Human-readable name of test case does not appear in results.json

[bryceadam1]

Description
Naming test cases with a new-line character on the first line causes the name of the function to be placed in the results.json file instead of the human-readable name in the docstring of the testcase.

To Reproduce
Create a testcase and name it with a docstring that has a new-line character on the first line. This file is called tests.py.

import unittest
from gradescope_utils.autograder_utils.decorators import weight, number

class TestAutograder(unittest.TestCase):
    @weight(1.0)
    @number("1")
    def test_prob1(self):
        """
        A human-readable name.
        """
        pass

Running the above with the JSONTestRunner provided in gradescope_utils produces the following results.json:

{
    "tests": [
        {
            "name": "test_prob1 (tests.TestAutograder)",
            "score": 1.0,
            "max_score": 1.0,
            "number": "1"
        },
    ],
    "leaderboard": [],
    "execution_time": "0.00",
    "score": 10.0
}

Expected behavior
Should have produced the following results.json file:

{
    "tests": [
        {
            "name": "A human-readable name.",
            "score": 1.0,
            "max_score": 1.0,
            "number": "1"
        },
    ],
    "leaderboard": [],
    "execution_time": "0.00",
    "score": 10.0
}

Additional context
Removing the new-line character seems to fix the issue. I.e. the following produces the expected result.

import unittest
from gradescope_utils.autograder_utils.decorators import weight, number

class TestAutograder(unittest.TestCase):
    @weight(1.0)
    @number("1")
    def test_prob1(self):
        """A human-readable name."""
        pass

This also seems to only be the case inside of Gradescope's docker containers used for actually grading student submissions. This did not happen when I ran the code on my macbook.

Hi @bryceadam1! Sorry for the delay in getting back to you. I think this behavior is from the unittest library itself (we are simply calling test.shortDescription to populate this), so if you're seeing different behavior on your Macbook I wonder if the Python versions are different? We are now defaulting to Python 3 everywhere, and now that we have different Ubuntu base image versions newer versions might have newer versions of Python 3

If you can, please let us know if you are still seeing this issue. Thank you!
