I read from TestCase.pm POD that one can populate @TESTS array in order to specify the desired order of tests execution:
Ah, I started at the bottom of my inbox and worked back... why does it matter what order the tests run? The xUnit idea is that each test (and its associated setup/teardown) should stand alone.
Suppose that one test is for database INSERT statement, and the other -- for SELECT, and that last -- for DELETE. That way I need to maintain the order of tests execution. Of course, I can put all operations into one test instead.

If you need to specify the test order, you can do one of the following:
=over 4
=item * Set @TESTS
our @TESTS = qw(my_test my_test_2);
This is the simplest, and recommended way.

But the above does not work for me. I can include only desired tests using @TESTS, but they are listed and executed in a random order,
Hmm, that comment seems to be out of date. @TESTS is piled into a hash, then the keys are listed as you said.
Aha.. That is the clue! Thanks. I should study sources myself :)
I decided to override list_tests method like this:
sub list_tests { my $self = shift; return sort $self->SUPER::list_tests(@_); }
That would do it, yes. Did you see in Test/Unit/TestCase.pm,
# Returns a list of the tests run by this class and its superclasses. # DO NOT OVERRIDE THIS UNLESS YOU KNOW WHAT YOU ARE DOING! sub list_tests { ...
Maybe that comment could be more helpful... 8-/
It works as expected. What do you think? Am I missing something?
Well it could be that you are missing something. If you try to avoid using side effects from each test, then the order should not matter.
I suppose one day the tests may be run in parallel. That would be neat, and it would also be incompatible with explicit test ordering.
Hmm.. Never thought about parallel execution.. Indeed it may be a godd idea.
