Since it takes a few minutes for anything you make in JIMS to be picked up by Tyler, consider setting up all of the needed cases and documents in advance, then going to re:Search to do the testing. This will also be easier for the Clerk than finding certain kinds of cases/documents which you perhaps have never even had.
Create a test case of each subtype you are supposed to test
Use the Insert function in JIMS
Use case year 1950
Start at sequence number 10000
Last name = "TEST"
First name- use your county name
Set the Middle initial/name to "SUBTYPEDESCR" for now
Add the bare minimum litigant data, including a close date on the Case Tab which matches the file date
Flesh out one of the litigants
Add one of each kind of document you're supposed to test
Add one of the test attorneys as attorney of record
Copy the fleshed-out litigant to all of the test cases
Use the Copy Litigant Data hub option
Customize each each test case
Set the Middle initial/name to indicate the subtype you're testing (e.g. "Eviction- Foreclosure")
When done testing
Keep the case for future testing, or get rid of it by deleting all the litigants
