NAME
Test::Builder::SubtestSelection - Select subtests by name or by number
SYNOPSIS
# content of t/basic.t test script
use strict; use warnings;
# create test builder singleton instance first
use Test::Builder::SubtestSelection;
# use test builder base framework
use Test::More tests => 2;
subtest 'this' => sub {
# this group of related test function calls
};
subtest 'or that' => sub {
# or that group of related test function calls
};DESCRIPTION
The Modern Perl blog entries referred to in the "SEE ALSO" section describe how usual Perl functions can be used to group related test function calls inside a test script. By convention the name of each such a grouping function should start with the test_ prefix. If the groups of test function calls are independent within the test script, which is anyway a good test discipline, it should be possible to run them individually. The Test::Named module supports this approach.
This Test::Builder::SubtestSelection class is a subclass of Test::Builder that overrides its subtest() method. It assumes that Test::Builder subtests are used to group related test function calls inside a test script. The class allows you to select subtests by name or by number to run them. The name of a subtest is more like a description. Any string is allowed and no special naming convention needs to be followed. If possible each string is treated as a regular expression; otherwise meta characters are properly quoted. The selection process itself applies to top-level (not nested) subtests only! The selection criteria (name or number) is the value of either the short -s or long --subtest option that have to be supplied together as arguments to the test script. To do so separate the arguments from prove's own arguments with the arisdottle (::). Example:
# run all subtests
prove -v -b t/basic.t
# run "this"
prove -v -b t/basic.t :: -s 1
# run "or that"
prove -v -b t/basic.t :: --subtest 'or that'SEE ALSO
