Demo solutions with unit testing for some problems from https://open.kattis.com
-
Linux/Mac/WSL (Windows Subsystem Layer) bash terminal is preferred along with language specific tools (compiler/interpreter, etc.) properly installed
-
On Windows g compiler is required to compile and run C and C code from command prompt
- g compiler for Windows can be downloaded from https://nuwen.net/mingw.html; extract it into C:\ drive as shown in the instructions here: https://nuwen.net/mingw.html#install
-
pytest Python3 package for testing Python3 solutions
pip3 install -U pytest
pip3 install -U mypy
- demos are provided in the following several languages
- follow the instructions based on your language and operating system
- open a terminal on Mac/Linux/WSL or cmd prompt on Windows
- change working directory to a problem folder, e.g.
cd cold/C
- compile using g or use provided Makefile
g -std=c 14 cold.cpp
make
- run unit testing; user provided test cases
- on Mac/Linux, either run the program with test argument or use the provided Makefile
./a.out test
make unit_test
- on Windows:
a.exe test
- run kattis provided sample test cases e.g. if 1.in and 1.ans are sample test files:
- on Mac/Linux/WSL Terminal
cat 1.in | ./a.out | diff - 1.ans
make kattis_test
- on Windows cmd prompt:
> type 1.in | a.exe > out1.txt
> FC out1.txt 1.ans
- open a terminal on Mac/Linux/WSL or cmd prompt on Windows
- change working directory to a problem folder, e.g.,
cd cold/python3
- run unit tests; user provided test cases
- several different ways...
python3 cold.py test
python3 test_cold.py
python3 test_unit_cold.py
pytest # make sure pytest is installed
python3 -m unittest
- open terminal
- change current working directory to OOP folder inside problem/python3 folder
- run the following commands
mypy --strict <module>.py
mypy --strict test_<module>.py
pytest <module.py>
python3 -m unittest
- run kattis provided sample test cases e.g. if 1.in and 1.ans are sample test files
cat 1.in | python3 cold.py | diff - 1.ans
- on Windows cmd prompt
type 1.in | python3 cold.py > out1.txt
FC out1.txt 1.ans
- open a terminal on Mac/Linux/WSL or cmd prompt on Windows
- change working directory to a problem folder
- run unit testing with your own test cases
- uses Jest Unit Testing Framework
- run the following commands on a Terminal
cd cold
npm install
npm run jest
npm run kattis_test
- run kattis provided sample test cases e.g. if 1.in and 1.ans are sample test files
- on Mac/Linux Terminal
cat 1.in | node cold.js | diff - 1.ans
- on Windows cmd prompt:
type 1.in | node cold.js > out1.txt
FC out1.txt 1.ans
- open a terminal on Mac/Linux/WSL or cmd prompt on Windows
- change working directory to a problem folder, e.g.
cd cold
- compile using gcc
gcc cold.c
- run unit testing; user provided test cases
- write and use a Makefile as demonstrated in C section
./a.out test
- run kattis provided sample test cases e.g. if 1.in and 1.ans are sample test files
- on Mac/Linux Terminal:
cat 1.in | ./a.out | diff - 1.ans
- on Windows cmd prompt
type 1.in | a.out > out1.txt
FC out1.txt 1.ans
