228 t::lib::Selenium - Selenium helper module
232 my $s = t::lib::Selenium->new;
233 my $driver = $s->driver;
234 my $base_url = $s->base_url;
236 $driver->get($s->base_url . 'mainpage.pl');
237 $s->fill_form({ input_id => 'value' });
241 The goal of this module is to group the different actions we need
242 when we use automation test using Selenium
248 my $s = t::lib::Selenium->new;
250 Constructor - Returns the object Selenium
251 You can pass login, password, base_url, selenium_addr, selenium_port
252 If not passed, the environment variables will be used
253 KOHA_USER, KOHA_PASS, KOHA_INTRANET_URL, SELENIUM_ADDR SELENIUM_PORT
254 Or koha, koha, syspref staffClientBaseURL, localhost, 4444
260 Will login into Koha.
267 element_id => 'other_value',
270 Will fill the different elements of a form.
271 The keys must be element ids (input and select are supported so far)
272 The values must a string.
278 It will submit the form using the submit button present in in the fieldset with a clas="action".
279 It should be the default way. If it does not work you should certainly fix the Koha interface.
285 This is a bit dirty for now but will evolve depending on the needs
286 3 parameters possible but only the following 2 forms are used:
287 $s->click({ href => '/module/script.pl?foo=bar', main => 'doc3' }); # Sometimes we have doc or doc3. To make sure we are not going to hit a link in the header
288 $s->click({ id => 'element_id });
290 =head2 click_when_visible
292 $c->click_when_visible
294 Should always be called to avoid the "An element could not be located on the page" error
299 Capture a screenshot and upload it using the excellent lut.im service provided by framasoft
300 The url of the image will be printed on STDERR (it should be better to return it instead)
302 =head2 add_error_handler
303 $c->add_error_handler
305 Add our specific error handler to the driver.
306 It will displayed a trace as well as capture a screenshot of the current screen.
307 So only case you should need it is after you called remove_error_handler
309 =head2 remove_error_handler
310 $c->remove_error_handler
312 Do *not* call this method if you are not aware of what it will do!
313 It will remove any kinds of error raised by the driver.
314 It can be useful in some cases, for instance if you want to make sure something will not happen and that could make the driver exploses otherwise.
315 You certainly should call it for only one statement then must call add_error_handler right after.
