Tests a recurrence rule

param
rrule The rule to expand
param
dtstartStr The dtstart to use
param
limit Maximum number of entries to expand. if there are more, "..." is appended to the result. Note that Android's recurrence expansion doesn't support expanding n results, so this is faked by expanding until the endAt date, and then taking limit results.
param
golden The desired results
param
advanceTo The starting date for expansion. dtstartStr is used if null is passed in.
param
endAt The ending date. DEFAULT_END is used if null is passed in.
param
tz The time zone. UTC is used if null is passed in.
throws
Exception if anything goes wrong.
