Problem: When a test is commented out we forget about it.
Solution: Let a test throw an exception with "Skipped" and list skipped test
functions. (Christian Brabandt)
Problem: When cancelling the :ptjump prompt a preview window is opened for
a following command.
Solution: Reset g_do_tagpreview. (Hirohito Higashi) Add a test. Avoid that
the test runner gets stuck in trying to close a window.
Problem: Using the system default encoding makes tests unpredictable.
Solution: Always use utf-8 or latin1 in the new style tests. Remove setting
encoding and scriptencoding where it is not needed.
Problem: The list_lbr_utf8 test fails if ~/.vim/syntax/c.vim sets
'textwidth' to a non-zero value. (Oyvind A. Holm)
Solution: Add a setup.vim file that sets 'runtimepath' and $HOME to a safe
value. (partly by Christian Brabandt, closes#912)
Problem: Using old function name in comment. More functions should start
with test_.
Solution: Rename function in comment. (Higashi Higashi) Rename
disable_char_avail_for_testing() to test_disable_char_avail().
And alloc_fail() to test_alloc_fail().
Problem: Cannot detect a crash in tests when caused by garbagecollect().
Solution: Add garbagecollect_for_testing(). Do not free a job if is still
useful.
Problem: Alloc_id depends on numbers, may use the same one twice. It's not
clear from the number what it's for.
Solution: Use an enum. Add a function to lookup the enum value from the
name.
Problem: New style tests are executed in arbitrary order.
Solution: Sort the test function names. (Hirohito Higashi)
Fix the quickfix test that depended on the order.
Problem: When a test script navigates to another buffer the .res file is
created with the wrong name.
Solution: Use the "testname" for the .res file. (Damien)
Problem: Writing tests for Vim script is hard.
Solution: Add assertEqual(), assertFalse() and assertTrue() functions. Add
the v:errors variable. Add the runtest script. Add a first new
style test script.
