The Toll Plaza project is a learning-oriented application designed to simulate a toll system with entry and exit points. The primary goal of this project is to deepen the understanding of testing methodologies in Node.js using Jest. The project includes two main routes: /toll/entry and /toll/exit, which handle the logic for vehicles entering and exiting the toll plaza.

In this project, I focused on the following learning objectives:

• ✅ Understanding the fundamentals of Jest for testing JavaScript applications.
• ✅ Learning how to implement Jest mocks to simulate external dependencies.
• ✅ Using SuperTest for end-to-end testing of HTTP routes.
• ✅ Implementing Jest Spy functions to monitor and manipulate function calls within the application.
• ✅ Writing optimal and efficient test cases to ensure comprehensive test coverage.

The following routes are implemented in this project:

• POST /toll/entry

  • Handles vehicle entry into the toll system.
  • Records entry time and toll point.

• POST /toll/exit

  • Handles vehicle exit from the toll system.
  • Calculates the toll fee based on the entry and exit points.

This project is not configured for production use. It is intended for educational and development purposes only.

To set up the project locally, follow these steps:

1. Clone the repository to your local machine:

   git clone https://github.com/Kashif-Kamran/toll-plaza.git

2. Navigate to the project directory and install the necessary dependencies:

   npm install

3. Start the development server:

   npm run start:dev`

This project is developed solely for educational purposes. It is intended as a learning tool to explore and practice testing techniques in a Node.js environment. The functionality and implementations may not be suitable for production use.
