Hi Competitive Programming Community!!

I want to share with the entire competitive programming community my latest project: Quick Test CLI, which is a multiplatform open source tool to perform stress testing in competitive programming and that was inspired after watching the following screencasts: 1v1 Coding | 2020 Lockout Championship and How to test your solution in Competitive Programming, on Linux? Made by Errichto some time ago.

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

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

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

What Quick Test CLI provides vs. the traditional way of performing stress testing?​

  • Multi-platform
  • Supports several languages
  • Friendly user interface
  • You don't have to create or use tedious bash scripts
  • It can be a standard for the community
  • It is a collaborative project that can continue to grow for the benefit of the competitive programming community.

Quick Test CLI supports several types of tests:​

quicktest cmp | qt cmp​

It checks the correctness of the algorithm we want to verify by comparing it with a brute force solution which is usually very slow, but is 100% sure to provide the correct solution.

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, so the quicktest cmp command would not work correctly, in this case a script checker is used to verify the correctness of the algorithm.

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​

Verify that the code execution time does not exceed what is allowed, using a random generator for multiple test cases.

Note: In this scenario there is no slower solution with which to compare the correction.

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

Future Updates​

Feature for testing interactive problems is planned to be implemented in future versions

I will be grateful to receive feedback, requests for new features and requests for improvements

Don't forget to give it ⭐in the Github repository

Thanks!
