Greetings Avout, I'm attempting to use TAP::Harness to test CFEngine policy and I'm having trouble creating the final test commands. The following code is supposed to check the TAP output for these two commands:

/usr/bin/cf-agent -D efl_returnszero_csv -Kf ./promises.cf
/usr/bin/cf-agent -D efl_returnszero_json -Kf ./promises.cf
[download]

The -f switch must have the ./promises.cf argument. When I run prove t/efl_returnszero.t I get this error:

t/efl_returnszero.t .. No subtests run 

Test Summary Report
-------------------
t/efl_returnszero.t (Wstat: 0 Tests: 0 Failed: 0)
  Parse errors: No plan found in TAP output
Files=1, Tests=0,  2 wallclock secs ( 0.03 usr  0.00 sys +  1.54 cusr 
+ 0.04 csys =  1.61 CPU)
Result: FAIL

My guess is that the final commands are coming out in a scrambled order resulting in no output, but how can I test that?

#!/usr/bin/perl

use strict;
use warnings;
use Carp;
use TAP::Harness;

chdir 'test/masterfiles' or croak "Cannot cd to test/masterfiles $!";

my @tests = (
   [ './promises.cf', 'using_csv' ],
   [ './promises.cf', 'using_json' ],
);

# Final test command is exec + element from test + arg?
my $harness = TAP::Harness->new({
      exec      => [ qw( /usr/bin/cf-agent -Kf ) ],
      test_args => {
         using_csv  => [ '-D efl_returnszero_csv' ],
         using_json => [ '-D efl_returnszero_json' ],
      },
      verbosity => 1,
      errors => 1,
      show_count => 1,
});

$harness->runtests( @tests );

UPDATE: turns out the test args cannot have white space so

   test_args => {
      using_csv  => [ '-D efl_returnszero_csv' ],
      using_json => [ '-D efl_returnszero_json' ],
   },
   # Must be:
   test_args => {
      using_csv  => [ '-D', 'efl_returnszero_csv' ],
      using_json => [ '-D', 'efl_returnszero_json' ],
   },
