python3 class generates same random value with unittest

This is an exercise from exorcism.io that I need to generate a random name with the class is initialized. One of the unit test cases is failing because the random string is same across two instances of the class. If I run the code outside of unittest, it appears to work correctly. Could it be that the var is pointing to the same address space in unittest?

import string
import random
import unittest


class Robot(object):
    def __init__(self):
        self.name = None
        self.reset()
        print('Name at Init', self.name)

    def reset(self):
        for _ in range(5):
            new = random.choice(string.ascii_uppercase) + random.choice(string.ascii_uppercase) + str(random.randint(100, 999))

        self.name = new


class SimpleTest(unittest.TestCase):
    if not hasattr(unittest.TestCase, "assertRegex"):
        assertRegex = unittest.TestCase.assertRegexpMatches

    name_re = r'^[A-Z]{2}\d{3}$'

    def test_names(self):
        # Set a seed
        seed = "This is some seed text"

        # Initialize RNG using the seed
        random.seed(seed)

        # Call the generator
        robot = Robot()
        name = robot.name

        # Reinitialize RNG using seed
        random.seed(seed)

        # Call the generator again
        robot.reset()
        name2 = robot.name
        self.assertNotEqual(name, name2)
        self.assertRegex(name2, self.name_re)



if __name__ == '__main__':
    unittest.main()
    # print(Robot().name == Robot().name)   # Returns False
