38 |
|
|
|
39 |
root |
1.39 |
This module aims to implement the L<W3C |
40 |
|
|
WebDriver|https://www.w3.org/TR/webdriver1/> specification which is the |
41 |
root |
1.38 |
standardised equivalent to the Selenium WebDriver API, which in turn aims |
42 |
root |
1.1 |
at remotely controlling web browsers such as Firefox or Chromium. |
43 |
|
|
|
44 |
root |
1.30 |
One of the design goals of this module was to stay very close to the |
45 |
|
|
language and words used in the WebDriver specification itself, so to make |
46 |
|
|
most of this module, or, in fact, to make any reasonable use of this |
47 |
|
|
module, you would need to refer to the W3C WebDriver recommendation, which |
48 |
|
|
can be found L<here|https://www.w3.org/TR/webdriver1/>: |

Mozilla's C<geckodriver> has had webdriver support for a long time, while |
53 |
root |
1.41 |
C<chromedriver> only has basic and mostly undocumented webdriver support |
54 |
root |
1.46 |
as of release 77. |
55 |
root |
1.41 |
|
56 |
root |
1.54 |
In Debian GNU/Linux, you can install the chromedriver for chromium |
57 |
|
|
via the C<chromium-driver> package. Unfortunately, there is no |
58 |
|
|
(working) package for geckodriver, but you can download it from |
59 |
|
|
L<github|https://github.com/mozilla/geckodriver/releases>. |

62 |
|
|
|
63 |
|
|
Unless otherwise stated, all delays and time differences in this module |
64 |
root |
1.55 |
are represented as an integer number of milliseconds, which is perhaps |
65 |
|
|
surprising to users of my other modules but is what the WebDriver spec |
66 |
|
|
uses. |

|
|
187 |
|

=item endpoint => $string |
188 |
|
|
|
189 |

For remote connections, the endpoint to connect to (defaults to C<http://localhost:4444>). |
190 |
|
|
|
191 |
|
|
=item proxy => $proxyspec |
192 |
|
|
|
193 |
|
|
The proxy to use (same as the C<proxy> argument used by |
194 |
|
|
L<AnyEvent::HTTP>). The default is C<undef>, which disables proxies. To |
195 |
|
|
use the system-provided proxy (e.g. C<http_proxy> environment variable), |
196 |
root |
1.49 |
specify the string C<default>. |
197 |
root |
1.1 |
|
198 |
|
|
=item autodelete => $boolean |
199 |
|
|
|
200 |
|
|
If true (the default), then automatically execute C<delete_session> when |
201 |
root |
1.43 |
the WebDriver object is destroyed with an active session. If set to a |
202 |
root |
1.1 |
false value, then the session will continue to exist. |
203 |
|
|
|
204 |
root |
1.43 |
Note that due to bugs in perl that are unlikely to get fixed, |
205 |
|
|
C<autodelete> is likely ineffective during global destruction and might |
206 |
|
|
even crash your process, so you should ensure objects go out of scope |
207 |
|
|
before that, or explicitly call C<delete_session>, if you want the session |
208 |
|
|
to be cleaned up. |

|
210 |
root |
1.3 |
=item timeout => $seconds |
211 |
|
|
|
212 |
root |
1.43 |
The HTTP timeout, in (fractional) seconds (default: C<300>). This timeout |
213 |
|
|
is reset on any activity, so it is not an overall request timeout. Also, |
214 |
|
|
individual requests might extend this timeout if they are known to take |
215 |
|
|
longer. |
216 |
root |
1.3 |
|
217 |
root |
1.25 |
=item persistent => C<1> | C<undef> |
218 |
|
|
|
219 |
|
|
If true (the default) then persistent connections will be used for all |
220 |
|
|
requests, which assumes you have a reasonably stable connection (such as |
221 |
|
|
to C<localhost> :) and that the WebDriver has a persistent timeout much |
222 |
|
|
higher than what L<AnyEvent::HTTP> uses. |
223 |
|
|
|
224 |
root |
1.40 |
You can force connections to be closed for non-idempotent requests (the |
225 |
|
|
safe default of L<AnyEvent::HTTP>) by setting this to C<undef>. |

318 |
|
|
|
319 |
|
|
This section documents the simplified API, which is really just a very |
320 |
root |
1.41 |
thin wrapper around the WebDriver protocol commands. They all block the |
321 |
|
|
caller until the result is available (using L<AnyEvent> condvars), so must |
322 |
root |
1.1 |
not be called from an event loop callback - see L<EVENT BASED API> for an |
323 |
|
|
alternative. |
324 |
|
|
|
325 |
root |
1.9 |
The method names are pretty much taken directly from the W3C WebDriver |
326 |
root |
1.1 |
specification, e.g. the request documented in the "Get All Cookies" |
327 |
|
|
section is implemented via the C<get_all_cookies> method. |
328 |
|
|
|
329 |
root |
1.9 |
The order is the same as in the WebDriver draft at the time of this |
330 |
root |
1.1 |
writing, and only minimal massaging is done to request parameters and |
331 |
|
|
results. |

Try to connect to the WebDriver and initialize a new session with a |
342 |
|
|
"new session" command, passing the given key-value pairs as value |
343 |
root |
1.1 |
(e.g. C<capabilities>). |
344 |
|
|
|
345 |
|
|
No session-dependent methods must be called before this function returns |
346 |
root |
1.9 |
successfully, and only one session can be created per WebDriver object. |
347 |
root |
1.1 |
|
348 |
root |
1.7 |
On success, C<< $wd->{sid} >> is set to the session ID, and C<< |
349 |
root |
1.1 |
$wd->{capabilities} >> is set to the returned capabilities. |

=head2 ACTION LISTS |
1155 |
|
|
|
1156 |
|
|
Action lists can be quite complicated. Or at least it took a while for |
1157 |
|
|
me to twist my head around them. Basically, an action list consists of a |
1158 |
|
|
number of sources representing devices (such as a finger, a mouse, a pen |
1159 |
root |
1.51 |
or a keyboard) and a list of actions for each source, in a timeline. |
1160 |
root |
1.12 |
|
1161 |
root |
1.36 |
An action can be a key press, a pointer move or a pause (time delay). |
1162 |
root |
1.12 |
|
1163 |
root |
1.36 |
While you can provide these action lists manually, it is (hopefully) less |
1164 |
root |
1.12 |
cumbersome to use the API described in this section to create them. |
1165 |
|
|
|
1166 |
|
|
The basic process of creating and performing actions is to create a new |
1167 |
|
|
action list, adding action sources, followed by adding actions. Finally |
1168 |
|
|
you would C<perform> those actions on the WebDriver. |
1169 |
|
|
|
1170 |
|
|
Most methods here are designed to chain, i.e. they return the web actions |
1171 |
|
|
object, to simplify multiple calls. |
1172 |
|
|
|
1173 |
root |
1.36 |
Also, while actions from different sources can happen "at the same time" |
1174 |
root |
1.51 |
in the WebDriver protocol, this class by default ensures that actions will |
1175 |
|
|
execute in the order specified. |
1176 |
root |
1.36 |
|
1177 |
root |
1.12 |
For example, to simulate a mouse click to an input element, followed by |
1178 |
|
|
entering some text and pressing enter, you can use this: |
1179 |
|
|
|
1180 |
|
|
$wd->actions |
1181 |
root |
1.36 |
->click (0, 100) |
1182 |
root |
1.12 |
->type ("some text") |
1183 |
root |
1.13 |
->key ("{Enter}") |
1184 |
root |
1.12 |
->perform; |
1185 |
|
|
|
1186 |
root |
1.51 |
By default, C<keyboard> and C<mouse> input sources are provided and |
1187 |
|
|
used. You can create your own sources and use them when adding events. The |
1188 |
|
|
above example could be more verbosely written like this: |
1189 |
root |
1.12 |
|
1190 |
|
|
$wd->actions |
1191 |
root |
1.26 |
->source ("mouse", "pointer", pointerType => "mouse") |
1192 |
|
|
->source ("kbd", "key") |
1193 |
root |
1.36 |
->click (0, 100, "mouse") |
1194 |
root |
1.26 |
->type ("some text", "kbd") |
1195 |
|
|
->key ("{Enter}", "kbd") |
1196 |
root |
1.12 |
->perform; |
1197 |
|
|
|
1198 |
root |
1.21 |
When you specify the event source explicitly it will switch the current |
1199 |
root |
1.12 |
"focus" for this class of device (all keyboards are in one class, all |
1200 |
|
|
pointer-like devices such as mice/fingers/pens are in one class), so you |
1201 |
root |
1.51 |
don't have to specify the source for subsequent actions that are on the |
1202 |
|
|
same class. |
1203 |
root |
1.12 |
|
1204 |
|
|
When you use the sources C<keyboard>, C<mouse>, C<touch1>..C<touch3>, |
1205 |
|
|
C<pen> without defining them, then a suitable default source will be |
1206 |
|
|
created for them. |

Finalises and compiles the list, if not done yet, and returns an actions |
1678 |
|
|
object suitable for calls to C<< $wd->perform_actions >>. When called in |
1679 |
|
|
list context, additionally returns the total duration of the action list. |
1680 |
|
|
|
1681 |
|
|
Since building large action lists can take nontrivial amounts of time, |
1682 |
|
|
it can make sense to build an action list only once and then perform it |
1683 |
|
|
multiple times. |

=head2 EVENT BASED API |
1708 |
|
|
|
1709 |
|
|
This module wouldn't be a good AnyEvent citizen if it didn't have a true |
1710 |
|
|
event-based API. |
1711 |
|
|
|
1712 |
|
|
In fact, the simplified API, as documented above, is emulated via the |
1713 |
|
|
event-based API and an C<AUTOLOAD> function that automatically provides |
1714 |
|
|
blocking wrappers around the callback-based API. |
1715 |
|
|
|
1716 |
|
|
Every method documented in the L<SIMPLIFIED API> section has an equivalent |
1717 |
|
|
event-based method that is formed by appending a underscore (C<_>) to the |
1718 |
|
|
method name, and appending a callback to the argument list (mnemonic: the |
1719 |
|
|
underscore indicates the "the action is not yet finished" after the call |
1720 |
|
|
returns). |
1721 |
|
|
|
1722 |
|
|
For example, instead of a blocking calls to C<new_session>, C<navigate_to> |
1723 |
|
|
and C<back>, you can make a callback-based ones: |
1724 |
|
|
|
1725 |
|
|
my $cv = AE::cv; |
1726 |
|
|
|
1727 |
|
|
$wd->new_session ({}, sub { |
1728 |
|
|
my ($status, $value) = @_, |
1729 |
|
|
|
1730 |
|
|
die "error $value->{error}" if $status ne "200"; |
1731 |
|
|
|
1732 |
|
|
$wd->navigate_to_ ("http://www.nethype.de", sub { |
1733 |
|
|
|
1734 |
|
|
$wd->back_ (sub { |
1735 |
|
|
print "all done\n"; |
1736 |
|
|
$cv->send; |
1737 |
|
|
}); |
1738 |
|
|
|
1739 |
|
|
}); |
1740 |
|
|
}); |
1741 |
|
|
|
1742 |
|
|
$cv->recv; |
1743 |
|
|
|
1744 |
|
|
While the blocking methods C<croak> on errors, the callback-based ones all |
1745 |
|
|
pass two values to the callback, C<$status> and C<$res>, where C<$status> |
1746 |
root |
1.9 |
is the HTTP status code (200 for successful requests, typically 4xx or |
1747 |
root |
1.1 |
5xx for errors), and C<$res> is the value of the C<value> key in the JSON |
1748 |
|
|
response object. |
1749 |
|
|
|
1750 |
|
|
Other than that, the underscore variants and the blocking variants are |
1751 |
|
|
identical. |

|
|
1753 |
|
|
=head2 LOW LEVEL API |
1754 |
|
|
|
1755 |
root |
1.9 |
All the simplified API methods are very thin wrappers around WebDriver |
1756 |
|
|
commands of the same name. They are all implemented in terms of the |
1757 |
root |
1.27 |
low-level methods (C<req>, C<get>, C<post> and C<delete>), which exist |
1758 |
root |
1.1 |
in blocking and callback-based variants (C<req_>, C<get_>, C<post_> and |
1759 |
|
|
C<delete_>). |
1760 |
|
|
|
1761 |
|
|
Examples are after the function descriptions. |

1766 |
|
|
|
1767 |
|
|
=item $value = $wd->req ($method, $uri, $body) |
1768 |
|
|
|
1769 |
|
|
Appends the C<$uri> to the C<endpoint/session/{sessionid}/> URL and makes |
1770 |
|
|
a HTTP C<$method> request (C<GET>, C<POST> etc.). C<POST> requests can |
1771 |
|
|
provide a UTF-8-encoded JSON text as HTTP request body, or the empty |
1772 |
|
|
string to indicate no body is used. |
1773 |
|
|
|
1774 |
|
|
For the callback version, the callback gets passed the HTTP status code |
1775 |
|
|
(200 for every successful request), and the value of the C<value> key in |
1776 |
|
|
the JSON response object as second argument. |
1777 |
|
|
|
1778 |
|

=item $wd->get_ ($uri, $cb->($status, $value)) |

1780 |

1781 |
|
|

|
Simply a call to C<req_> with C<$method> set to C<GET> and an empty body. |

1786 |
|
|
=item $value = $wd->post ($uri, $data) |
1787 |
|
|
|
1788 |
|
|
Simply a call to C<req_> with C<$method> set to C<POST> - if C<$body> is |
1789 |
|
|
C<undef>, then an empty object is send, otherwise, C<$data> must be a |
1790 |
|
|
valid request object, which gets encoded into JSON for you. |
1791 |
|
|
|
1792 |
|
|
=item $wd->delete_ ($uri, $cb->($status, $value)) |
1793 |
|
|
|
1794 |
|
|
=item $value = $wd->delete ($uri) |
1795 |
|
|
|
1796 |
|
|
Simply a call to C<req_> with C<$method> set to C<DELETE> and an empty body. |

This module was unintentionally created (it started inside some quickly |
1820 |
|
|
hacked-together script) simply because I couldn't get the existing |
1821 |
root |
1.41 |
C<Selenium::Remote::Driver> module to work reliably, ever, despite |
1822 |
|
|
multiple attempts over the years and trying to report multiple bugs, which |
1823 |
|
|
have been completely ignored. It's also not event-based, so, yeah... |
