SyntaxError not catched when named explicte but unittest does

[buhtz]

My current environment: Green 3.4.0, Coverage 6.2, Python 3.9.4 on Windows10

I run a test by naming it explicit:

C:\Users\buhtzch\tab-cloud\_transfer\greenbug>py -3 -m green tests.test_my

Ran 0 tests in 0.316s using 8 processes

No Tests Found

There are two problems about that output:

1. The test ist not found. (Run 0 tests)
2. A SyntaxError is not thrown.

Unittest itself shows this output

C:\Users\buhtzch\tab-cloud\_transfer\greenbug>py -3 -m unittest tests.test_my

SyntaxError: invalid syntax

This is the MWE. The file is in a folder named tests and there is also an empty __init__.py in the same folder.

import unittest

class TestMY(unittest.TestCase):
    """
    """
    def test_valid_scores(self):
        """All items with valid values."""
        #self.assertTrue(True)
        X X

The last line should cause a syntax error.

When you fix the syntax of the MWE the test is found by green. So I think the not catched SyntaxError also causing the missing test.

The fix for this was included in version 3.4.1. See #256 for details on the fix. Thanks for your detailed report! 😄

Sorry I would reopen this.

I have nearly the same problem with a ModuleNotFoundError.

When I explicite name the test via green tests.test_reader no tests found and no error is thrown.

When I do discover via green the (expected) ModuleNotFoundError is thrown.

[buhtz]

The ModuleNotFoundError is still there and not catched

@buhtz Do you have any information on how to reproduce this?

• Operating System name & version
• Output of green --version
• Code to reproduce the failure

/cc @sodul for followup if desired
