### Question:
ServiceV3TotpPostRequest { @Override public int hashCode() { return Objects.hash(identifier, otp); } ServiceV3TotpPostRequest(String identifier, String otp); String getIdentifier(); String getOtp(); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void equalObjectAreHashEqual() { assertEquals(transport.hashCode(), new ServiceV3TotpPostRequest("identifier", "otp").hashCode()); }
@Test public void differentIdentifiersAreNotHashEqual() { assertNotEquals(transport.hashCode(), new ServiceV3TotpPostRequest("otheridentifier", "otp").hashCode()); }
@Test public void differentOtpAreNotHashEqual() { assertNotEquals(transport.hashCode(), new ServiceV3TotpPostRequest("identifier", "otherotp").hashCode()); }
