Here is an overview of what each subdirectory or file represents:

- `db/` - This directory contains mock data mimicking the actual database contents.
  - `users.json` - Represents a list of users in the system. Each entry contains user-specific information such as user ID, username, password hash, etc.
  - `messages.json` - Contains a list of messages exchanged between users. Each message entry includes the sender's and receiver's user IDs, message content, timestamp, etc.
- `requests/` - This directory contains mock requests that a client might send to the server.
  - `login.json` - Represents a user login request. It includes fields such as username and password.
  - `register.json` - Mimics a user registration request. Contains details such as username, password, email, etc.
  - `sendMessage.json` - Simulates a message sending request from a user to another user.
- `responses/` - This directory holds the expected server responses for the respective requests.
  - `login.json` - Represents a successful login response from the server. It typically includes a session token and user-specific information.
  - `register.json` - Simulates a successful registration response from the server, usually containing the new user's ID, username, etc.
  - `sendMessage.json` - Depicts a successful message sending response from the server, confirming the delivery of the message.

## JSON Format

All the data files in this directory are in JSON format. JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.

Here is a simple example of what a JSON file might look like:

```bash
  "users": [
    {
      "id": 1,
      "username": "user1",
      "password": "password1"
    },
    {
      "id": 2,
      "username": "user2",
      "password": "password2"
    }
  ]

```

In this example, "users" is an array of user objects. Each user object has an "id", "username", and "password".
