minitest 1.3.3

Minitest is inspired by Ruby minispec.

This project is inspired by Ruby minispec, but now it just implement some methods including:

must_equal, must_true, must_false, must_raise.

And some other useful functions:

p, pp, pl, ppl, length, size, inject.

How to use

install:

pip install minitest

code:

if __name__ == '__main__':
    # import the minitest
    from minitest import *

    import operator

    # declare a variable for test
    tself = get_test_self()
    # you could put all your test variables on tself
    # just like declare your variables on setup.
    tself.jc = "jc"

    # declare a test
    with test(object.must_equal):
        tself.jc.must_equal('jc')
        None.must_equal(None)


    with test(object.must_true):
        True.must_true()
        False.must_true()

    with test(object.must_false):
        True.must_false()
        False.must_false()

    # using a funcation to test equal.
    with test("object.must_equal_with_func"):
        (1).must_equal(1, key=operator.eq)
        (1).must_equal(2, key=operator.eq)

    def div_zero():
        1/0

    # test exception
    with test("test must_raise"):
        (lambda : div_zero()).must_raise(ZeroDivisionError)
        (lambda : div_zero()).must_raise(ZeroDivisionError, "integer division or modulo by zero")
        (lambda : div_zero()).must_raise(ZeroDivisionError, "in")

Other useful function

p, pp, pl, ppl, length, size, these four functions could been used by any object.

p is a print function. This function will add variable name as the title. code:

value = "Minitest"
# add a title 'value : ' automatically.
value.p()                       # value : Minitest

# or you can give a string as title.
value.p("It is a value:")       # It is a value: Minitest

# if you don't want a title, use the parameter
value.p(auto_get_title=False)   # Minitest

pp is another print function which will invoke the pprint.pprint function. Its parameters are just like the p. code:

value = "Minitest"
value.pp()                      # value :
                                # 'Minitest'

value.pp("It is a value:")      #  It is a value:
                                # 'Minitest'

value.pp(auto_get_title=False)  # 'Minitest'

pl is another print function which will print the file path and line NO. And some editors support to go to the line of that file, such as Sublime2. Its parameters are just like the p. Notice, it will print new line firstly, since in some case, there will be other string before file path, which cause some editor cannot jump to the location.

code:

value = "Minitest"
value.pl()                      #
                                #     File "/Users/Colin/work/minitest/test.py", line 72
                                # value : Minitest

value.pl("It is a value:")      #
                                #     File "/Users/Colin/work/minitest/test.py", line 73
                                #  It is a value: Minitest

value.pl(auto_get_title=False)  #
                                #     File "/Users/Colin/work/minitest/test.py", line 74
                                # Minitest

ppl is another print function which will print the file path and line NO. It almost like pl except print value in another new line. Notice, it will print new line firstly. code:

value = "Minitest"
value.ppl()                     #
                                #     File "/Users/Colin/work/minitest/test.py", line 76
                                # value :
                                # 'Minitest'

value.ppl("It is a value:")     #
                                #     File "/Users/Colin/work/minitest/test.py", line 77
                                #  It is a value:
                                # 'Minitest'

value.ppl(auto_get_title=False) #
                                #     File "/Users/Colin/work/minitest/test.py", line 78
                                # 'Minitest'

length and size will invoke len function for the caller’s object. code:

[1,2].length()                  # 2, just like len([1,2])
(1,2).size()                    # 2, just like len((1,2))

inject_customized_must_method or inject function will inject the function which you customize. Why do I make this function? Since in many case I will use numpy array. When it comes to comparing two numpy array, I have to use:

import numpy
numpy.array([1]).must_equal(numpy.array([1.0]), numpy.allclose)

For being convient, I use inject_customized_must_method or inject function like:

import numpy
inject(numpy.allclose, 'must_close')
numpy.array([1]).must_close(numpy.array([1.0]))
