NOTE In the following days this will get archived and rewritten in bash (Linux, macOS) and possibly batch (Windows).

local-test

Portable local testing software (and test case generator TODO: implement this) written in Python for competitive programming in C++.

Platform support

Unix-like (e.g. macOS, Linux) uses bash and Windows uses Command Prompt.

platform	Unix-like	Windows	WSL2
support	✔️	✔️	❌
shell	bash	cmd	bash

Usage

example folder structure

.
└── foo/
    ├── bar-tests/
    │   ├── 0.in
    │   └── 0.out
    └── bar.cpp

output generated with -h

usage: lt.py [-h] -p PROGRAM [-c]

optional arguments:
  -h, --help            show this help message and exit
  -p PROGRAM, --program PROGRAM
                        program pathname
  -c, --compile         compile program (default=False)

Unix-like

python3 $lt/lt.py -p bar.cpp -c
For simplicity, setup an environment variable for your local-test directory.

echo "export VARIABLE_NAME=value" >> ~/.bash_profile

Windows

python %lt%\lt.py -p bar.cpp -c
Unless local-test directory is an environment variable ("lt"), replace "%lt%\lt.py" with its pathname.

Environment Variables > System variables > New

Writing test cases

IMPORTANT Make sure to have matching newlines, otherwise correct output might flag your program as defective. Example below.

bar.cpp

#include <cstdio>
using namespace std;

int main() {
    int n;
    scanf("%d", &n);
    printf("%d\n", n);
}

^ Newline character present

0.in

66

^ Would work without newline

0.out

66

^ Newline present

## Why Python?

SIO2 (used by POI (POI's SIO2 link)) itself is partially written in Python. Honestly, I found joy writing Python for a change. BTW check out similar testing program written in bash shell (link).

Configuration - config.json
