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

255 Hashref. Accepts the keys host, port, start. host and port describe the server
256 on which to start/find the Selenium RC server and possibly the xvnc server.
257 start is a Boolean indicating whether to start the Selenium RC server and xvnc
262 Scalar. The browser to use for testing the app. Must be in a form that Selenium
263 RC understands (e.g. '*firefox'); see the Selenium docs for more info.
267 Scalar. The URL, relative to the machine running Selenium RC, for the base of
268 the app. All requests made to the app are relative to this URL.
