Basic unittest TestCase

Question

I have written the below code to test a basic unittest case for learning. When I execute the below code. I do not get any output. Could someone let me know what could be issue.

import unittest
 class test123(unittest.TestCase):
 def test1(self):
 print "test1"
 if __name__ == "main":
 x=test123()
 x.test1()
 unittest.main()

• idjaw: It should be if __name__ == "__main__": and all you have to do is call unittest.main(). You don't need to instantiate your class. The unittest.main() handles everything for you. Revise the documentation.

Answer 1

your code should look like this:

import unittest
class test123(unittest.TestCase):
 def test1(self):
 print "test1"
if __name__ == "__main__":
 unittest.main()

hence it is name and main with two underscores at the start and end, when you change it and run it with your code then you will get an error with using:

x = test123()
x.test1()
ValueError: no such test method in <class '__main__.test123'>: runTest

Answer 2

In your test you need two things:

1. Define your test function with 'test'
2. You need a expected result

test.py

import unittest
class TestHello(unittest.TestCase):
 def test_hello(self): # Your test function usually need define her name with test
 str_hello = 'hello'
 self.assertEqual(str_hello, 'hello') # you need return a expected result
 def test_split(self):
 str_hello = 'hello world'
 self.assertEqual(str_hello.split(), ['hello', 'world'])
if __name__ == '__main__':
 unittest.main()

for execute use:

python -m unittest test

out:

stackoverflow$ python -m unittest test
