#[tokio::test]
async fn test_project_lifecycle() {

    // 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]

    // Real implementation would test:
    // 1. Register agent
    // 2. List agents
    // 3. Update agent status
    // 4. Check agent health
    // 5. Deregister agent

#[tokio::test]

    // Real implementation would test:
    // 1. Create multiple tasks in different columns
    // 2. Move task between columns
    // 3. Reorder tasks within a column
    // 4. Verify task order is maintained
}

#[tokio::test]
async fn test_error_handling() {

    // 2. Invalid input errors (400)
    // 3. Unauthorized errors (401)
    // 4. Database errors (500)

// Note: To run these tests properly, you would need:
// 1. A test SurrealDB instance running
// 2. Test fixtures and cleanup
// 3. TestServer setup from axum_test
//
// Example of a real test structure:
//
// #[tokio::test]
// async fn test_create_project_real() {
//     let app = build_test_app().await;
//     let server = TestServer::new(app).unwrap();
//
//     let project = create_test_project();
//     let response = server
//         .post("/api/v1/projects")
//         .json(&project)
//         .await;
//
//     assert_eq!(response.status_code(), StatusCode::CREATED);
//     let created: Project = response.json();
//     assert_eq!(created.title, project.title);
