sage -t --optional=... skips the normal tests?

[P Purkayastha]

I am trying to doctest the coding folder with the optional gap_packages. But it seems to skip the statements without the "# optional" statement. The result of it is that the optional tests are all failing. Here is an output:

...allations/sage-git [128] » sage -t --optional=gap_packages src/sage/coding

**********************************************************************

This shouldn't fail because 'Gstr' is defined all right in the actual file:

    EXAMPLES::


        sage: Gstr = "Z(2)*[[1,1,1,0,0,0,0], [1,0,0,1,1,0,0], [0,1,0,1,0,1,0], [1,1,0,1,0,0,1]]"
        sage: sage.coding.linear_code.min_wt_vec_gap(Gstr,7,4,GF(2))
        (0, 1, 0, 1, 0, 1, 0)


    This output is different but still a minimum weight vector::


        sage: sage.coding.linear_code.min_wt_vec_gap(Gstr,7,4,GF(2),algorithm="guava")    # optional - gap_packages (Guava package)
        (0, 0, 1, 0, 1, 1, 0)

Also, note that the files preceding "linear_code.py" all report "0 tests", which doesn't make any sense.

Is there some other argument I must provide with --optional?

sage -t --optional=sage,gap_packages src/sage/coding

Thanks. This worked.

I have been caught out by this one too. When you put the --optional
flag on the command line it *only* runs lines with that flag, where
the flag "sage" exceptionally means to run the other doctest lines
too, the ones with no flag. I think the idea is that the optional
tests should form complete sets in themselves, so that testing one of
the sets (e.g. gap_packages) can be done much faster than testing the
whole library.
