NAME
Test2::Tools::Subtest - Tools for writing subtests
DESCRIPTION
This package exports subs that let you write subtests.
There are two types of subtests, buffered and streamed. Streamed subtests mimic subtests
from Test::More in that they render all events as soon as they are produced. Buffered
subtests wait until the subtest completes before rendering any results.
The main difference is that streamed subtests are unreadable when combined with
concurrency. Buffered subtests look fine with any number of concurrent threads and
processes.
SYNOPSIS
BUFFERED
use Test2::Tools::Subtest qw/subtest_buffered/;
subtest_buffered my_test => sub {
ok(1, "subtest event A");
ok(1, "subtest event B");
};
This will produce output like this:
ok 1 - my_test {
ok 1 - subtest event A
ok 2 - subtest event B
1..2
}
STREAMED
The default option is 'buffered'. If you want streamed subtests, the way Test::Builder
does it, use this:
use Test2::Tools::Subtest qw/subtest_streamed/;
subtest_streamed my_test => sub {
ok(1, "subtest event A");
ok(1, "subtest event B");
};
This will produce output like this:
# Subtest: my_test
ok 1 - subtest event A
ok 2 - subtest event B
1..2
ok 1 - Subtest: my_test
IMPORTANT NOTE
You can use "bail_out" or "skip_all" in a subtest, but not in a BEGIN block or "use"
statement. This is due to the way flow control works within a BEGIN block. This is not
normally an issue, but can happen in rare conditions using eval, or script files as
subtests.
EXPORTS
subtest_streamed $name => $sub
subtest_streamed($name, $sub, @args)
subtest_streamed $name => \%params, $sub
subtest_streamed($name, \%params, $sub, @args)
Run subtest coderef, stream events as they happen.
"\%params" is a hashref with any arguments you wish to pass into hub construction.
subtest_buffered $name => $sub
subtest_buffered($name, $sub, @args)
subtest_buffered $name => \%params, $sub
subtest_buffered($name, \%params, $sub, @args)
Run subtest coderef, render events all at once when subtest is complete.
"\%params" is a hashref with any arguments you wish to pass into hub construction.
