Unit test in Python not running

Question

I'm trying to test my code with unit tests, but when I try to run it it just says

Finding files... done.
Importing test modules ... done.
----------------------------------------------------------------------
Ran 0 tests in 0.000s
OK

Why isn't it working?

from Graph import Graph
import unittest
class GraphTest:
 def setUp(self):
 self.graph = Graph()
 for i in range(5):
 self.graph.addNode(i,"Node"+i)
 self.graph.addEdge(1,5,"Edge1,5")
 self.graph.addEdge(5,1,"Edge5,1")
 self.graph.addEdge(3,2,"Edge3,2")
 def test_Connected(self):
 self.assertTrue(self.graph.isConnected(1,5))
 self.assertTrue(self.graph.isConnected(5,1))
 self.assertTrue(self.graph.isConnected(3,2))
 self.assertFalse(self.graph.isConnected(2,3))
 self.assertFalse(self.graph.isConnected(1,4))
if __name__ == '__main__':
 unittest.main()

Answer 1

You should make your GraphTest a subclass of unittest.TestCase
