This is a simple Go web service that provides a basic API for retrieving book information. It's built using the chi router and serves hardcoded book data from memory.

Project Structure

main.go: Application entry point, sets up the HTTP server and defines the /books/{id} endpoint.
internal/handlers/book_handler.go: Contains the BookHandler responsible for processing requests to the /books/{id} endpoint. It uses an in-memory list of books.
internal/models/book.go: Defines the Book struct used to represent book data.

Getting Started

Prerequisites

Go (version 1.16 or higher recommended)

Running the Application

Clone the repository:
```
git clone <repository_url>
cd testing-go-example
```
(Note: Replace <repository_url> with the actual repository URL if this project were hosted.)
Run the server:

```
The server will start on http://localhost:3000.
