### Question:
RecordStructure implements Described, Named { public int getRootLevelMemberCount() { return members.size(); } RecordStructure(final String name, final List<? extends RecordStructureMember> members);  RecordStructure(final String name, final List<? extends RecordStructureMember> members,
            final String description, final InterfaceStructureType structureType); @Override boolean equals(final Object obj); @Override String getDescription(); @Override String getName(); @SuppressWarnings("unchecked") T getRootLevelMember(final int index); int getRootLevelMemberCount(); InterfaceStructureType getStructureType(); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testGetRootLevelMemberCount() { assertThat(recordStructure.getRootLevelMemberCount()).isEqualTo(members.size()); }
