Description (last modified by )
- When testing the file
""" EXAMPLES: The name blah is undefined:: sage: blah+blah blahblah Here's a doctest that is out of tolerance:: sage: 100+10000000000 # abs tol 0.1 10000000000 sage: 1+1 2 """
I get
File "/Users/marcostreng/tmp/test.sage", line 6: sage: blah+blah Out of tolerance 10000000000.0 vs 10000000100.0
So the error of "blah is undefined" is not printed, while the "out of tolerance" is printed for the wrong test.
- Also, there is a bug when a test with tolerance is the last test:
""" EXAMPLES: Doctests with tolerance cannot be followed by empty lines:: sage: 100+10000000000 # rel tol 0.1 10000000000 """
yields
File "/Users/marcostreng/.sage//tmp/test_71331.py", line 58 ... ''', res, 0.1, 're ^ SyntaxError: invalid syntax
- The following is documented to work, but actually doesn't work:
""" sage: 1e16 # relative tol 1e-10 10^16 """
Testing this gives
sage -t "/home/jdemeyer/doctest/tolerance_fail.py" ********************************************************************** File "/home/jdemeyer/doctest/tolerance_fail.py", line 2: sage: 1e16 # relative tol 1e-10 Expected ' 10^16 ' got '1.00000000000000e16' **********************************************************************

Issues 1 and 2 are fixed by #12415. Issue 3 might be "wontfix" but then the documentation needs to be changed.

Yes, and that is what the last block of changes of trac_13899-doctest-rebase.patch is for.

I consider this a feature, not a bug. If we're going to allow arithmetic expressions, where do we draw the line?
sage: 1e16 # rel tol 1e-10 100000000^2 sage: 1e16 # rel tol 1e-10 4e15 + 6e15 sage: 1e16 # rel tol 1e-10 solve(1e16 - x, x)[0].rhs()
There is also the advantage of being able to write
sage: "%g is less than %g" % (sqrt(2), pi) # rel tol .01 '1.41 is less than 3.14'
which is possible because we do a match on floating point literals.

+1 (for the reasons Robert mentions)
Jeroen, could appropriately change the documentation in trac_13899-doctest-rebase.patch?
comment:10 follow-up: ↓ 11 Changed 9 years ago by
I propose the following: we add a patch to this ticket to fix the documentation concerning issue 3 and close the first two issues as fixed by #12415.

A patch at #13899 documents the third bug in the ticket description.
