HackerRank Test-Case Generator

Project description

Generate test cases for your HackrRank challenge. You need your solution algorithm, input format and constraints only. Generate the zipped file and upload :)

Installation

$ pip install hackgen

Example usage

>>> import random
>>> from hackgen import TestInputFormat, TestGenerator, Language
>>> class ClockDelayInputFormat(TestInputFormat):
>>>     """
>>>     Input format of Clock Delay challenge.
>>>     https://www.hackerrank.com/contests/hourrank-28/challenges/clock-delay
>>>     """
>>>
>>>     # difficulty levels with test file number
>>>     # difficulty level is [0-9]
>>>     __diff = [(5, 10), (10, 30), (50, 100), (100, 300), (100, 300),
>>>               (300, 600), (600, 900), (800, 1000), (900, 1000), (950, 1000)]
>>>
>>>     def inputs(self, difficult_level: int) -> None:
>>>         q = random.randint(*self.__diff[difficult_level])  # number of test cases
>>>         print(q)
>>>         for n in range(q):
>>>             # constraints for h1 m1 h2 m2 k
>>>             h1 = random.randint(0, 23)
>>>             m1 = random.randint(0, 60)
>>>             h2 = random.randint(h1, 24)
>>>             k = random.randint(h2 - h1 + 1 if h1 == h2 else h2 - h1, 24 - h1)
>>>             m2 = random.randint(0, (m1 if h1 + k == h2 else 60))
>>>             print(h1, m1, h2, m2)
>>>             print(k)
>>>
>>> # input format instance
>>> input_format = ClockDelayInputFormat()
>>>
>>> # try with Language.java('Logic') also
>>> test_generator = TestGenerator(10, input_format, Language.python('logic'), "ClockDelay")
>>> test_generator.run()
