Weasel - Perl's php/Mink-inspired abstracted web-driver framework
=head1 VERSION
0.11
=head1 SYNOPSIS
use Weasel;
use Weasel::Session;
use Weasel::Driver::Selenium2;
my $weasel = Weasel->new(
default_session => 'default',
sessions => {
default => Weasel::Session->new(
driver => Weasel::Driver::Selenium2->new(%opts),
),
});
$weasel->session->get('http://localhost/index');
=head1 DESCRIPTION
This module abstracts away the differences between the various
web-driver protocols, like the Mink project does for PHP.
While heavily inspired by Mink, C<Weasel> aims to improve over it
by being extensible, providing not just access to the underlying
browser, yet to provide building blocks for further development
and abstraction.
L<Pherkin::Extension::Weasel> provides integration with
L<Test::BDD::Cucumber> (aka pherkin), for BDD testing.
For the actual page interaction, this module needs a driver to
be installed. Currently, that means L<Weasel::Driver::Selenium2>.
Other driver implementations, such as L<Sahi|http://sahipro.com/>
can be independently developed and uploaded to CPAN, or contributed.
(We welcome and encourage both!)
=head2 DIFFERENCES WITH OTHER FRAMEWORKS
=over
=item Mnemonics for element lookup patterns
The central registry of xpath expressions to find common page elements
helps to keep page access code clean. E.g. compare:
use Weasel::FindExpanders::HTML;
$session->page->find('*contains', text => 'Some text');
With
$session->page->find(".//*[contains(.,'Some text')]
[not(.//*[contains(.,'Some text')])]");
Multiple patterns can be registered for a single mnemonic, which
will be concatenated to a single xpath expression to find the matching
tags in a single driver query.
Besides good performance, this has the benefit that the following
$session->page->find('*button', text => 'Click!');
can be easily extended to match
L<Dojo toolkit's|http://dojotoolkit.org/documentation/> buttons, which
on the HTML level don't contain visible button or input tags, simply
by using the widget support set:
use Weasel::Widgets::Dojo;
=item Widgets encapsulate specific behaviours
All elements in C<Weasel> are of the base type C<Weasel::Element>, which
encapsulates the regular element interactions (click, find children, etc).
While most elements will be represented by C<Weasel::Element>, it's possible
to implement other wrappers. These offer a logical extension point to
implement tag-specific utility functions. E.g.
C<Weasel::Widgets::HTML::Select>, which adds the utility function
C<select_option>.
These widgets also offer a good way to override default behaviours. One
such case is the Dojo implementation of a 'select' element. This element
replaces the select tag entirely and in contrast with the original, doesn't
keep the options as child elements of the 'select'-replacing tag. By using
the Dojo widget library
use Weasel::Widget::Dojo;
the lack of the parent/child relation between the the select and its options
is transparently handled by overriding the widget's C<find> and C<find_all>
methods.
