Class AccessibleTrees

java.lang.Object
limn.testing.AccessibleTrees
public final class AccessibleTrees extends Object
Reading a published tree in a test: one node by name, every node in a state, and the whole tree as text for the message of an assertion that failed. The two accessibility test bases each had these three; the tests under them each had a fourth for a node by identifier.
