### Question:
XmiMapping implements Comparable<XmiMapping> { @Override public String toString() { return String.format("{lhs : %s, rhs : %s, status : %s, comment : %s}", lhs, rhs, status, comment); } XmiMapping(final XmiFeature lhs, final XmiFeature rhs, final XmiMappingStatus status, final String tracking, final String comment); @Override int compareTo(final XmiMapping other); @Override boolean equals(Object o); @Override int hashCode(); XmiFeature getLhsFeature(); XmiFeature getRhsFeature(); XmiMappingStatus getStatus(); String getComment(); String getTracking(); @Override String toString();  }### Answer:
@Test public void testToString() { Assert.assertNotNull(XMI_MAPPING.toString()); }
