我的简单python unittest案例未按预期运行

Question

Created this simple unit test as shown bellow

calculator_tester.py

import unittest
class MathsTest(unittest.TestCase):

    def test_createOperation(self):
        operation = Mathoperation()

This is the only test file I have created and Note there doesnot exist a class call Mathoperation() that is defined inside the test method. n When running this sample test code using the python test runner

python -m unittest

output:

----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

Expectation:

I was expecting the test case to run and throw NameError: global name Mathoperation is not defined. But the test case didn't run.

What is the sample test case not running. I am running it on python version 2.7.12

Answer 1

Test discovery looks for files matching the glob pattern test*.py by default. Your test doesn't match that pattern. Rename it, or specify the test file explicitly.
