### Question:
DirectoryV3TotpDeleteRequest { @Override public int hashCode() { return Objects.hash(identifier); } DirectoryV3TotpDeleteRequest(String identifier); String getIdentifier(); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void equalObjectsHaveHashCodeEqual() { assertEquals(new DirectoryV3TotpDeleteRequest("expected identifier").hashCode(), transport.hashCode()); }
@Test public void unequalObjectsHaveHasCodeNotEqual() { assertNotEquals(new DirectoryV3TotpDeleteRequest("unexpected identifier").hashCode(), transport.hashCode()); }
