=head1 NAME
Selenium::Remote::Driver - Perl Client for Selenium Remote Driver
=head1 VERSION
version 0.2102
=head1 SYNOPSIS
use Selenium::Remote::Driver;
my $driver = Selenium::Remote::Driver->new;
$driver->get('http://www.google.com');
print $driver->get_title();
$driver->quit();
=head1 DESCRIPTION
Selenium 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
an implementation of the client for the Remote driver that Selenium provides.
You can find bindings for other languages at this location:
L<http://code.google.com/p/selenium/>
This module sends commands directly to the Server using HTTP. Using this module
together with the Selenium Server, you can automatically control any supported
browser. To use this module, you need to have already downloaded and started
the Selenium Server (Selenium Server is a Java application).
=head1 USAGE (read this first)
=head2 Remote Driver Response
Selenium::Remote::Driver uses the L<JsonWireProtocol|http://code.google.com/p/selenium/wiki/JsonWireProtocol> to communicate with the
Selenium Server. If an error occurs while executing the command then the server
sends back an HTTP error code with a JSON encoded reponse that indicates the
precise L<Response Error Code|http://code.google.com/p/selenium/wiki/JsonWireProtocol#Response_Status_Codes>. The module will then croak with the error message
associated with this code. If no error occurred, then the subroutine called will
return the value sent back from the server (if a return value was sent).
So a rule of thumb while invoking methods on the driver is if the method did not
croak when called, then you can safely assume the command was successful even if
nothing was returned by the method.
=head2 WebElement
Selenium Webdriver represents all the HTML elements as WebElement, which is
in turn represented by L<Selenium::Remote::WebElement> module. So any method that
deals with WebElements will return and/or expect WebElement object. The POD for
that module describes all the methods that perform various actions on the
WebElements like click, submit etc.
To interact with any WebElement you have to first "find" it, read the POD for
find_element or find_elements for further info. Once you find the required element
then you can perform various actions. If you don't call find_* method first, all
your further actions will fail for that element. Finally, just remember that you
don't have to instantiate WebElement objects at all - they will be automatically
created when you use the find_* methods.
A sub-class of Selenium::Remote::WebElement may be used instead of Selenium::Remote::WebElement,
by providing that class name as an option the constructor:
my $driver = Selenium::Remote::Driver->new( webelement_class => ... );
For example, a testing-subclass may extend the web-element object with testing methods.
=head1 TESTING
If are writing automated tests using this module, make sure you also see
L<Test::Selenium::Remote::Driver> which is also included in this distribution.
It includes convenience testing methods for many of the selenum methods
available here.
=head1 FUNCTIONS
=head2 new
Description:
Constructor for Driver. It'll instantiate the object if it can communicate
with the Selenium Webdriver server.
Input: (all optional)
Desired capabilities - HASH - Following options are accepted:
Optional:
'remote_server_addr' - <string> - IP or FQDN of the Webdriver server machine
'port' - <string> - Port on which the Webdriver server is listening
'browser_name' - <string> - desired browser string: {phantomjs|firefox|internet explorer|htmlunit|iphone|chrome}
'version' - <string> - desired browser version number
'platform' - <string> - desired platform: {WINDOWS|XP|VISTA|MAC|LINUX|UNIX|ANY}
'javascript' - <boolean> - whether javascript should be supported
'accept_ssl_certs' - <boolean> - whether SSL certs should be accepted, default is true.
'firefox_profile' - Profile - Use S::R::D::Firefox::Profile to create a Firefox profile for the browser to use
'proxy' - HASH - Proxy configuration with the following keys:
'proxyType' - <string> - REQUIRED, Possible values are:
direct - A direct connection - no proxy in use,
manual - Manual proxy settings configured, e.g. setting a proxy for HTTP, a proxy for FTP, etc,
pac - Proxy autoconfiguration from a URL,
autodetect - proxy autodetection, probably with WPAD,
system - Use system settings
'proxyAutoconfigUrl' - <string> - REQUIRED if proxyType is 'pac', ignored otherwise. Expected format: http://hostname.com:1234/pacfile.
'ftpProxy' - <string> - OPTIONAL, ignored if proxyType is not 'manual'. Expected format: hostname.com:1234
'httpProxy' - <string> - OPTIONAL, ignored if proxyType is not 'manual'. Expected format: hostname.com:1234
'sslProxy' - <string> - OPTIONAL, ignored if proxyType is not 'manual'. Expected format: hostname.com:1234
'extra_capabilities' - HASH - Any other extra capabilities
You can also specify some options in the constructor hash that are
not part of the browser-related desired capabilities. These items
are also optional.
'auto_close' - <boolean> - whether driver should end session on remote server on close.
'base_url' - <string> - OPTIONAL, base url for the website Selenium acts on. This can save you from repeating the domain in every call to $driver->get()
'default_finder' - <string> - choose default finder used for find_element* {class|class_name|css|id|link|link_text|name|partial_link_text|tag_name|xpath}
'inner_window_size' - <aref[Int]>- An array ref [ height, width ] that the browser window should use as its initial size immediately after instantiation
'webelement_class' - <string> - sub-class of Selenium::Remote::WebElement if you wish to use an alternate WebElement class.
'ua' - LWP::UserAgent instance - if you wish to use a specific $ua, like from Test::LWP::UserAgent
If no values are provided, then these defaults will be assumed:
'remote_server_addr' => 'localhost'
'port' => '4444'
'browser_name' => 'firefox'
'version' => ''
'platform' => 'ANY'
'javascript' => 1
'auto_close' => 1
'default_finder' => 'xpath'
Output:
Remote Driver object
Usage:
my $driver = Selenium::Remote::Driver->new;
or
my $driver = Selenium::Remote::Driver->new('browser_name' => 'firefox',
'platform' => 'MAC');
or
my $driver = Selenium::Remote::Driver->new('remote_server_addr' => '10.10.1.1',
'port' => '2222',
'auto_close' => 0);
or
my $driver = Selenium::Remote::Driver->new('browser_name' =>'chrome'
'extra_capabilities' => {
'chromeOptions' => {
'args' => [
'window-size=1260,960',
'incognito'
],
'prefs' => {
'session' => {
'restore_on_startup' => 4,
'urls_to_restore_on_startup' => [
'http://www.google.com',
'http://docs.seleniumhq.org'
]},
'first_run_tabs' => [
'http://www.google.com',
'http://docs.seleniumhq.org'
]
}
}
});
or
my $driver = Selenium::Remote::Driver->new('proxy' => {'proxyType' => 'manual', 'httpProxy' => 'myproxy.com:1234'});
or
my $driver = Selenium::Remote::Driver->new('default_finder' => 'css');
=head2 new_from_caps
Description:
For experienced users who want complete control over the desired
capabilities, use this alternative constructor along with the
C<desired_capabilities> hash key in the init hash. Unlike "new",
this constructor will not assume any defaults for your desired
capabilities.
This alternate constructor IGNORES all other browser-related
desiredCapability options; the only options that will be respected
are those that are NOT part of the Capabilities JSON Object as
described in the Json Wire Protocol.
Input:
The only respected keys in the input hash are:
desired_capabilities - HASHREF - defaults to {}
remote_server_addr - STRING - defaults to localhost
port - INTEGER - defaults to 4444
default_finder - STRING - defaults to xpath
webelement_class - STRING - defaults to Selenium::Remote::WebElement
auto_close - BOOLEAN - defaults to 1
Except for C<desired_capabilities>, these keys perform exactly the
same as listed in the regular "new" constructor.
The hashref you pass in as desired_capabilities only gets json
encoded before being passed to the Selenium server; no default
options of any sort will be added.
This means you must handle normalization and casing of the input
options (like "browser_name" vs "browserName") and take care of
things like encoding the firefox profile if applicable. More
information about the desired capabilities object is available on
the Selenium wiki:
https://code.google.com/p/selenium/wiki/JsonWireProtocol#Capabilities_JSON_Object
Output:
Remote Driver object
Usage:
my $driver = Selenium::Remote::Driver->new_from_caps(
'desired_capabilities' => {'browserName' => 'firefox'}
);
The above would generate a POST to the webdriver server at
localhost:4444 with the exact payload of '{"desiredCapabilities":
{"browserName": "firefox" }}'.
=head2 debug_on
Description:
Turns on debugging mode and the driver will print extra info like request
and response to stdout. Useful, when you want to see what is being sent to
the server & what response you are getting back.

$driver->debug_on;
=head2 debug_off
Description:
Turns off the debugging mode.
Usage:
$driver->debug_off;
=head2 get_sessions
Description:

returned as an array of Hashes with the following keys:
'id' : The session ID
'capabilities: An object describing session's capabilities
Output:
Array of Hashes
Usage:
print Dumper $driver->get_sessions();
=head2 status

=head2 send_keys_to_active_element
Description:
Send a sequence of key strokes to the active element. This command is
similar to the send keys command in every aspect except the implicit
termination: The modifiers are not released at the end of the call.
Rather, the state of the modifier keys is kept between calls, so mouse
interactions can be performed while modifier keys are depressed.
Input: 1
Required:
{ARRAY | STRING} - Array of strings or a string.
Usage:
$driver->send_keys_to_active_element('abcd', 'efg');
$driver->send_keys_to_active_element('hijk');
or
# include the WDKeys module
use Selenium::Remote::WDKeys;
.
.
$driver->send_keys_to_active_element(KEYS->{'space'}, KEYS->{'enter'});

Accepts the currently displayed alert dialog. Usually, this is
equivalent to clicking the 'OK' button in the dialog.
Example:
$driver->accept_alert;
=head2 dismiss_alert
Description:

=head2 mouse_move_to_location
Description:
Move the mouse by an offset of the specificed element. If no
element is specified, the move is relative to the current mouse
cursor. If an element is provided but no offset, the mouse will be
moved to the center of the element. If the element is not visible,
it will be scrolled into view.
Output:
STRING -
Usage:
# element - the element to move to. If not specified or is null, the offset is relative to current position of the mouse.
# xoffset - X offset to move to, relative to the top-left corner of the element. If not specified, the mouse will move to the middle of the element.
# yoffset - Y offset to move to, relative to the top-left corner of the element. If not specified, the mouse will move to the middle of the element.
