Steps to reproduce the problem:
$ LANG=POSIX ./run unit/_parse_help.exp
...
Running ./unit/_parse_help.exp ...
FAIL: short + long
FAIL: short + long, slash separated
Cause:
When comparing list items, `assert_bash_list()' expects the real list to be
sorted, whereas the output of `_parse_help' is unsorted.
These particular two tests were failing because they suffered the
following LANG-dependant sort-difference:
$ cat t.txt
-m
--n
$ LANG=en_US.UTF-8 sort t.txt
-m
--n
$ LANG=POSIX sort t.txt
--n
-m
Solution:
Made to default for `assert_bash_list' more-intuitive: unsorted, and added an
option `-sort' to explicitly enable sorting.
I felt uncomfortable adding yet another optional argument, so I seized this
opportunity to move subsequent optional arguments to single optional arguments.
E.g.:
assert_bash_list {expected cmd {test ""} {prompt /@} {size 20}} {
has now become:
# ...
# @param list $args Options:
# -nosort Compare list unsorted. Default is sorted
# -prompt Bash prompt. Default is `/@'
# -chunk-size N Compare list N items at a time. Default
# is 20.
assert_bash_list {expected cmd test {args {}}
(and the `test' argument has become mandatory).
