[issue22607] find by dichotomy the failing test

[Georg Brandl]

Georg Brandl added the comment:

I don't think this feature is generally useful enough to be included.  

* Since you need to modify the test code anyway (adding the try-except), it is probably just as much work to do the selection there.

* Why only add selection of subtests, and not of all tests?

In addition, the patch would have to be reworked: eval()ing an environment variable is not acceptable.

BTW, I think the commonly used term for this is "bisection".
