🤖 Moving-Robot Simulator

This Java-based Robot Simulator lets you control a robot in a 2D room using simple text commands. It supports movement, pen up/down drawing, grid printing, and boundary validation. Tests and coverage are integrated using JUnit and JaCoCo.

🚀 Getting Started

📋 Prerequisites

• Java 8+
• Maven 3+

📦 Install and Run

git clone https://github.com/mohammedsohail-dev/QAtesting.git
cd Moving-Robot-main
mvn clean compile

🧪 Testing & Coverage ✅ Run Unit Tests

mvn test

Uses JUnit 4 (for RobotTest.java) and JUnit 5 (QATest.java).

JUnit Vintage engine bridges the two.

📊 Generate JaCoCo Coverage Report

mvn clean test
mvn package

Then open the report:

target/site/jacoco/index.html

View detailed method and line-level coverage. 💡 Sample Commands

I 5
D
M 3
R
M 2
C
P

Expected output:

Robot moves 3 steps forward with pen down.

Turns right and moves 2 steps.

Room grid printed with * marking the path.
