    // For now, it's a placeholder demonstrating the test structure
    // Real implementation would:
    // 1. Create a TestServer with the app
    // 2. POST /api/v1/projects - create project
    // 3. GET /api/v1/projects/:id - verify creation
    // 4. PUT /api/v1/projects/:id - update project
    // 5. DELETE /api/v1/projects/:id - delete project
}

#[tokio::test]
async fn test_task_lifecycle() {
    // Note: Placeholder test
    // Real implementation would test:
    // 1. Create task
    // 2. List tasks
    // 3. Update task status
    // 4. Reorder task
    // 5. Delete task
}

#[tokio::test]

    // 4. Verify task order is maintained
