Selenium::Remote::Driver

Selenium WebDriver is a test tool that allows you to write automated web application UI tests in any programming language against any HTTP website using any mainstream JavaScript-enabled browser. This module is a Perl implementation of the client for the Webdriver JSONWireProtocol that Selenium provides.

Installation

It's probably easiest to use the cpanm or CPAN commands:

$ cpanm Selenium::Remote::Driver

If you want to install from this repository, see the installation docs for more details.

Usage

You can use this module to directly start the webdriver servers, after downloading the appropriate ones and putting the servers in your $PATH. This method does not require the JRE/JDK to be installed, nor does it require the standalone server jar, despite the name of the module. In this case, you'll want to use the appropriate class for driver construction: either Selenium::Chrome, Selenium::Firefox, Selenium::PhantomJS, or Selenium::InternetExplorer.

You can also use this module with the selenium-standalone-server.jar to let it handle browser start up for you, and also manage Remote connections where the server jar is not running on the same machine as your test script is executing. The main class for this method is Selenium::Remote::Driver.

Regardless of which method you use to construct your browser object, all of the classes use the functions listed in the S::R::Driver POD documentation, so interacting with the browser, the page, and its elements would be the same.

no standalone server

Firefox 48 & newer: install the Firefox browser, download geckodriver and put it in your $PATH. If the Firefox browser binary is not in the default place for your OS and we cannot locate it via which, you may have to specify the binary location during startup. We also will need to locate the Firefox browser; if the Firefox browser isn't in the default location, you must provide it during startup in the firefox_binary attr.
Firefox 47 & older: install the Firefox browser in the default place for your OS. If the Firefox browser binary is not in the default place for your OS, you may have to specify the firefox_binary constructor option during startup.
Chrome: install the Chrome browser, download Chromedriver and get chromedriver in your $PATH.
PhantomJS: install the PhantomJS binary and get phantomjs in your $PATH. The driver for PhantomJS, Ghostdriver, is bundled with PhantomJS.

When the browser(s) are installed and you have the appropriate binary in your path, you should be able to do the following:

my $firefox = Selenium::Firefox->new;
$firefox->get('http://www.google.com');

my $chrome = Selenium::Chrome->new;
$chrome->get('http://www.google.com');

my $ghost = Selenium::PhantomJS->new;
$ghost->get('http://www.google.com');

Note that you can also pass a binary argument to any of the above classes to manually specify what binary to start. Note that this binary refers to the driver server, not the browser executable.

my $chrome = Selenium::Chrome->new(binary => '~/Downloads/chromedriver');

See the pod for the different modules for more details.

Breaking Changes for Selenium::Firefox in v1.0+

There are breaking changes for Selenium::Firefox from v0.2701 of S:F to v1.0+. This is because in FF47 and older, Firefox didn't have a separate webdriver server executable - local startup was accomplished by starting your actual Firefox browser with a webdriver extension. However, in FF48 and newer, Mozilla have switched to using geckodriver to handle the Webdriver communication. Accordingly, v1.0+ of Selenium::Firefox assumes the geckodriver setup which only works for FF48 and higher:

# marionette_enabled defaults to 1 === assumes you're running FF48
my $fx48 = Selenium::Firefox->new;
my $fx48 = Selenium::Firefox->new( marionette_enabled => 1 );

To drive FF47 with v1.0+ of Selenium::Firefox, you must manually disable marionette:

my $fx47 = Selenium::Firefox->new( marionette_enabled => 0 );

Doing so will start up your Firefox browser with the webdriver extension. Note that in our tests, doing the old "webdriver-extension-startup" for Firefox 48 does not work. Likewise, geckodriver does not work with FF47.

with a standalone server

Download the standalone server and have it running on port 4444:

$ java -jar selenium-server-standalone-X.XX.X.jar

As before, have the browsers themselves installed on your machine, and download the appropriate binary server, passing its location to the server jar during startup.

Locally

use strict;
use warnings;
use Selenium::Remote::Driver;

my $driver = Selenium::Remote::Driver->new;
$driver->get('http://www.google.com');
print $driver->get_title . "\n"; # "Google"

my $query = $driver->find_element('q', 'name');
$query->send_keys('CPAN Selenium Remote Driver');

my $send_search = $driver->find_element('btnG', 'name');
$send_search->click;

# make the find_element blocking for a second to allow the title to change
$driver->set_implicit_wait_timeout(2000);
my $results = $driver->find_element('search', 'id');

print $driver->get_title . "\n"; # CPAN Selenium Remote Driver - Google Search
$driver->quit;

Saucelabs

If using Saucelabs, there's no need to have the standalone server running on a local port, since Saucelabs provides it.

use Selenium::Remote::Driver;

my $user = $ENV{SAUCE_USERNAME};
my $key = $ENV{SAUCE_ACCESS_KEY};

my $driver = Selenium::Remote::Driver->new(
    remote_server_addr => $user . ':' . $key . '@ondemand.saucelabs.com',
    port => 80
);

$driver->get('http://www.google.com');
print $driver->get_title();
$driver->quit();

There are additional usage examples on metacpan, and also in this project's wiki, including setting up the standalone server, running tests on Internet Explorer, Chrome, PhantomJS, and other useful example snippets.

Selenium IDE Plugin

ide-plugin.js is a Selenium IDE Plugin which allows you to export tests recorded in Selenium IDE to a perl script.

Installation in Selenium IDE

Open Selenium IDE
Options >> Options
Formats Tab
Click Add at the bottom
In the name field call it 'Perl-Webdriver'
Paste this entire source in the main textbox
Click 'Save'
Click 'Ok'
Close Selenium IDE and open it again.

Note: The Code generated by this plugin currently assumes that you have firefox 48 or newer + the geckodriver plugin installed.

If you have an older version of firefox you can adjust the plugin the following way: In the options window of selenium IDE (Formats tab) there is a input box called "Header". Here you can modify the fixed header code beeing generatd. Change Selenium::Firefox->new(); according to the firefox init examples shown above in this README.

Support and Documentation

There is a mailing list available at

https://groups.google.com/forum/#!forum/selenium-remote-driver

for usage questions and ensuing discussions. If you've come across a bug, please open an issue in the Github issue tracker. The POD is available in the usual places, including metacpan, and in your shell via perldoc.
