Test::Aggregate::Nested - Aggregate *.t tests to make them run faster.


Version 0.375


    use Test::Aggregate::Nested;

    my $tests = Test::Aggregate::Nested->new( {
        dirs    => $aggregate_test_dir,
        verbose => 1,
    } );


ALPHA WARNING: this is alpha code. Conceptually it is superior to Test::Aggregate, but in reality, it might not be. We'll see.

This module is almost identical to Test::Aggregate and will in the future be the preferred way of aggregating tests (until someone comes up with something better :)

Test::Aggregate::Nested requires a 0.8901 or better of Test::More. This is because we use its subtest function. Currently we croak if this function is not available.

Because the TAP output is nested, you'll find it much easier to see which tests result in which output. For example, consider the following snippet of TAP.

        ok 1 - aggtests/check_plan.t ***** 1
        ok 2 - aggtests/check_plan.t ***** 2
        ok 3 # skip checking plan (aggtests/check_plan.t ***** 3)
        ok 4 - env variables should not hang around
        ok 5 - aggtests/check_plan.t ***** 4
    ok 1 - Tests for aggtests/check_plan.t
        ok 1 - subs work!
    ok 2 - Tests for aggtests/subs.t

At the end of each nested test is a summary test line explaining which program we ran tests for.

Test::Aggregate::Nested asserts a plan equal to the number of test files aggregated, something which Test::Aggregate could not do. Because of this, we no longer export Test::More functions. If you need additional tests before or after aggregation, you can run the aggregated tests in a subtest:

    use Test::More tests => 2;
    use Test::Aggregate::Nested;

    subtest 'Nested tests' => sub {
        Test::Aggregate::Nested->new({ dirs => 'aggtests/' })->run;
    ok $some_other_test;

or disable the generation of the plan with the parameter no_generate_plan:

    use Test::More;
    use Test::Aggregate::Nested;

    Test::Aggregate::Nested->new({ dirs => 'aggtests/', no_generate_plan => 1 })->run;
    ok $some_other_test;


Test::Aggregate::Nested is much cleaner than Test::Aggregate, so I don't support the dump argument. If this is needed, let me know and I'll see about fixing this.

The "variable will not stay shared" warnings from Test::Aggregate (see its CAVEATS section) are no longer applicable.
