promisify automock socketio

This code defines a function promisifyMock that creates mock implementations for asynchronous functions in a request object, enabling easier testing by replacing these functions with controlled stubs.

This code creates a Socket.IO server that uses a custom mocking system to replace dependencies with event-based communication, allowing for real-time data sharing between clients.

sockifyClient creates a mock Socket.IO client that intercepts function calls on a dependency object and emits events to a server, enabling testing of Socket.IO interactions in a serverless context.

This code sets up a Socket.IO server and client for testing, handling potential port conflicts by retrying server startup if necessary.

This set of functions provides functionality for file operations, including deletion, creation, reading, and closing, with associated error handling for potential issues such as permission problems or file non-existence. Additionally, there are methods for sending results or errors to the client, assuming that the $.sync() method has been called beforehand.
