198 t::lib::Selenium - Selenium helper module

204 my $base_url = $s->base_url;
206 $driver->get($s->base_url . 'mainpage.pl');
207 $s->fill_form({ input_id => 'value' });
211 The goal of this module is to group the different actions we need
212 when we use automation test using Selenium
218 my $s = t::lib::Selenium->new;
220 Constructor - Returns the object Selenium
221 You can pass login, password, base_url, selenium_addr, selenium_port
222 If not passed, the environment variables will be used
223 KOHA_USER, KOHA_PASS, KOHA_INTRANET_URL, SELENIUM_ADDR SELENIUM_PORT
224 Or koha, koha, syspref staffClientBaseURL, localhost, 4444
230 Will login into Koha.
237 element_id => 'other_value',
240 Will fill the different elements of a form.
241 The keys must be element ids (input and select are supported so far)
242 The values must a string.
248 It will submit the form using the submit button present in in the fieldset with a clas="action".
249 It should be the default way. If it does not work you should certainly fix the Koha interface.
255 This is a bit dirty for now but will evolve depending on the needs
256 3 parameters possible but only the following 2 forms are used:
257 $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
258 $s->click({ id => 'element_id });
260 =head2 click_when_visible
262 $c->click_when_visible
264 Should always be called to avoid the "An element could not be located on the page" error
269 Capture a screenshot and upload it using the excellent lut.im service provided by framasoft
270 The url of the image will be printed on STDERR (it should be better to return it instead)
272 =head2 add_error_handler
273 $c->add_error_handler
275 Add our specific error handler to the driver.
276 It will displayed a trace as well as capture a screenshot of the current screen.
277 So only case you should need it is after you called remove_error_handler
279 =head2 remove_error_handler
280 $c->remove_error_handler
282 Do *not* call this method if you are not aware of what it will do!
283 It will remove any kinds of error raised by the driver.
284 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.
285 You certainly should call it for only one statement then must call add_error_handler right after.
