Collection:   "test",
+    Replication:  "001", 
+    ChunkSizeMB:  8,
+    CacheSizeMB:  200,
+    NumVolumes:   5,
+    EnableDebug:  true,
+    MountOptions: []string{"-allowOthers"},
+}
+```
+
+### Rich Assertion Helpers
+```go
+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
+```bash
+# 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
+```go
+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
+```go
+config := &TestConfig{
+    EnableDebug:  true,     // Enable verbose logging
+    SkipCleanup:  true,     // Keep temp files for inspection
+}
+```
+
+## Advanced Features
+
+### Performance Benchmarking
+```go
+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
+```go
+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)
+}
+```
+
+## Integration with CI/CD
+
+### GitHub Actions Example
+```yaml
+name: FUSE Integration Tests
+on: [push, pull_request]
+
+jobs:
+  fuse-tests:
+    runs-on: ubuntu-latest
+    steps:
+    - uses: actions/checkout@v3
+    - uses: actions/setup-go@v3
+      with:
+        go-version: '1.21'
+    
+    - name: Install FUSE
+      run: sudo apt-get install -y fuse
+    
+    - name: Build SeaweedFS
+      run: make
+    
+    - name: Run FUSE Tests
+      run: |
+        cd test/fuse_integration
+        go test -v -timeout 30m
+```
+
+### Docker Testing
+```dockerfile
+FROM golang:1.21
+RUN apt-get update && apt-get install -y fuse
+COPY . /seaweedfs
+WORKDIR /seaweedfs
+RUN make
+CMD ["go", "test", "-v", "./test/fuse_integration/..."]
+```
+
+## Comparison with Current Testing

+// - Simulates FUSE operations using local filesystem (not actual FUSE mounts)
+// - Validates the testing approach and framework design

+//
+// DUPLICATION RATIONALE:
+// - The full framework (framework.go) has Go module conflicts with parent project
+// - This standalone version proves the concept works without those conflicts
+// - Once module issues are resolved, this can be removed or simplified
+//
+// TODO: Remove this file once framework.go module conflicts are resolved
