We do this quite often. Just pass a HashMap<String, String> to your fixture
method and
wrap those values in a fake HttpRequest. Works great.

Here's an artificial example:

--------------
!define authInfo {
|username|joe|
|password|abc|
}

|User|
|logs in with|${authInfo}|
|and views greeting|Welcome, Joe!|

--------------

public class User extends DoFixture {
public boolean logsInWith(HashMap<String, String> values) {
...
}
public String andViewsGreeting() {
...
}
}
