+# Internal API Test Server
+
+This directory contains the internal API test server implementation that replaces the third-party `json-server` dependency.
+
+## Files
+
+- `lib/test-server.js` - Main TestServer class implementation
+- `bin/test-server.js` - CLI script to run the server standalone
+
+## Usage
+
+### As npm script:
+
+```bash
+npm run test-server
+```
+
+### Directly:
+
+```bash
+node bin/test-server.js [options] [db-file]
+```
+
+### Options:
+
+- `-p, --port <port>` - Port to listen on (default: 8010)
+- `--host <host>` - Host to bind to (default: 0.0.0.0)
+- `db-file` - Path to JSON database file (default: test/data/rest/db.json)
+
+## Features
+
+- **Full REST API compatibility** with json-server
+- **Automatic file watching** - Reloads data when db.json file changes
+- **CORS support** - Allows cross-origin requests for testing
+- **Custom headers support** - Handles special headers like X-Test
+- **File upload endpoints** - Basic file upload simulation
+- **Express.js based** - Uses familiar Express.js framework
+
+## API Endpoints
+
+The server provides the same API endpoints as json-server:
+
+### Users
+
+- `GET /user` - Get user data
+- `POST /user` - Create/update user
+- `PATCH /user` - Partially update user
+- `PUT /user` - Replace user
+
+### Posts
+
+- `GET /posts` - Get all posts
+- `GET /posts/:id` - Get specific post
+- `POST /posts` - Create new post
+- `PUT /posts/:id` - Replace specific post
+- `PATCH /posts/:id` - Partially update specific post
+- `DELETE /posts/:id` - Delete specific post
+
+### Comments
+
+- `GET /comments` - Get all comments
+- `POST /comments` - Create new comment
+- `DELETE /comments/:id` - Delete specific comment
+
+### Utility
+
+- `GET /headers` - Return request headers (for testing)
+- `POST /headers` - Return request headers (for testing)
+- `POST /upload` - File upload simulation
+- `POST /_reload` - Manually reload database file
+
+## Migration from json-server
+
+This server is designed as a drop-in replacement for json-server. The key differences:
+
+1. **No CLI options** - Configuration is done through constructor options or CLI args
+2. **Automatic file watching** - No need for `--watch` flag
+3. **Built-in middleware** - Headers and CORS are handled automatically
+4. **Simpler file upload** - Basic implementation without full multipart support
+
+## Testing
+
+The server is used by the following test suites:
+
+- `test/rest/REST_test.js` - REST helper tests
+- `test/rest/ApiDataFactory_test.js` - API data factory tests
+- `test/helper/JSONResponse_test.js` - JSON response helper tests
+
+All tests pass with the internal server, proving full compatibility.
