Yeah, we could do something along these lines:

andrew(at)emma:pg_head $ cat moduletest.pl
use IPC::Run 0.79;
use Test::More 0.98;
use Time::HiRes 1.52;
diag("");
diag("Test::More::VERSION: $Test::More::VERSION");
diag("IPC::Run::VERSION: $IPC::Run::VERSION");
diag("Tme::HiRes::VERSION: $Time::HiRes::VERSION");
ok(1);
done_testing();
andrew(at)emma:pg_head $ prove moduletest.pl
moduletest.pl .. #
# Test::More::VERSION: 1.302183
# IPC::Run::VERSION: 20200505.0
# Tme::HiRes::VERSION: 1.9764
moduletest.pl .. ok
All tests successful.
Files=1, Tests=1, 0 wallclock secs ( 0.04 usr 0.01 sys + 0.13 cusr 0.02 csys = 0.20 CPU)
Result: PASS

If I hack up the test to fail I get:

andrew(at)emma:pg_head $ prove moduletest.pl
moduletest.pl .. Test::More version 9.98 required--this is only version 1.302183 at moduletest.pl line 2.
BEGIN failed--compilation aborted at moduletest.pl line 2.
moduletest.pl .. Dubious, test returned 255 (wstat 65280, 0xff00)
No subtests run

which is clear enough.

prove is pretty much always a script - if we want to know which perl is
invoked we could look at its shebang line.

cheers
