WebDriver2

WebDriver level 2 bindings implementing W3C's specification. Current implementation status is documented below.

Usage

Using a driver directly

To use a driver directly for all endpoint commands, create a test class that does WebDriver2::Test::Template. The test class will need to specify the browser upon instantiation:

use Test;
use WebDriver2::Test::Template;
use WebDriver2::SUT::Tree;

# can be file path or web address
my WebDriver2::SUT::Tree::URL:D $page =
		WebDriver2::SUT::Tree::URL.new: 'file://xt/content/test.html';

class Local does WebDriver2::Test::Template {
	has Bool $!screenshot;
	
	has Int:D $.plan = 38;
	has Str:D $.name = 'local';
	has Str:D $.description = 'local test';

	# WebDriver2::Test::Template provides method new, which
	#   sets the browser / loads from file if not passed
	#   and instantiates the corresponding driver
	
	method test {
		$.driver.navigate: $page.Str;
		
		is $.driver.title, 'test', 'page title';
		
		ok
				self.element-by-id( 'outer' ) ~~ self.element-by-tag( 'ul' ),
				'same element found different ways';
		
		my WebDriver2::Command::Element::Locator $by-tag-ul =
				WebDriver2::Command::Element::Locator::Tag-Name.new: 'ul';
		my WebDriver2::Model::Element $el = $.driver.element: $by-tag-ul;
		nok $el ~~ $el.element( $by-tag-ul ), 'different elements';
		
		my WebDriver2::Command::Element::Locator $locator =
				WebDriver2::Command::Element::Locator::Tag-Name.new: 'li';
		$el = $.driver.element: $locator;
		my Str $outer-li = $el.text;
		my Str $inner-li =
				self.element-by-id( 'inner' ).element( $locator ).text;
		
		isnt $inner-li, $outer-li, 'inner li != outer li';
		
		# test continues ...
	}
}

sub MAIN (
	Str $browser?,
	Int:D :$debug = 0
) {
	.execute with Local.new: $browser, :$debug;
}

WebDriver2::Test::Template calls

method init { ... }
method pre-test { ... }
method test { ... }
method post-test { ... }
method close { ... }
method done-testing { done-testing }
method cleanup { ... }

when its execute method is called.

Before starting into the test code, $.driver.session needs to be called, along with $.driver.delete-session after test code has completed. These two calls are made automatically during init and close when doing the provided role WebDriver2::Test::Template.

Defining a site's pages and the services they provide

A simple page description language is defined in the page grammar file.

For a multi-page site, e.g., with a login page and a main page with an iframe, in addition to the html files, a "system under test" definition, which could optionally be split into multiple .page files, and .service definitions are needed.

For example, for

doc-site.sut

#include 'doc-login.page'
#include 'doc-main.page'

doc-login.html

<html>
	<head><title>start page</title></head>
	<body>
		<form action="doc-main.html">
			<input type="text" id="user" name="user"/>
			<input type="text" id="pass" name="pass"/>
			<button name="k" value="v">log in</button>
		</form>
	</body>
</html>

doc-login.page

page doc-login 'file://relative/path/to/doc-login.html' {
	elemt username id 'user';
	elemt password id 'pass';
	elemt login-button tag-name 'button';
}

doc-login.service

#page: doc-login

username: /username
password: /password
login-button: /login-button

doc-main.html

<html>
	<head><title>simple example</title></head>
	<body>
		<h1>simple example</h1>
		<p id="before">text</p>
		<form><input type="text" value="main-1"/></form>
		<iframe src="doc-frame.html"></iframe>
		<form><input type="text" value="main-2"/></form>
		<p>other content</p>
		<form><input type="text" value="main-3"/></form>
		<form><input type="text" value="main-4"/></form>
		<p id="after">more text</p>
	</body>
</html>

doc-main.page - with only content we're interested in outlined

page doc-main 'file://relative/path/to/doc-main.html' {
	elemt heading tag-name 'h1';
	elemt first-para id 'before';
#include 'doc-frame.page'
list of
#include 'doc-form.page'
	elemt last-para id 'after';
}

doc-main.service

#page: doc-main

heading: /heading
pf: /first-para
iframe: /iframe
form: /form
pl: /last-para

doc-frame.html

<html>
	<head><title>iframe</title></head>
	<body>
		<form><input type="text" value="head"/></form>
		<ul>
			<li>
				<ol>
					<li>Mirzakhani</li>
					<li>Noether</li>
					<li>Oh</li>
				</ol>
			</li>
			<li>
				<ol>
					<li>Delta</li>
					<li>Echo</li>
					<li>Foxtrot</li>
				</ol>
			</li>
			<li>
				<ol>
					<li>apple</li>
					<li>banana</li>
					<li>cantaloupe</li>
				</ol>
			</li>
		</ul>
		<div><form><input type="text" value="foot"/></form></div>
	</body>
</html>

doc-frame.page - again, only content we're interested in is outlined

frame iframe tag-name 'iframe' {
#include 'doc-form.page'
	list of elgrp outer xpath '*/ul/li' {
		list of elemt inner xpath 'ol/li';
	}
	elgrp div tag-name 'div' {
#include 'doc-form.page'
	}
}

doc-frame.service

#page: doc-main

iframe: /iframe

outer: /iframe/outer
inner: /iframe/outer/inner

if identical content exists in multiple parts of the SUT ( e.g., calendar widgets ), it can be defined once and included in those parts by specifying a prefix

doc-form.page

elgrp form xpath 'form' {
	elemt input tag-name 'input';
}

doc-form.service

#page: doc-main

form: /form
input: /form/input

Extended examples can be seen in the xt/02-driver (direct driver use) and the xt/03-service (page definition and service use) subdirectories, which use resources from xt/content and xt/def.

HTTP::UserAgent

A minor fork of HTTP::UserAgent is provided under the WebDriver2 directory. Please see its license: LICENSE-HTTP-UserAgent.

The changes are:

fix content length (geckodriver does not gracefully handle incorrect content lengths)
increase amount of info logged (originally capped at 300 characters per entry)

TODO

cover all implemented endpoints with unit tests
add POD
implement the rest of the endpoints
page and service object features

Feedback

Suggestions, design recommendations, and feature requests welcome.
