Issue: Add more tests for formatting floats and fractions #109546

vstinner

I would prefer to not load test_float in test_fractions just to get a filename.

+ @requires_IEEE_754
+ def test_float_format_testfile(self):
+ from test.test_float import format_testfile


I would prefer to just copy/paste the code to get the path here:
format_testfile=os.path.join(test_dir, 'formatfloat_testcases.txt')
I prefer to not make tests inter-dependents. Sometimes, just importing a test has side effects.

+ continue
+ line = line.strip()
+ if not line:
+ continue


I suppose that such logic is used in other files using formatfloat_testcases.txt. Is there a good place to share common code?
If we add mathdata/, can we add a helper function there which would iterate on the file and strip comments?

I was going to add it in test_float, but it is simple enough, so I just copied it.

+ if fmt == '%r':
+ continue
+ with self.subTest(fmt=fmt, arg=arg):
+ f = F(float(arg))


Maybe add a variable for fmt[1:].

+1 for the idea, and code changes LGTM.

Oh. I tried to backport this change to 3.11 to prepare backporting PR #109512 to 3.11 and 3.12, but the fractions module doesn't support all formatting syntax in 3.11:

ERROR: test_float_format_testfile (test.test_fractions.FractionTest.test_float_format_testfile) (fmt='%.1g', arg='10')
----------------------------------------------------------------------
Traceback (most recent call last):

^^^^^^^^^^^^^^^
TypeError: unsupported format string passed to Fraction.__format__

So this change cannot be backported.
