NAME
Weasel - Perl's php/Mink-inspired abstracted web-driver framework
VERSION
0.31
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');
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, 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.
Pherkin::Extension::Weasel provides integration with Test::BDD::Cucumber (aka pherkin), for BDD testing.
For the actual page interaction, this module needs a driver to be installed. Currently, that means Weasel::Driver::Selenium2. Other driver implementations, such as Sahi can be independently developed and uploaded to CPAN, or contributed. (We welcome and encourage both!)
DIFFERENCES WITH OTHER FRAMEWORKS
- 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
$session->page->find('*button', text => 'Click!');
can be easily extended to match Dojo toolkit's buttons, which on the HTML level don't contain visible button or input tags, simply by using the widget support set:
use Weasel::Widgets::Dojo;
- Widgets encapsulate specific behaviours
-
All elements in
Weasel
are of the base typeWeasel::Element
, which encapsulates the regular element interactions (click, find children, etc).While most elements will be represented by
Weasel::Element
, it's possible to implement other wrappers. These offer a logical extension point to implement tag-specific utility functions. E.g.Weasel::Widgets::HTML::Select
, which adds the utility functionselect_option
.These widgets also offer a good way to override default behaviours. One such case is the Dojo implementation of a 'select' element. This element replaces the select tag entirely and in contrast with the original, doesn't keep the options as child elements of the 'select'-replacing tag. By using the Dojo widget library
use Weasel::Widget::Dojo;
the lack of the parent/child relation between the the select and its options is transparently handled by overriding the widget's
find
andfind_all
methods.
DEPENDENCIES
- KEYS
-
Returns a reference to a hash with names of the keys in the hash keys and single-character strings containing the key codes as the values.
ATTRIBUTES
- default_session
-
The name of the default session to return from
session
, in case no name argument is provided. - sessions
-
Holds the sessions registered with the
Weasel
instance.
SUBROUTINES/METHODS
- session([$name [, $value]])
-
Returns the session identified by
$name
.If
$value
is specified, it's associated with the given$name
.
