Kattis Tool

About

kat is a simple command line tool written in Haskell to easily download and run the provided sample test cases on your machine.

Installation

Ensure you already have Haskell stack installed.

To install, clone this repository and run stack install.

Note this has only been tested to work on Linux, and will not (currently) work on Windows.

Usage

For usage, run kat --help:

$ kat --help
kat - Test Kattis solutions locally

Usage: kat [ --help | --version | COMMAND [ OPTIONS ] ]

Available options:
  --help, -h       Show this help message.
  --version, -v    Show program version.
  --lazy, -l       Abort running tests on first failure.

Available commands:
  test ID EXEC     Run test cases of the given problem ID on EXEC.
  get ID           Download test cases for the given problem ID.
                   This is automatically done by 'test'.
  clean            Remove all temporary files.

For example, to test your solution main.cpp on the problem with ID abc, you first need to compile your solution, then run kat test on it.

g++ -o ./main -O2 main.cpp
kat test abc ./main

If you passed all the test cases, you should see the following output:

$ kat test abc ./main

-- Test Case PASSED --

-- Test Case PASSED --

-- SUMMARY --
All test cases passed!

The test cases are downloaded into /tmp/kattis/. If for some reason the download was corrupted (which should never happen, it should just fail), you can run kat clean to clear the cached files.

If the test cases were previously downloaded and still exists, they will be reused on subsequent runs.

You need an internet connection to download the test cases. You can download and cache the files off-line using kat get ID.

Ideas

A list of features I may implement in the future:

• Submit solutions directly from command line
• Check floating point numbers to a certain precision
