177 | # Win32 box) |
178 | my $ths = Test::Harness::Selenium->new( |
179 | selenium_rc=> { |
180 | host => 'designers_machine', |
181 | port => 54321, |
182 | start => 0, # they've already got the RC running |
183 | }, |
184 | browser => '*iexplore', # can't live with it, can't live without it |

190 | |
191 | =head1 DESCRIPTION |
192 | |
193 | C<Test::Harness::Selenium> provides an abstracted way of doing Web app testing |
194 | using the Selenium framework. It will connect to a running Selenium RC server, |
195 | or start one using ssh(1) to connect to a machine and then launching the RC |
196 | server and an xvnc(1) instance in which to run the given browser. After the |
197 | connection is established, Test::Harness::Selenium will read the specified HTML |
198 | files from disk and massage them into a format that |
199 | L<Socialtext::WikiFixture::Selenese> can parse and send to the Selenium RC |
200 | server. The RC server will then script the browser to do the actions described |
201 | in the HTML files. These actions return results, which Test::Harness::Selenium |
202 | then interprets as passing or failing as appropriate. |
203 | |
204 | =head1 METHODS |
205 | |
206 | =head2 new |
207 | |
208 | =over 4 |
209 | |
210 | =item arguments: %attrs |
211 | |
212 | =item Return value: new Test::Harness::Selenium object |
213 | |
214 | =back |
215 | |
216 | Constructor. Accepts a list of key/value pairs according to the following: |
217 | |
218 | =over 4 |
219 | |
220 | =item selenium_rc |
221 | |
222 | Hashref. Accepts the keys host, port, start. host and port describe the server |
223 | on which to start/find the Selenium RC server and possibly the xvnc server. |
224 | start is a Boolean indicating whether to start the Selenium RC server and xvnc |
225 | server. |
226 | |
227 | =item browser |
228 | |
229 | Scalar. The browser to use for testing the app. Must be in a form that Selenium |
230 | RC understands (e.g. '*firefox'); see the Selenium docs for more info. |
231 | |
232 | =item app_base |
233 | |
234 | Scalar. The URL, relative to the machine running Selenium RC, for the base of |
235 | the app. All requests made to the app are relative to this URL. |
236 | |
237 | =item app_start_cmd |
238 | |
239 | Scalar. This command will be run by start_app_server to run the app server to |
240 | test. |
241 | |
242 | =back |
243 | |
244 | =head2 test_directory |
245 | |
246 | =item arguments: $dir |
247 | |
248 | =item Return value: None |
249 | |
250 | Object method. test_directory will use L<File::Find::Rule> to find all C<< .html >> |
251 | files in the given directory, and then formats massages them into data |
252 | structures that L<Socialtext::WikiFixture::Selenese> can send to the Selenium RC |
253 | server. test_directory will then output appropriate TAP according to whether the |
254 | tests and checks passed or failed, respectively. |
255 | |
256 | =head2 run_tests_for |
257 | |
258 | =item arguments: $html_file |
259 | |
260 | =item Return value: None |
261 | |
262 | run_tests_for is called by test_directory for each C<< .html >> file it finds in |
263 | the given directory. |
264 | |
265 | =head2 start_app_server, start_app_server |
266 | |
267 | =item Arguments: None |
268 | |
269 | =item Return value: None |
270 | |
271 | Start and stop the app server using the command given to the constructor. |
272 | |
273 | =head2 start_selenium_server, start_selenium_server |
274 | |
275 | =item Arguments: None |
276 | |
277 | =item Return value: None |
278 | |
279 | Start and stop the selenium / xvnc servers using the params given to the |
280 | constructor. |
281 | |
282 | =head1 ENVIRONMENT |
283 | |
284 | =head2 SELENIUM_RC_HOST, SELENIUM_RC_PORT, SELENIUM_RC_START |
285 | |
286 | These values override the matching values in the selenium_rc hashref passed to |
287 | new. |
