With FitNesse, some initial configuration steps are necessary. Assuming you have a FitNesse wiki-page hierarchy like this:

Put this in your SeleniumTests.SetUp page:

!| import |
| Rsel    |

You also need to define the requisite rubyslim options in the SeleniumTests page content, so they will apply to all sub-wikis:

!define TEST_SYSTEM {slim}
!define TEST_RUNNER {rubyslim}
!define COMMAND_PATTERN {rubyslim}

If you're using Bundler, you may need to use:

!define TEST_SYSTEM {slim}
!define TEST_RUNNER {bundle exec rubyslim}
!define COMMAND_PATTERN {bundle exec rubyslim}

Once you have created your SetUp page, you can create sibling pages with tests in them. For instance, continuing with the example test hierarchy above, your SeleniumTests.LoginTest might look like this:

| script | selenium test | |
| Open browser                                   |
| Fill in       | Username | with | castle       |
| Fill in       | Password | with | beckett      |
| Click button  | Log in                         |
| Page loads in | 5        | seconds or less     |
| See           | Logged in as castle            |
| Close browser                                  |

By default, the server runs on port 4444, and this is the port that Rsel uses unless you tell it otherwise. Rsel also assumes that you're running selenium-server on your localhost (that is, the same host where FitNesse is running); if you need to use a different host or port number, pass those as a hash argument to the first line of the table. For example, if you are running selenium-server on, port 4455, do this:

| script | selenium test | | !{, port:4455} |

Another useful argument to pass in this hash is stop_on_failure, which causes the test to be aborted whenever any failure occurs:

| script | selenium test | | !{stop_on_failure:true} |

By default, when an error occurs, the failing step is simply colored red, and the test continues. With stop_on_failure set, all steps after the failing step will fail automatically without being executed.

The first argument after selenium test is the URL of the site you will be testing. This URL is loaded when you call Open browser, and all steps that follow are assumed to stay within the same domain. You can navigate around the site by clicking links and filling in forms just as a human user would; you can also go directly to a specific path within the domain with the Visit method:

| Visit | /some/path       |
| Visit | /some/other/path |

These paths are evaluated relative to the domain your test is running in. (It's theoretically possible to navigate to a different domain, but the Selenium driver frowns upon it.)

See the SeleniumTest class documentation for a full list of available methods and how to use them.
