Stress Testing for Competitive Programming

This repository contains scripts for stress testing competitive programming solutions. The goal is to find hidden bugs and edge cases by generating random test inputs, running multiple solutions, and comparing outputs.

---

✅ Features

• Test Case Generator: Create random inputs within given constraints.
• Multiple Solutions Comparison: Compare outputs from a brute-force (correct) and an optimized solution.
• Automated Loop: Continuously run tests until a mismatch is found.
• Easy Setup: Simple to use with C++ solutions, can be adapted for other languages.

⚙️ Prerequisites

• C++ Compiler (g++)
• Basic knowledge of compiling and running C++ programs.
• Basic Knowledge of running bash file

---

🚀 How to Setup and Run

1. Clone the Repository and goto this directory

git clone https://github.com/mostafa-cse/Stress-Testing.git
cd Stress-Testing

2. Prepare Your Files

• gen.cpp → Generates test cases.
• bruteforces.cpp → Verified correct solution.
• efficient.cpp → Optimized or solution to test.

3: Run the bash file in this directory using the terminal

bash checker.sh

When a difference is found, the loop stops and shows the failing case.

🛠 How It Works

1. Generate random input.
2. Run bruteforces solution and efficient solution on the same input.
3. Compare outputs.
4. Stop when mismatch occurs → investigate bug.
