NAME
Test2::Roo::Role - Composable role for Test2::Roo
VERSION
version 1.005
SYNOPSIS
A testing role:
# t/lib/MyTestRole.pm
package MyTestRole;
use Test2::Roo::Role; # loads Moo::Role and Test2::V0
requires 'class';
test 'object creation' => sub {
my $self = shift;
require_ok( $self->class );
my $obj = new_ok( $self->class );
};
1;DESCRIPTION
This module defines test behaviors as a Moo::Role.
USAGE
Importing Test2::Roo::Role also loads Moo::Role (which gives you strictures with fatal warnings and other goodies).
Importing also loads Test2::V0. Any import arguments are passed through to Test2::V0's import method.
Creating and requiring fixtures
You can create fixtures with normal Moo syntax. You can even make them lazy if you want and require the composing class to provide the builder:
has fixture => (
is => 'lazy'
);
requires '_build_fixture';Because this is a Moo::Role, you can require any method you like, not just builders.
See Moo::Role and Role::Tiny for everything you can do with roles.
Setup and teardown
You can add method modifiers around the setup and teardown methods and these will be run before tests begin and after tests finish (respectively).
before setup => sub { ... };
after teardown => sub { ... };You can also add method modifiers around each_test, which will be run before and after every individual test. You could use these to prepare or reset a fixture.
has fixture => ( is => 'lazy, clearer => 1, predicate => 1 );
after each_test => sub { shift->clear_fixture };Roles may also modify setup, teardown, and each_test, so the order that modifiers will be called will depend on when roles are composed. Be careful with each_test, though, because the global effect may make composition more fragile.
You can call test functions in modifiers. For example, you could confirm that something has been set up or cleaned up.
before each_test => sub { ok( ! shift->has_fixture ) };EXPORTED FUNCTIONS
Loading Test2::Roo::Role exports a single subroutine into the calling package to declare tests.
test
test $label => sub { ... };The test function adds a subtest. The code reference will be called with the test object as its only argument.
Tests are run in the order declared, so the order of tests from roles will depend on when they are composed relative to other test declarations.
