The following is what I am using and it appears to work:
=========================================================
from testscenarios import TestWithScenarios
import right_justify
scenario0 = ('string0', {
'input': "Monty Python",
'expected_result0': 70})
scenario1 = ('string1', {
'input': "She's a witch!",
'expected_result0': 70})
scenario2 = ('string2', {
'input': "Beware of the rabbit!!! She is a vicious beast who will rip"
" your throat out!",
'expected_result0': 70})
class TestRightJustify(TestWithScenarios):
'''Tests for the function, "right_justify(a_string)", in the "right_justify
module".'''
scenarios = [scenario0, scenario1, scenario2]
# Tests follow...
==========================================================
I am using Python 3.5.2. Before I installed testscenarios, I first
installed testtools as that was listed as a dependency for
testscenarios.
As you can see, I did not have to explicitly import unittests, so thus
my questions. So what is actually happening here?
