Python Checktestdata

Checktestdata is a tool to verify the syntactical integrity of test cases in programming contests like the ACM ICPC. It allows you to specify a simple grammar for your testdata input files, according to which the testdata is checked.

— Checktestdata

This is a Python 3.10 compatible reimplementation of the checktestdata program.

Documentation

Installation

Requirements:

  • PyPy >= v7.3.15 (preferred)
  • CPython >= 3.10 (alternative)

The package can be installed directly from pypi:

pypy3 -m ensurepip
pypy3 -m pip install checktestdata
pip install checktestdata

Use

You can use this program to run .ctd validators in the same way as the checktestdata binary:

pyctd validator.ctd [-d | --debug] < testcase

You can also use the programm to convert .ctd files into standalone python applications:

pyctd validator.ctd --convert [name] [-d | --debug]

Extensions

This checktesdata implementation supports the --constraints_file argument and can be used with BAPCtools to check the constraints of a problem.
