it is now possible to write .t tests in such a way that only selected
tests will be run. the .t's simply need to switch from using 'ok ...'
to 'sok { ... }'. where the argument to sok is a subroutine reference
who's return value will be passed to 'ok'. if subtests are specified
only those will be run/passed to ok, the rest will be skipped.
so for example, you can now do this:
modules/env....1..5
ok 1 # skip skipping this subtest
ok 2 # skip skipping this subtest
set: EXPECT ->mod_env test environment variable<- ACTUAL ->mod_env test
environment variable<-
ok 3
ok 4 # skip skipping this subtest
unset: EXPECT ->(none)<- ACTUAL ->(none)<-
ok 5
ok, 3/5 skipped: skipping this subtest
All tests successful.
