About

jjm is a cli tool that simplifies testing your code against input samples from leetcode-like services. This works kind of like online judgment systems: provide input samples, answers and test your code.

NOTE: works only for python now.

Some details for current version (0.1.2)

The commands are:

$ jjm --help                                                                                     
usage: jjm [-h] {init,test,gen_in,sample,run} ...

positional arguments:
  {init,test,gen_in,sample,run}
    init                create and initialize problem's working directory.
    test                run code and compare answer from test case files with program's results.
    gen_in              generate test case file(s).
    sample              show the sample of the test case file.
    run                 run the code. Results are stored in 'out' folder.

options:
  -h, --help            show this help message and exit

init <name> generates the problem's directory with cases and out directories. out directory is used only for the jjm itself (previous results of running your solution are stored in here).

run <file> runs your code with data given in test_case .toml files in cases folder

test <file> runs the program against cases in cases folder and compares results.

gen_in <list of filenames> generates specified test files in cases folder. Extensions are ignored (i.e jjm gen_in 1.toml Would produce 1.toml.toml file with default config. See jjm sample).

sample prints basic sample for a test_case file

$ jjm sample
#  this is the example of case file
#  .toml format
[main]
in = ""
out = "?"  # ? - output is not specified
time = 1   # TLE timeout. Optional (1 is default) 

Installing

I haven't uploaded jjm to PyPI, you can install it via pip or pipx (which i prefer for CLIs):

git clone https://github.com/rasputyashka/jjm.git jjm
cd jjm
pipx install .  # see how to install pipx

Usage example

$ jjm init day7 example myinput wa_example  # for demo, i won't edit myinput (it will contain default values)
$ cd day7
$ echo "print(int(input()) * 2)" > sol.py   
$ nvim cases/example.toml # edit in="12", out="24"
$ nvim cases/wa_example.toml # edit in="12", out="24"
$ jjm test sol.py
example.toml - AC
myinput.toml - Output Not Specified
wa_example.toml - WA
Expected: 23
Got:      24
# cat out/myinput if you want to see the answer in case you haven't specified it.
