I have gone through docs but did not understand unittesting in real sense in python.
i have a test code can anyone will tell me how to do unittestng on it?
a = 1
b = 2
def test():
c = a + 2
if c > 5:
z = 7
else:
z = 8
answer = b + z
return answer
To test your test() method you should create a test file like this
import unittest
from your_file import test
class TestMethodTestCase(unittest.TestCase):
def test_01a(self):
""" test the test method"""
self.failUnlessEqual(9, test(a=4, b=2)) # here you write all the use case you need to be sure that your method is correctly doing the job
self.failUnlessEqual(10, test(a=1, b=2))
self.failUnlessEqual(11, test(a=5, b=3))
if __name__=="__main__":
unittest.main()
with your test() method defined like this :
def test(a=1, b=2):
c = a + 2
if c > 5:
z = 7
else:
z = 8
answer = b + z
return answer
Have a look to python unittest documentation
Unit testing doesn't mean much more than just automated checking of the output of various functions in your code when they are given certain values. Basically, you just want to make sure that those tests don't break when you're changing things.
__main__ trick is used to prevent modules from executing if you import them.
test(a, b)). In that case you'd try it with several different arguments and check that it returns the expected value in all cases.
