Not sure if it's me or not, but having that many files to review makes my GH interface crash (or load very slowly). Would it be possible to split this PR, at least per folders? just so that 1) it reduces the number of review requests 2) it helps us to review if possible?

I have already already created 15 other PRs for groups of files with significant number of changes. But it is not worth to create a PR for 5 changed lines in 2 files.

🤖 New build scheduled with the buildbot fleet by@picnixz for commitcc1f37a 🤖

If you want to schedule another build, you need to add the🔨 test-with-buildbots label again.

(Oh maybe I shouldn't have scheduled build bots if you had other commits... sorry in advance, though I can look at the buildbots status page)

I was checking test_idle when I found this PR in my mailbox. (EDIT) 10 rather than just 2 idle tests can be changed and I want to backport them. I think it easiest if I make a separate PR (DONE,#129213) attached to the same issue I copied the 2 changes made here so there should be no conflict.

EDIT The IDLE changes are merged and backported.

I non-recursively searchedself.assert.*(issubclass|hasattr|startswith|endswith) inF:\dev\3x\Lib\test\test_t*.py (with IDLE) and found the same change candidates in thetest_t*.py files included here (and only a couple of false positives). The replacements all looked right.

This is the 1 AMD64 Android failure.

======================================================================FAIL: testAssertHasAttr (test.test_unittest.test_case.Test_TestCase.testAssertHasAttr)----------------------------------------------------------------------Traceback (most recent call last):  File "/data/user/0/org.python.testbed/files/python/lib/python3.14/test/test_unittest/test_case.py", line 803, in testAssertHasAttr    with self.assertRaises(self.failureException) as cm:         ~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^AssertionError: AssertionError not raised

The patch was initially created in 2016. It was then updated few years later, and just before creating this PR. Since the IDLE tests are located outside of theLib/test tree, I missed new tests there.

Not sure what happened before with Android and iOS, but they both seem fine now.

It was an issue in different tests which was fixed by#129133.

No need to trigger buildbots. This PR is not emergent. It will be merged after merging all related PRs. Some changes can be extracted into separate PRs (like IDLE's).

There have been practically no conflicts in the last few months. This means that this PR affects a very small part of the code that is actively changing. So I plan to merge this PR without backporting to 3.13. Probability of conflicts in future backports to 3.13 is low.

Thanks@serhiy-storchaka for the PR 🌮🎉.. I'm working now to backport this PR to: 3.14.
