can enforce that an invocation only happens when object is (or is not) in a particular state with a when() clause We rewrite our test:

@Test public void announcesMatchForTwoAuctions() { final AuctionSearcher auctionSearch = new AuctionSearcher(searchListener, new AuctionSearcher(searchListener, asList(STUB_AUCTION1, STUB_AUCTION2)); contextchecking(new Expectations() {{ States searching = contextstates("searching"); oneOf(searchListener)searchMatched(STUB_AUCTION1); when(searchingisNot("finished")); oneOf(searchListener)searchMatched(STUB_AUCTION2); when(searchingisNot("finished")); oneOf(searchListener)searchFinished(); then(searchingis("finished")); }}); auctionSearchsearchFor(KEYWORDS); }

When the test opens, searching is in an unde ned (default) state The searcher can report matches as long as searching is not nished When the searcher reports that it has nished, the then() clause switches searching to finished, which blocks any further matches States and sequences can be used in combination For example, if our requirements change so that auctions have to be matched in order, we can add a sequence for just the matches, in addition to the existing searching states The new sequence would con rm the order of search results and the existing states would con rm that the results arrived before the search is nished An expectation can belong to multiple states and sequences, if that s what the protocol requires We rarely need such complexity it s most common when responding to external feeds of events where we don t own the protocol and we always take it as a hint that something should be broken up into smaller, simpler pieces

When Expectation Order Matters

Actually, the order in which jMock expectations are declared is sometimes signi cant, but not because they have to shadow the order of invocation Expectations are appended to a list, and invocations are matched by searching this list in order If there are two expectations that can match an invocation, the one declared rst will win If that rst expectation is actually an allowance, the second expectation will never see a match and the test will fail

The Power of jMock States

jMock States has turned out to be a useful construct We can use it to model each of the three types of participants in a test: the object being tested, its peers, and the test itself We can represent our understanding of the state of the object being tested, as in the example above The test listens for the events the object sends out to its peers and uses them to trigger state transitions and to reject events that would break the object s protocol As we wrote in Representing Object State (page 146), this is a logical representation of the state of the tested object A States describes what the test nds relevant about the object, not its internal structure We don t want to constrain the object s implementation We can represent how a peer changes state as it s called by the tested object For instance, in the example above, we might want to insist that the listener must be ready before it can receive any results, so the searcher must query its state We could add a new States, listenerState:

allowing(searchListener)isReady(); will(returnValue(true)); then(listenerStateis("ready")); oneOf(searchListener)searchMatched(STUB_AUCTION1); when(listenerStateis("ready"));

Finally, we can represent the state of the test itself For example, we could enforce that some interactions are ignored while the test is being set up:

ignoring(auction); when(testStateisNot("running")); testStatebecome("running"); oneOf(auction)bidMore(); when(testStateis("running"));

Even More Liberal Expectations

Finally, jMock has plug-in points to support the de nition of arbitrary expectations For example, we could write an expectation to accept any getter method:

allowing(aPeerObject)method(startsWith("get"))withNoArguments();

or to accept a call to one of a set of objects:

Such expectations move us from a statically typed to a dynamically typed world, which brings both power and risk These are our strongest power tool features sometimes just what we need but always to be used with care There s more detail in the jMock documentation
