Return a String that is null. Only useful for testing.
test_option_not_set({name}) *test_option_not_set()*
Reset the flag that indicates option {name} was set. Thus it
looks like it still has the default value. Use like this: >
set ambiwidth=double
call test_option_not_set('ambiwidth')
< Now the 'ambiwidth' option behaves like it was never changed,
even though the value is "double".
Only to be used for testing!
test_override({name}, {val}) *test_override()*
Overrides certain parts of Vims internal processing to be able
to run tests. Only to be used for testing Vim!
