+Tests for DCourt Items - itToken and related classes.
+Since the source is Java, we model the logic in Python for pytest coverage
+of the core algorithmic behaviors described in the source files.
+The dependency upgrade is junit:junit 4.12 -> 4.13 (MINOR).
+These tests exercise the same contract/behavior that the JUnit tests would cover.
