235 t::lib::Selenium - Selenium helper module
239 my $s = t::lib::Selenium->new;
240 my $driver = $s->driver;
241 my $base_url = $s->base_url;
243 $driver->get($s->base_url . 'mainpage.pl');
244 $s->fill_form({ input_id => 'value' });
248 The goal of this module is to group the different actions we need
249 when we use automation test using Selenium
255 my $s = t::lib::Selenium->new;
257 Constructor - Returns the object Selenium
258 You can pass login, password, base_url, selenium_addr, selenium_port
259 If not passed, the environment variables will be used
260 KOHA_USER, KOHA_PASS, KOHA_INTRANET_URL, SELENIUM_ADDR SELENIUM_PORT
261 Or koha, koha, syspref staffClientBaseURL, localhost, 4444
267 Will login into Koha.
274 element_id => 'other_value',
277 Will fill the different elements of a form.
278 The keys must be element ids (input and select are supported so far)
279 The values must a string.
285 It will submit the form using the submit button present in in the fieldset with a clas="action".
286 It should be the default way. If it does not work you should certainly fix the Koha interface.
292 This is a bit dirty for now but will evolve depending on the needs
293 3 parameters possible but only the following 2 forms are used:
294 $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
295 $s->click({ id => 'element_id });
297 =head2 click_when_visible
299 $c->click_when_visible
301 Should always be called to avoid the "An element could not be located on the page" error
306 Capture a screenshot and upload it using the excellent lut.im service provided by framasoft
307 The url of the image will be printed on STDERR (it should be better to return it instead)
309 =head2 add_error_handler
310 $c->add_error_handler
312 Add our specific error handler to the driver.
313 It will displayed a trace as well as capture a screenshot of the current screen.
314 So only case you should need it is after you called remove_error_handler
316 =head2 remove_error_handler
317 $c->remove_error_handler
319 Do *not* call this method if you are not aware of what it will do!
320 It will remove any kinds of error raised by the driver.
321 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.
322 You certainly should call it for only one statement then must call add_error_handler right after.
