=head1 DESCRIPTION |
28 |
|
29 |
WARNING: THE API IS NOT GUARANTEED TO BE STABLE UNTIL VERSION 1.0. |
30 |
|
31 |
This module aims to implement the W3C WebDriver specification which is the |
32 |
standardised equivalent to the Selenium WebDriver API., which in turn aims |
33 |
at remotely controlling web browsers such as Firefox or Chromium. |
34 |
|
35 |
At the time of this writing, it was so brand new that I ciould only get |
36 |
C<geckodriver> (For Firefox) to work, but that is expected to be fioxed |
37 |
very soon indeed. |
38 |
|
39 |
To make most of this module, or, in fact, to make any reasonable use of |
40 |
this module, you would need to refer to the W3C WebDriver recommendation, |
41 |
which can be found L<here|https://www.w3.org/TR/webdriver1/>: |

=item new AnyEvent::WebDriver key => value... |
150 |
|
151 |
Create a new WebDriver object. Example for a remote WebDriver connection |
152 |
(the only type supported at the moment): |
153 |
|
154 |
my $wd = new AnyEvent::WebDriver host => "localhost", port => 4444; |
155 |
|
156 |
Supported keys are: |
157 |
|
158 |
=over |
159 |
|
160 |
=item endpoint => $string |
161 |
|
162 |
For remote connections, the endpoint to connect to (defaults to C<http://localhost:4444>). |
163 |
|
164 |
=item proxy => $proxyspec |
165 |
|
166 |
The proxy to use (same as the C<proxy> argument used by |
167 |
L<AnyEvent::HTTP>). The default is C<undef>, which disables proxies. To |
168 |
use the system-provided proxy (e.g. C<http_proxy> environment variable), |
169 |
specify a value of C<default>. |
170 |
|
171 |
=item autodelete => $boolean |
172 |
|
173 |
If true (the default), then automatically execute C<delete_session> when |
174 |
the WebDriver object is destroyed with an active session. IF set to a |
175 |
false value, then the session will continue to exist. |
176 |
|
177 |
=item timeout => $seconds |
178 |
|
179 |
The HTTP timeout, in (fractional) seconds (default: C<300>, but this will |
180 |
likely drastically reduce). This timeout is reset on any activity, so it |
181 |
is not an overall request timeout. Also, individual requests might extend |
182 |
this timeout if they are known to take longer. |

=item $sessionstring = $wd->save_session |
219 |
|
220 |
Save the current session in a string so it can be restored load with |
221 |
C<load_session>. Note that only the session data itself is stored |
222 |
(currently the session id and capabilities), not the endpoint information |
223 |
itself. |
224 |
|
225 |
The main use of this function is in conjunction with disabled |
226 |
C<autodelete>, to save a session to e.g., and restore it later. It could |
227 |
presumably used for other applications, suhc as using the same sssion from |
228 |
multiple processes and so on. |

Starts using the given session, as identified by |
235 |
C<$sessionid>. C<$capabilities> should be the original session |
236 |
capabilities, although the current version of this module does not make |
237 |
any use of it. |
238 |
|
239 |
The C<$sessionid> is stored in C<< $wd->{sid} >> (and could be fetched |
240 |
form there for later use), while the capabilities are stored in C<< |
241 |
$wd->{capabilities} >>. |

=head2 SIMPLIFIED API |
274 |
|
275 |
This section documents the simplified API, which is really just a very |
276 |
thin wrapper around the WebDriver protocol commands. They all block (using |
277 |
L<AnyEvent> condvars) the caller until the result is available, so must |
278 |
not be called from an event loop callback - see L<EVENT BASED API> for an |
279 |
alternative. |
280 |
|
281 |
The method names are pretty much taken directly from the W3C WebDriver |
282 |
specification, e.g. the request documented in the "Get All Cookies" |
283 |
section is implemented via the C<get_all_cookies> method. |
284 |
|
285 |
The order is the same as in the WebDriver draft at the time of this |
286 |
writing, and only minimal massaging is done to request parameters and |
287 |
results. |
288 |
|
289 |
=head3 SESSIONS |

293 |
=cut |
294 |
|
295 |
=item $wd->new_session ({ key => value... }) |
296 |
|
297 |
Try to connect to the WebDriver and initialize a new session with a |
298 |
"new session" command, passing the given key-value pairs as value |
299 |
(e.g. C<capabilities>). |
300 |
|
301 |
No session-dependent methods must be called before this function returns |
302 |
successfully, and only one session can be created per WebDriver object. |
303 |
|
304 |
On success, C<< $wd->{sid} >> is set to the session ID, and C<< |
305 |
$wd->{capabilities} >> is set to the returned capabilities. |
306 |
|
307 |
Simple example of creatring a WebDriver object and a new session: |
308 |
|
309 |
my $wd = new AnyEvent::Selenium endpoint => "http://localhost:4545"; |
310 |
$wd->new_session ({}); |
311 |
|
312 |
Real-world example with capability negotiation: |
313 |
|
314 |
$wd->new_session ({ |
315 |
capabilities => { |
316 |
alwaysMatch => { |
317 |
pageLoadStrategy => "eager", |
318 |
unhandledPromptBehavior => "dismiss", |
319 |
}, |
320 |
firstMatch => [ |
321 |
{ |
322 |
browserName => "firefox", |
323 |
"moz:firefoxOptions" => { |
324 |
binary => "firefox/firefox", |
325 |
args => ["-devtools"], |
326 |
prefs => { |
327 |
"dom.webnotifications.enabled" => \0, |
328 |
"dom.disable_beforeunload" => \1, |
329 |
"browser.link.open_newwindow" => 3, |
330 |
"browser.link.open_newwindow.restrictions" => 0, |
331 |
"dom.popup_allowed_events" => "", |
332 |
"dom.disable_open_during_load" => \1, |
333 |
}, |
334 |
}, |
335 |
}, |
336 |
{ |
337 |
# generic fallback |
338 |
}, |
339 |
], |
340 |
|
341 |
}, |
342 |
}); |
343 |
|
344 |
Firefox-specific capability documentation can be found L<on |
345 |
MDN|https://developer.mozilla.org/en-US/docs/Web/WebDriver/Capabilities>, |
346 |
Chrome-specific capability documentation might be found |
347 |
L<here|http://chromedriver.chromium.org/capabilities>, but the latest |
348 |
release at the time of this writing has effectively no WebDriver support |
349 |
at all, and canary releases are not freely downloadable. |
350 |

352 |

=head2 ACTION LISTS |
1033 |
|
1034 |
Action lists can be quite complicated. Or at least it took a while for |
1035 |
me to twist my head around them. Basically, an action list consists of a |
1036 |
number of sources representing devices (such as a finger, a mouse, a pen |
1037 |
or a keyboard) and a list of actions for each source. |
1038 |
|
1039 |
An action can be a key press, a pointer move or a pause (time |
1040 |
delay). Actions from different sources can happen "at the same time", |
1041 |
while actions from a single source are executed in order. |
1042 |
|
1043 |
While you can provide an action list manually, it is (hopefully) less |
1044 |
cumbersome to use the API described in this section to create them. |
1045 |
|
1046 |
The basic process of creating and performing actions is to create a new |
1047 |
action list, adding action sources, followed by adding actions. Finally |
1048 |
you would C<perform> those actions on the WebDriver. |
1049 |
|
1050 |
Virtual time progresses as long as you add actions to the same event |
1051 |
source. Adding events to different sources are considered to happen |
1052 |
concurrently. If you want to force time to progress, you can do this using |
1053 |
a call to C<< ->pause (0) >>. |
1054 |
|
1055 |
Most methods here are designed to chain, i.e. they return the web actions |
1056 |
object, to simplify multiple calls. |
1057 |
|
1058 |
For example, to simulate a mouse click to an input element, followed by |
1059 |
entering some text and pressing enter, you can use this: |
1060 |
|
1061 |
$wd->actions |
1062 |
->click (1, 100) |
1063 |
->type ("some text") |
1064 |
->key ("{Enter}") |
1065 |
->perform; |
1066 |
|
1067 |
By default, keyboard and mouse input sources are provided. You can create |
1068 |
your own sources and use them when adding events. The above example could |
1069 |
be more verbosely written like this: |
1070 |
|
1071 |
$wd->actions |
1072 |
->click (1, 100, "mouse") |
1073 |
->type ("some text") |
1074 |
->key ("{Enter}") |
1075 |
->perform; |
1076 |
|
1077 |
When you specify the event source expliticly it will switch the current |
1078 |
"focus" for this class of device (all keyboards are in one class, all |
1079 |
pointer-like devices such as mice/fingers/pens are in one class), so you |
1080 |
don't have to specify the source for subsequent actions. |
1081 |
|
1082 |
When you use the sources C<keyboard>, C<mouse>, C<touch1>..C<touch3>, |
1083 |
C<pen> without defining them, then a suitable default source will be |
1084 |
created for them. |

Create a new empty action list object. More often you would use the C<< |

$wd->action_list >> method to create one that is already associated with |
1096 |
a given web driver. |

The first time you call this with a givne ID, this defines the event |

source using the extra parameters. Subsequent calls merely switch the |
1113 |
current source for its event class. |
1114 |

It's not an error to define built-in sources (such as C<keyboard> or |
1116 |
C<touch1>) differently then the defaults. |

Example: define a new touch device called C<fatfinger>. |

$wd->actions >> method, then perform it against that WebDriver object. |
1450 |
|
1451 |
There is no underscore variant - call the C<perform_actions_> method with |
1452 |
the action object instead. |
1453 |
|
1454 |
=item $al->perform_release ($wd) |
1455 |
|
1456 |
Exactly like C<perform>, but additionally call C<release_actions> |
1457 |
afterwards. |

=item ($actions, $duration) = $al->compile |
1475 |
|
1476 |
Finalises and compiles the list, if not done yet, and returns an actions |
1477 |
object suitable for calls to C<< $wd->perform_actions >>. When called in |
1478 |
list context, additionally returns the total duration of the action list. |
1479 |
|
1480 |
Since building large action lists can take nontrivial amounts of time, |
1481 |
it can make sense to build an action list only once and then perform it |
1482 |
multiple times. |
1483 |
|
1484 |
Actions must not be added after compiling a list. |

=head2 EVENT BASED API |
1507 |
|
1508 |
This module wouldn't be a good AnyEvent citizen if it didn't have a true |
1509 |
event-based API. |
1510 |
|
1511 |
In fact, the simplified API, as documented above, is emulated via the |
1512 |
event-based API and an C<AUTOLOAD> function that automatically provides |
1513 |
blocking wrappers around the callback-based API. |
1514 |
|
1515 |
Every method documented in the L<SIMPLIFIED API> section has an equivalent |
1516 |
event-based method that is formed by appending a underscore (C<_>) to the |
1517 |
method name, and appending a callback to the argument list (mnemonic: the |
1518 |
underscore indicates the "the action is not yet finished" after the call |
1519 |
returns). |
1520 |
|
1521 |
For example, instead of a blocking calls to C<new_session>, C<navigate_to> |
1522 |
and C<back>, you can make a callback-based ones: |
1523 |
|
1524 |
my $cv = AE::cv; |
1525 |
|
1526 |
$wd->new_session ({}, sub { |
1527 |
my ($status, $value) = @_, |
1528 |
|
1529 |
die "error $value->{error}" if $status ne "200"; |
1530 |
|
1531 |
$wd->navigate_to_ ("http://www.nethype.de", sub { |
1532 |
|
1533 |
$wd->back_ (sub { |
1534 |
print "all done\n"; |
1535 |
$cv->send; |
1536 |
}); |
1537 |
|
1538 |
}); |
1539 |
}); |
1540 |
|
1541 |
$cv->recv; |
1542 |
|
1543 |
While the blocking methods C<croak> on errors, the callback-based ones all |
1544 |
pass two values to the callback, C<$status> and C<$res>, where C<$status> |
1545 |
is the HTTP status code (200 for successful requests, typically 4xx or |
1546 |
5xx for errors), and C<$res> is the value of the C<value> key in the JSON |
1547 |
response object. |
1548 |
|
1549 |
Other than that, the underscore variants and the blocking variants are |
1550 |
identical. |
1551 |
|
1552 |
=head2 LOW LEVEL API |
1553 |
|
1554 |
All the simplified API methods are very thin wrappers around WebDriver |
1555 |
commands of the same name. They are all implemented in terms of the |
1556 |
low-level methods (C<req>, C<get>, C<post> and C<delete>), which exists |
1557 |
in blocking and callback-based variants (C<req_>, C<get_>, C<post_> and |
1558 |
C<delete_>). |
1559 |
|
1560 |
Examples are after the function descriptions. |
1561 |
|
1562 |
=over |
1563 |
|
1564 |
=item $wd->req_ ($method, $uri, $body, $cb->($status, $value)) |
1565 |
|
1566 |
=item $value = $wd->req ($method, $uri, $body) |
1567 |
|
1568 |
Appends the C<$uri> to the C<endpoint/session/{sessionid}/> URL and makes |
1569 |
a HTTP C<$method> request (C<GET>, C<POST> etc.). C<POST> requests can |
1570 |
provide a UTF-8-encoded JSON text as HTTP request body, or the empty |
1571 |
string to indicate no body is used. |
1572 |
|
1573 |
For the callback version, the callback gets passed the HTTP status code |
1574 |
(200 for every successful request), and the value of the C<value> key in |
1575 |
the JSON response object as second argument. |
1576 |
|
1577 |
=item $wd->get_ ($uri, $cb->($status, $value)) |
1578 |
|
1579 |
=item $value = $wd->get ($uri) |
1580 |
|
1581 |
Simply a call to C<req_> with C<$method> set to C<GET> and an empty body. |
1582 |
|
1583 |
=item $wd->post_ ($uri, $data, $cb->($status, $value)) |
1584 |
|
1585 |
=item $value = $wd->post ($uri, $data) |
1586 |
|
1587 |
Simply a call to C<req_> with C<$method> set to C<POST> - if C<$body> is |
1588 |
C<undef>, then an empty object is send, otherwise, C<$data> must be a |
1589 |
valid request object, which gets encoded into JSON for you. |
1590 |
|
1591 |
=item $wd->delete_ ($uri, $cb->($status, $value)) |
1592 |
|
1593 |
=item $value = $wd->delete ($uri) |
1594 |
|
1595 |
Simply a call to C<req_> with C<$method> set to C<DELETE> and an empty body. |

Example: implement C<get_all_cookies>, which is a simple C<GET> request |
1602 |
without any parameters: |
1603 |
|
1604 |
$cookies = $wd->get ("cookie"); |
1605 |
|
1606 |
Example: implement C<execute_script>, which needs some parameters: |
1607 |
|
1608 |
$results = $wd->post ("execute/sync" => { script => "$javascript", args => [] }); |
1609 |
|
1610 |
Example: call C<find_elements> to find all C<IMG> elements: |
1611 |
|
1612 |
$elems = $wd->post (elements => { using => "css selector", value => "img" }); |

=head1 HISTORY |
1617 |
|
1618 |
This module was unintentionally created (it started inside some quickly |
1619 |
hacked-together script) simply because I couldn't get the existing |
1620 |
C<Selenium::Remote::Driver> module to work, ever, despite multiple |
1621 |
attempts over the years and trying to report multiple bugs, which have |
1622 |
been completely ignored. It's also not event-based, so, yeah... |
