It seems GitHub actions does not have the capabilities for running this test and must be run by a user. Any advice @terryjreedy (If I remember correctly you contributed quite a lot to turtle)

This would have to be a user only test.

The first failure is trying to open couldn't open a non-existent file. "D:\a\cpython\cpython\Lib\test/imghdrdata/python.gif": no such file or directory" Not on my system either for installed or repository versions. The others are for turtle.getscreen()._xxxx()calls raisingturtle.Terminator`. The latter also happens on my Windows system. Did the tests run for you? If so, which OS and which exact binary. What is the initial line when you run interactively?

To run just the test file, it needs the following added at the end.

if __name__ == '__main__':
    unittest.main()

I don't know anything in particular about testing turtle. I have only worked with turtledemo. Ping whoever has worked on test_turtle if not already.

@StanFromIreland Is there a specific reason you closed this rather than leave open for someone else to fix?

For anyone else: see my comment above. The new gui-needing test class could and should be added to the existing test_turtle.py by using support.requies('gui') in def setUpClass, as in IDLE tests. The missing image test could be deleted or fixed by finding the right url. I think IDLE somewhere references the file meant, and idlelib.icons has files. I neglected above to mention any or which turtle.getscreen().xxx() calls failed. turtle.getscreen()._blankimage() works for me today.
