NAME¶
Test::Class::Most - Test Classes the easy way
VERSION¶
Version 0.06
SYNOPSIS¶
Instead of this:
use strict;
use warnings;
use Test::Exception 0.88;
use Test::Differences 0.500;
use Test::Deep 0.106;
use Test::Warn 0.11;
use Test::More 0.88;
use parent 'My::Test::Class';
sub some_test : Tests { ... }
You type this:
use Test::Class::Most parent => 'My::Test::Class';
sub some_test : Tests { ... }
DESCRIPTION¶
When people write test classes with the excellent "Test::Class", you
often see the following at the top of the code:
package Some::Test::Class;
use strict;
use warnings;
use base 'My::Test::Class';
use Test::More;
use Test::Exception;
# and then the tests ...
That's a lot of boilerplate and I don't like boilerplate. So now you can do
this:
use Test::Class::Most parent => 'My::Test::Class';
That automatically imports strict and warnings for you. It also gives you all of
the testing goodness from Test::Most.
CREATING YOUR OWN BASE CLASS¶
You probably want to create your own base class for testing. To do this, simply
specify no import list:
package My::Test::Class;
use Test::Class::Most; # we now inherit from Test::Class
INIT { Test::Class->runtests }
1;
And then your other classes inherit as normal (well, the way we do it):
package Tests::For::Foo;
use Test::Class::Most parent => 'My::Test::Class';
And you can inherit from those other classes, too:
package Tests::For::Foo::Child;
use Test::Class::Most parent => 'Tests::For::Foo';
Of course, it's quite possible that you're a fan of multiple inheritance, so you
can do that, too (I was
soooooo tempted to not allow this, but I
figured I shouldn't force too many of my personal beliefs on you):
package Tests::For::ISuckAtOO;
use Test::Class::Most parent => [qw/
Tests::For::Foo
Tests::For::Bar
Some::Other::Class::For::Increased::Stupidity
/];
As a side note, it's recommended that even if you don't need test control
methods in your base class, put stubs in there:
package My::Test::Class;
use Test::Class::Most; # we now inherit from Test::Class
INIT { Test::Class->runtests }
sub startup : Tests(startup) {}
sub setup : Tests(setup) {}
sub teardown : Tests(teardown) {}
sub shutdown : Tests(shutdown) {}
1;
This allows developers to
always be able to safely call parent test
control methods rather than wonder if they are there:
package Tests::For::Customer;
use Test::Class::Most parent => 'My::Test::Class';
sub setup : Tests(setup) {
my $test = shift;
$test->next::method; # safe due to stub in base class
...
}
ATTRIBUTES¶
You can also specify "attributes" which are merely very simple
getter/setters.
use Test::Class::Most
parent => 'My::Test::Class',
attributes => [qw/customer items/],
is_abstract => 1;
sub setup : Tests(setup) {
my $test = shift;
$test->SUPER::setup;
$test->customer( ... );
$test->items( ... );
}
sub some_tests : Tests {
my $test = shift;
my $customer = $test->customer;
...
}
If called with no arguments, returns the current value. If called with one
argument, sets that argument as the current value. If called with more than
one argument, it croaks.
ABSTRACT CLASSES¶
You may pass an optional "is_abstract" parameter in the import list.
It takes a boolean value. This value is advisory only and is not inherited. It
defaults to false if not provided.
Sometimes you want to identify a test class as "abstract". It may have
a bunch of tests, but those should only run for its subclasses. You can pass
"<is_abstract =" 1>> in the import list. Then, to test if a
given class or instance of that class is "abstract":
sub dont_run_in_abstract_base_class : Tests {
my $test = shift;
return if Test::Class::Most->is_abstract($test);
...
}
Note that "is_abstract" is strictly
advisory only. You are
expected (required) to check the value yourself and take appropriate action.
We recommend adding the following method to your base class:
sub is_abstract {
my $test = shift;
return Test::Class::Most->is_abstract($test);
}
And later in a subclass:
if ( $test->is_abstract ) { ... }
EXPORT¶
All functions from Test::Most are automatically exported into your namespace.
