### Question:
Credential implements Comparable<Credential> { public void setIsActiveDirectory(Boolean activeDirectory) { isActiveDirectory = activeDirectory; } Credential();  Credential(String shortKey, String longKey, String account, String region, String application, String environment,
                      String component, String lastUpdatedBy, String lastUpdatedDate);  Credential(String shortKey, String longKey, String account, String region, String application, String environment,
                      String component, String lastUpdatedBy, String lastUpdatedDate, String secret); String getShortKey(); void setShortKey(String shortKey); String getLongKey(); void setLongKey(String longKey); String getAccount(); void setAccount(String account); String getEnvironment(); void setEnvironment(String environment); String getComponent(); void setComponent(String component); String getLastUpdatedBy(); void setLastUpdatedBy(String lastUpdatedBy); ZonedDateTime getLastUpdatedDate(); void setLastUpdatedDate(String lastUpdatedDate); String getApplication(); void setApplication(String application); String getSecret(); void setSecret(String secret); String getRegion(); void setRegion(String region); Boolean getIsActiveDirectory(); void setIsActiveDirectory(Boolean activeDirectory); @Override int compareTo(Credential o); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void Test6RequiredFields() { credential = new Credential(); credential.setIsActiveDirectory(false); Set<ConstraintViolation<Credential>> constraintViolations = localValidatorFactory.validate(credential); assertEquals( 12, constraintViolations.size() ); }
