assertEquals(0, model.getRowCount());

model.addSniper(joining);

assertEquals(1, model.getRowCount());

assertRowMatchesSnapshot(0, joining);

}

This is similar to the test for updating the Sniper state that we wrote in “Showing a Bidding Sniper” (page 155), except that we’re calling the new method and matching a different TableModelEvent. We also package up the comparison of the table row values into a helper method assertRowMatchesSnapshot().

We make this test pass by replacing the single SniperSnapshot field with a collection and triggering the extra table event. These changes break the existing Sniper update test, because there’s no longer a default Sniper, so we fix it:

@Test public void

setsSniperValuesInColumns() {

SniperSnapshot joining = SniperSnapshot.joining("item id");

SniperSnapshot bidding = joining.bidding(555, 666);

context.checking(new Expectations() {{

allowing(listener).tableChanged(with(anyInsertionEvent()));
