# For a local module named "matrix"
from matrix import *
import unittest

# In order to use testing functionality you must create 
# a class inheriting 'unittest.TestCase' 
class test_matrix(unittest.TestCase):
    
    # Tests are functions 
    # Test names prefix with 'test'
    def test_multiply_vec_by_scalar(self):
        v = multiply_vec_by_scalar([1,1,1],2)
        self.assertEqual(v, [2,2,2])
        self.assertIsInstance(v, list)

# There are a few ways to run unittests
# Some ways allows for automatic tests detection
# The following way allows us to run the tests inside this 
# file by calling it as a normal .py file
