185 C<Test::Harness::Selenium> provides an abstracted way of doing Web app testing
186 using the Selenium framework. It will connect to a running Selenium RC server,
187 or start one using ssh(1) to connect to a machine and then launching the RC
188 server and an xvnc(1) instance in which to run the given browser. After the
189 connection is established, Test::Harness::Selenium will read the specified HTML
190 files from disk and massage them into a format that
191 L<Socialtext::WikiFixture::Selenese> can parse and send to the Selenium RC
192 server. The RC server will then script the browser to do the actions described
193 in the HTML files. These actions return results, which Test::Harness::Selenium
194 then interprets as passing or failing as appropriate.

208 Constructor. Accepts a list of key/value pairs according to the following:
214 Hashref. Accepts the keys host, port, start. host and port describe the server
215 on which to start/find the Selenium RC server and possibly the xvnc server.
216 start is a Boolean indicating whether to start the Selenium RC server and xvnc
221 Scalar. The browser to use for testing the app. Must be in a form that Selenium
222 RC understands (e.g. '*firefox'); see the Selenium docs for more info.
226 Scalar. The URL, relative to the machine running Selenium RC, for the base of
227 the app. All requests made to the app are relative to this URL.
231 Scalar. This command will be run by start_app_server to run the app server to

243 files in the given directory, and then formats massages them into data
244 structures that L<Socialtext::WikiFixture::Selenese> can send to the Selenium RC
245 server. test_directory will then output appropriate TAP according to whether the
246 tests and checks passed or failed, respectively.
