# 🧪 **apt-ostree Testing Strategy**
## 🎯 **Overview**
This document outlines the comprehensive testing strategy for apt-ostree, covering unit testing, integration testing, system testing, and CI/CD integration. The testing approach ensures reliability, compatibility with rpm-ostree, and production readiness.
## 🏗️ **Testing Architecture**
### **Testing Pyramid**
```
/\
/ \ E2E Tests (Few, Slow)
/____\
/ \ Integration Tests (Some, Medium)
/________\
/ \ Unit Tests (Many, Fast)
/____________\
```
### **Test Categories**
- **Unit Tests** - Individual component testing
- **Integration Tests** - Component interaction testing
- **System Tests** - End-to-end system testing
- **Performance Tests** - Performance and scalability testing
- **Security Tests** - Security and authorization testing
## 🔧 **Unit Testing Strategy**
### **Core Components to Test**
#### **CLI Commands**
```rust
// src/commands/status.rs
#[cfg(test)]
mod tests {
use super::*;
use crate::test_utils::*;
#[tokio::test]
async fn test_status_command_basic() {
let mut cmd = StatusCommand::new();
let args = vec!["status".to_string()];
let result = cmd.execute(&args).await;
assert!(result.is_ok());
}
#[tokio::test]
async fn test_status_command_with_os() {
let mut cmd = StatusCommand::new();
let args = vec!["status".to_string(), "--os".to_string(), "debian".to_string()];
let result = cmd.execute(&args).await;
assert!(result.is_ok());
}
#[tokio::test]
async fn test_status_command_json_output() {
let mut cmd = StatusCommand::new();
let args = vec!["status".to_string(), "--json".to_string()];
let result = cmd.execute(&args).await;
assert!(result.is_ok());
}
}
```
#### **Package Management**
```rust
// src/package/package_manager.rs
#[cfg(test)]
mod tests {
use super::*;
use crate::test_utils::*;
#[test]
fn test_package_info_parsing() {
let dpkg_output = "Package: vim\nVersion: 2:9.0.1378-1\nDepends: libc6";
let package_info = parse_dpkg_output(dpkg_output).unwrap();
assert_eq!(package_info.name, "vim");
assert_eq!(package_info.version, "2:9.0.1378-1");
assert!(package_info.depends.contains(&"libc6".to_string()));
}
#[test]
fn test_dependency_resolution() {
let mut manager = PackageManager::new();
let deps = vec!["vim".to_string(), "emacs".to_string()];
let resolved = manager.resolve_dependencies(&deps).unwrap();
assert!(!resolved.is_empty());
}
}
```
#### **OSTree Integration**
```rust
// src/ostree/ostree_manager.rs
#[cfg(test)]
mod tests {
use super::*;
use crate::test_utils::*;
#[tokio::test]
async fn test_deployment_listing() {
let manager = OstreeManager::new();
let deployments = manager.list_deployments().await.unwrap();
assert!(!deployments.is_empty());
}
#[tokio::test]
async fn test_system_info_gathering() {
let manager = OstreeManager::new();
let info = manager.get_system_info().await.unwrap();
assert!(!info.os.is_empty());
assert!(!info.kernel.is_empty());
assert!(!info.architecture.is_empty());
}
}
```
### **Test Utilities and Mocking**
#### **Test Utilities**
```rust
// src/test_utils/mod.rs
use std::path::PathBuf;
use tempfile::TempDir;
pub struct TestEnvironment {
pub temp_dir: TempDir,
pub ostree_repo: PathBuf,
pub apt_cache: PathBuf,
}
impl TestEnvironment {
pub fn new() -> Result<Self, Box<dyn std::error::Error>> {
let temp_dir = tempfile::tempdir()?;
let ostree_repo = temp_dir.path().join("ostree");
let apt_cache = temp_dir.path().join("apt");
// Initialize test environment
std::fs::create_dir_all(&ostree_repo)?;
std::fs::create_dir_all(&apt_cache)?;
Ok(Self {
temp_dir,
ostree_repo,
apt_cache,
})
}
pub fn create_mock_package(&self, name: &str, version: &str) -> Result<(), Box<dyn std::error::Error>> {
let package_dir = self.apt_cache.join(format!("{}_{}", name, version));
std::fs::create_dir_all(&package_dir)?;
// Create mock package files
std::fs::write(package_dir.join("control"), format!("Package: {}\nVersion: {}", name, version))?;
Ok(())
}
}
impl Drop for TestEnvironment {
fn drop(&mut self) {
// Cleanup happens automatically with TempDir
}
}
```
#### **Mock Services**
```rust
// src/test_utils/mock_services.rs
use async_trait::async_trait;
use crate::daemon::DaemonService;
pub struct MockDaemonService {
pub should_fail: bool,
pub mock_responses: std::collections::HashMap<String, String>,
}
#[async_trait]
impl DaemonService for MockDaemonService {
async fn handle_request(&self, request: &str) -> Result<String, Box<dyn std::error::Error>> {
if self.should_fail {
return Err("Mock failure".into());
}
if let Some(response) = self.mock_responses.get(request) {
Ok(response.clone())
} else {
Ok("Mock response".to_string())
}
}
}
```

let daemon = AptOstreeDaemon::start().await.unwrap();
// Create client
let client = AptOstreeClient::new().await.unwrap();
// Test communication
let status = client.get_system_status().await.unwrap();
assert!(!status.deployments.is_empty());
// Cleanup
daemon.stop().await.unwrap();
}
```
#### **Package Installation Flow**

// Create mock package
env.create_mock_package("vim", "2:9.0.1378-1").unwrap();
// Test installation
let mut cmd = InstallCommand::new();
let args = vec!["install".to_string(), "vim".to_string()];
let result = cmd.execute(&args).await;
assert!(result.is_ok());
// Verify installation
let status = cmd.get_installation_status().await.unwrap();
assert!(status.installed_packages.contains(&"vim".to_string()));
}
```
### **Database Integration Testing**
#### **APT Database Operations**
```rust

use apt_ostree::package::apt_manager::AptManager;
#[tokio::test]
async fn test_apt_database_operations() {
let manager = AptManager::new();
// Test package listing
let packages = manager.list_available_packages().await.unwrap();
assert!(!packages.is_empty());
// Test package search
let search_results = manager.search_packages("vim").await.unwrap();
assert!(!search_results.is_empty());
// Test dependency resolution
let deps = manager.resolve_dependencies(&vec!["vim".to_string()]).await.unwrap();
assert!(!deps.is_empty());
}
```

### **End-to-End Testing**
#### **Complete System Operations**
```rust
// tests/system/complete_operations.rs
use apt_ostree::test_utils::SystemTestEnvironment;
#[tokio::test]
async fn test_complete_system_upgrade() {
let env = SystemTestEnvironment::new().await.unwrap();
// Initial state
let initial_status = env.run_command("apt-ostree status").await.unwrap();
let initial_version = extract_version(&initial_status);
// Perform upgrade
let upgrade_result = env.run_command("apt-ostree upgrade").await.unwrap();
assert!(upgrade_result.success);
// Verify upgrade
let final_status = env.run_command("apt-ostree status").await.unwrap();
let final_version = extract_version(&final_status);
assert_ne!(initial_version, final_version);
}
```
#### **Package Management Workflows**
```rust
// tests/system/package_management.rs
use apt_ostree::test_utils::SystemTestEnvironment;
#[tokio::test]
async fn test_package_install_uninstall_workflow() {
let env = SystemTestEnvironment::new().await.unwrap();
// Install package
let install_result = env.run_command("apt-ostree install vim").await.unwrap();
assert!(install_result.success);
// Verify installation
let status = env.run_command("apt-ostree status").await.unwrap();
assert!(status.output.contains("vim"));
// Uninstall package
let uninstall_result = env.run_command("apt-ostree uninstall vim").await.unwrap();
assert!(uninstall_result.success);
// Verify uninstallation
let final_status = env.run_command("apt-ostree status").await.unwrap();
assert!(!final_status.output.contains("vim"));
}
```
### **Performance Testing**
#### **Load Testing**
```rust
// tests/performance/load_testing.rs
use tokio::time::{Duration, Instant};
use std::sync::Arc;
use tokio::sync::Semaphore;
#[tokio::test]
async fn test_concurrent_package_operations() {
let semaphore = Arc::new(Semaphore::new(10)); // Limit concurrent operations
let start_time = Instant::now();
let mut handles = vec![];
for i in 0..100 {
let permit = semaphore.clone().acquire_owned().await.unwrap();
let handle = tokio::spawn(async move {
// Simulate package operation
tokio::time::sleep(Duration::from_millis(10)).await;
drop(permit);
});
handles.push(handle);
}
// Wait for all operations to complete
for handle in handles {
handle.await.unwrap();
}
let duration = start_time.elapsed();
assert!(duration < Duration::from_secs(5)); // Should complete within 5 seconds
}
```
#### **Memory Usage Testing**
```rust
// tests/performance/memory_testing.rs
use std::alloc::{GlobalAlloc, Layout};
use std::sync::atomic::{AtomicUsize, Ordering};
static ALLOCATED: AtomicUsize = AtomicUsize::new(0);
struct TestAllocator;
unsafe impl GlobalAlloc for TestAllocator {
unsafe fn alloc(&self, layout: Layout) -> *mut u8 {
ALLOCATED.fetch_add(layout.size(), Ordering::SeqCst);
std::alloc::System.alloc(layout)
}
unsafe fn dealloc(&self, ptr: *mut u8, layout: Layout) {
ALLOCATED.fetch_sub(layout.size(), Ordering::SeqCst);
std::alloc::System.dealloc(ptr, layout);
}
}
#[global_allocator]
static GLOBAL: TestAllocator = TestAllocator;
#[test]
fn test_memory_usage() {
let initial_memory = ALLOCATED.load(Ordering::SeqCst);
// Perform operations that allocate memory
let _large_vec: Vec<u8> = vec![0; 1024 * 1024]; // 1MB
let peak_memory = ALLOCATED.load(Ordering::SeqCst);
let memory_increase = peak_memory - initial_memory;
// Verify memory is properly managed
assert!(memory_increase >= 1024 * 1024); // Should allocate at least 1MB
// Memory should be freed after this scope
drop(_large_vec);
let final_memory = ALLOCATED.load(Ordering::SeqCst);
assert_eq!(final_memory, initial_memory); // Memory should be freed
}
```
## 🔒 **Security Testing Strategy**
### **Authorization Testing**

let manager = PolkitManager::new();
// Test authorized user
let authorized_user = 1000; // Regular user
let result = manager.check_authorization("org.projectatomic.aptostree.status", authorized_user).await;
assert!(result.is_ok());
// Test unauthorized action
let result = manager.check_authorization("org.projectatomic.aptostree.upgrade", authorized_user).await;
assert!(result.is_err()); // Should fail for regular user
}
#[tokio::test]
async fn test_polkit_policy_validation() {
let manager = PolkitManager::new();
// Test valid policy
let valid_policy = "org.projectatomic.aptostree.status";
let result = manager.validate_policy(valid_policy).await;
assert!(result.is_ok());
// Test invalid policy
let invalid_policy = "org.projectatomic.aptostree.invalid";
let result = manager.validate_policy(invalid_policy).await;
assert!(result.is_err());
}
```
#### **Privilege Escalation Testing**
```rust
// tests/security/privilege_escalation.rs
use apt_ostree::security::privilege_manager::PrivilegeManager;
#[tokio::test]
async fn test_privilege_escalation_prevention() {
let manager = PrivilegeManager::new();
// Test that regular users cannot escalate privileges
let regular_user = 1000;
let result = manager.check_privilege_escalation(regular_user, "root").await;
assert!(result.is_err()); // Should fail
// Test that privileged operations require proper authorization
let result = manager.check_privilege_escalation(regular_user, "sudo").await;
assert!(result.is_err()); // Should fail
}
```
