INSTALLATION

Install using pip

Linux (use pip if default version of python is 3.x on your distro):

sudo pip3 install --user --upgrade competest

Windows:

Run Powershell/cmd as admin and type:

pip install competest

Alternatively, Windows users can download the latest competest.exe file from releases.

DESCRIPTION & USAGE

competest is a command line program to test competitive coding problems for test cases. It requires python 3.6+ to be installed. It is licensed under GPL-v3 License.

As of now, supported Languages are:

• C
• C++
• java
• python
• pypy
• exe(i.e. compiled executables)

Usage:

competest [OPTIONS] [python|java|pypy|exe] PROGRAM_FILE

Example:

competest python program1.py -t tests.json

If the test case file has the same name as the program file, -t option can be omitted. competest will then look for a json or a txt file with the same name as the program file in the same folder as the program file. If test case file is not found, it will thow an Error

competest python program1.py

TEST CASES FORMAT

The test case file should contain all the test cases that you want to test your code against.

Note: The test case format is decided based on the file extension so the file extension must be .txt or .json.

Test Cases can be written in 2 formats:

1. Test cases can be in .txt format

Single Test Case:

5
3 2 4 5 6

2
12

Note: input is followed by output and separated by a blank line.

Multiple Test Cases:

5
3 2 4 5 6

2
12

7
3 2 4 5 6 10 16

10

Note: Each test case is also separated by a blank line.

2. Test cases can also be in json format

Single Test Case:

[
    {
        "input":[
            "5",
            "3 2 4 5 6"
        ],
        "output":[
            "2",
            "1 2"
        ]
    }
]

Note: input and output are arrays of strings where each string is a line of input/output

Multiple Test Cases:

[
    {
        "input":[
            "5",
            "3 2 4 5 6"
        ],
        "output":[
            "2",
            "1 2"
        ]
    },
    {
        "input":[
            "7",
            "3 2 4 5 6 10 16"
        ],
        "output":["10"]
    }
]

OPTIONS

 -t, --test-cases FILENAME          File containing test cases.

 -a, --compiler-args ARGUMENTS      command line arguments to be passed to
                                    compiler(for compiled languages only)

 -h, --help                         Show this message and exit.

COMPILATION

You can pass extra arguments and flags to the compiler using -a option. Don't pass -o flag to C/C++ compiler as it is not required and handled by the tool itself.

The default compilation commands are:

Java

javac classname.java

C

gcc -O2 -lm filename.c

C++

g++ -O2 -lm filename.cpp

BUILD INSTRUCTIONS

To run competest directly use

python3 run.py

---

To run the tests use

python3 run_tests.py

---

To build competest binary (install pyinstaller first)

pyinstaller -F run.py

The executable will be saved in dist folder.

TODO

• Add a simpler test case format
• Improve Documentation
• Add more metadata to setup.py
• Add more language support
