Hi, Competitive Programming community!

I want to share my latest project with the competitive programming community: Quick Test CLI. It is a multi-platform, open-source tool for stress testing in competitive programming. I got the idea after watching these screencasts by Errichto: 1v1 Coding | 2020 Lockout Championship and How to test your solution in Competitive Programming, on Linux?.

📦Source Code: https://github.com/LuchoBazz/quicktest

📖Docs: https://luchobazz.github.io/quicktest

🚀 Installation: https://luchobazz.github.io/quicktest/docs/getting-started/installation

What does Quick Test CLI provide compared to the traditional way of stress testing?​

  • Multi-platform
  • Supports several languages
  • Friendly user interface
  • You don't need to create or use long bash scripts
  • It can become a standard for the community
  • It is a collaborative project that can keep growing for the benefit of the competitive programming community

Quick Test CLI supports several types of tests:​

quicktest cmp | qt cmp​

It checks if the algorithm is correct by comparing it with a brute force solution. The brute force solution is usually very slow, but it should always give the correct answer.

quicktest cmp --target-file=main.cpp --correct-file=correct.cpp --gen-file=gen.cpp
# Or shorter:
qt cmp -t main.cpp -c correct.cpp -g gen.cpp

quicktest check | qt check​

In some problems, more than one answer is accepted. In that case, the quicktest cmp command may not work well. Instead, you can use a checker script to verify the solution.

quicktest check --target-file=main.cpp --checker-file=correct.cpp --gen-file=gen.cpp
# Or shorter:
qt check -t main.cpp -c check.cpp -g gen.cpp

quicktest stress | qt stress​

Checks that the running time does not exceed the time limit, using a random generator for many test cases.

Note: In this scenario, there is no (slow) correct solution to compare against.

quicktest stress --target-file=main.cpp --gen-file=gen.cpp
# Or shorter:
qt stress -t main.cpp -g gen.cpp

Future Updates​

A feature for testing interactive problems is planned for future versions.

I would be grateful for feedback, feature requests, and suggestions for improvements.

Don't forget to give it a ⭐ on the GitHub repository.

Thanks!
