[New-bugs-announce] [issue35412] test_future4 ran no test

[STINNER Victor]

New submission from STINNER Victor <vstinner at redhat.com>:

Since bpo-34279 has been fixed, regrtest now logs a message when a test runs no test. I noticed that test_future4 logs such message:

...
0:05:23 load avg: 0.56 [152/412] test_future4
0:05:24 load avg: 0.56 [153/412] test_future5 -- test_future4 run no tests
...
2 tests run no tests:
    test_dtrace test_future4

I can reproduce the issue:

$ ./python -m test test_future4
(...)
test_future4 run no tests
(...)
Tests result: NO TEST RUN

The test has been added by:
commit 62e2c7e3dfffd8465a54b99fc6d3c2a60acab350

    Add regression test for future statements.  This adds eight files, but
    seven are not tests in their own right; these files are mentioned in
    regrtest.

... test removed by commit 3090694068670371cdbd5b1a3d3c5dbecc83835a.

    I forgot to svn add the future test


... I guess that it's related to:

commit 3c60833e1e53f6239825b44f76fa22172feb1790
Author: Christian Heimes <christian at cheimes.de>

    Patch #2477: Added from __future__ import unicode_literals
    
    The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.

(Other candidates: commit 342212c52afd375d93f44f3ecda0914d77372f26 and commit 7f23d86107dfea69992322577c5033f2edbc3b4f.)
