CP-test

A tool to generate test-cases for competitive programming. With it, you can also execute your code on generated test-cases and compare it with other code automatically.

What it can do?

• Generate random test-cases
• Auto-generate .tcs syntax files from problem statements using the testcase-syntax skill
• Run code (supports C11, C++14, Python 3) automatically on these test-cases
• Run two codes simultaneously and compare results to detect corner cases
• Generate HackerRank problem-setting style test-case zip packages

Why?

• Solely for generating test-cases
• To verify code runs properly and avoid runtime errors
• To compare optimized code against brute-force code on random inputs

Usage

To generate test-cases (E.g.: 5 test-cases):

python3 testcode.py -T testcase_syntax.tcs -N 5

To generate test-cases and run your code on them:

python3 testcode.py -T testcase_syntax.tcs -I1 my_code.cpp

To generate test-cases, run two codes, and compare output:

python3 testcode.py -T testcase_syntax.tcs -I1 my_code.cpp -I2 my_bruteforce.py

To generate HackerRank style test-cases zip:

python3 testcode.py -T testcase_syntax.tcs -I1 my_code.cpp -C configs/hackerrank.ini

• Default -N is 10. Pass -N <count> to adjust.
• Default config is configs/default.ini. Use -C to specify custom config.
• Pass .tcs syntax file with -T. Refer to TCSYNTAX.md for reference.
• Skill: Use skills/testcase-syntax/SKILL.md to automatically translate problem statements and constraints into .tcs files.
• See AGENTS.md for AI agent testing guidelines and workflows.

Supported languages

• C11
• C++14
• Python3
