Mock Library Implementation

Description

Welcome to the Mocking Library project! This project showcases how to effectively mock Java libraries in a Spring Boot application using a Java agent with Byte Buddy. It's a comprehensive guide to setting up and running a mock environment for your Java applications.

Structure

Here's a quick rundown of the project structure:

• app/: Contains the Spring Boot application.
• agent/: Houses the Java agent that intercepts and mocks library functions.
• docker-compose.yml: Docker Compose configuration to run both the application and the agent seamlessly.

How to Build and Run

Follow these steps to get the project up and running:

1. Build the Docker image

   docker-compose build 

2. Start the containers:

   docker-compose up

3. Test the application by sending a POST request:

   curl -X POST http://localhost:8080/api/createNewPost -H "Content-Type: application/json" -d '{"post_name":"test-post","post_contents":"This is a test post"}'

Environment Variables

To configure the application, you'll need to set the following environment variables:

• HT_MODE: The mode for the Java agent. It can be set to either RECORD or REPLAY.
