I'm fairly new to Drools, but a fair amount of digging and searching hasn't
brought me closer to an answer on this:
Is there a way for me to determine, at runtime, which rules were fired and
with what inputs?
I am looking to use this my JUnit tests, to make sure that the rules I want
to be fired are firing when I expect them to.

Do you want to do that in the sense of unit testing to make sure you
have defined the rule correctly?
Or, do you want to understand more about the dynamic behavior as your
system executes for profiling? Or learning more about your model?

Though all of those are worthy pursuits, I want to do it in the sense of
unit testing to make sure that I have defined the rule correctly.
Thanks for your rapid response, by the way. I really appreciate it.

You might think differently about unit testing, set up your tests so
you *know* the data is there, and add or retract facts, and verify
their presence as a matter of success of failure.
There are also more advanced approaches that others will surely share soon.

Just to clarify, for anyone else who might offer advice, my original
desire was to have some kind of information about what rule fired, and
what object it fired for.

Here you go:

Oh and there's this in that project which is a JUnit test for the working memory event
listener. Shows how it can be used.

Ciao, as you mentioned in your original post you're starting with Drools, I
want to share with you I find particularly useful to have a
KnowledgeRuntimeLogger [1] during my JUnit tests.
It basically produce an audit xml file which you can later open with the
Drools tools in the Eclipse IDE with the Drools Audit view [2] and very
precious when I'm starting to write new project and its first tests.
While I'm here I want to mention at the same time, in the early JUnit test I
write, I do normally get a great help by the JUnit test tag timeout element
[3]. It helps me prevent infinite rule firing loop by forcing the test
method termination after a while if not completed; normally I'm bad at this
and when I'm starting a brand new project I tend to bump into this kind of
problems.
There are other helpful stuff, but these are the ones I would start from.
Hope this will help you,
Ciao
Matteo

Stephen has pointed you to a WorkingMemoryEventListener, and next to
it there is also a TrackingAgendaEventListener. Callback methods
beforeActivationFired and afterActivationFired bracket the execution
of a rule's consequence, which, in combination with the WM events,
will show you what a rule changes in WM.
As to the facts participating in the firing of a rule: the Activation
object of before/afterActivationFired lets you retrieve these Objects.
(The list of FactHandle's may contain FactHandle objects that do not
necessarily relate to Facts inserted into Working Memory.)
If your Fact objects provide good toString() methods, putting this all
together is a fairly simple task. Make sure to pick up Stephen's ideas
about filtering - this may even be useful for unit testing.

Good point Wolfgang - I linked to the wrong listener for tracking rule activations!
As Wolfgang alludes, I use object filters all the time for unit testing. It lets me create
assertions about the objects that are in working memory. I find it very valuable when my
rules are inserting new facts, rather than just modifying the fact I inserted.
btw - If your toString() method doesn't give you quite enough details about a fact,
then the objectDetails(Object) method in the following will use reflection (via commons
BeanUtils) to iterate through all the properties of an object and build a big string from
them. Which is a good reason to ensure that all your classes have decent toString()
methods.

As to the facts participating in the firing of a rule: the Activation
object of before/afterActivationFired lets you retrieve these Objects.
(The list of FactHandle's may contain FactHandle objects that do not
necessarily relate to Facts inserted into Working Memory.)
If your Fact objects provide good toString() methods, putting this all
together is a fairly simple task. Make sure to pick up Stephen's ideas
about filtering - this may even be useful for unit testing.

Thank you all very much for your advice! I feel I have what I need to move forward.
