### Question:
X509AuthenticatorConfigModel extends AuthenticatorConfigModel { public boolean isCertValidationEnabled() { return Boolean.parseBoolean(getConfig().get(TIMESTAMP_VALIDATION)); } X509AuthenticatorConfigModel(AuthenticatorConfigModel model);  X509AuthenticatorConfigModel(); boolean getCRLEnabled(); X509AuthenticatorConfigModel setCRLEnabled(boolean value); boolean getOCSPEnabled(); X509AuthenticatorConfigModel setOCSPEnabled(boolean value); boolean getCRLDistributionPointEnabled(); X509AuthenticatorConfigModel setCRLDistributionPointEnabled(boolean value); String getCRLRelativePath(); X509AuthenticatorConfigModel setCRLRelativePath(String path); String getOCSPResponder(); X509AuthenticatorConfigModel setOCSPResponder(String responderUri); String getOCSPResponderCertificate(); X509AuthenticatorConfigModel setOCSPResponderCertificate(String responderCert); MappingSourceType getMappingSourceType(); X509AuthenticatorConfigModel setMappingSourceType(MappingSourceType value); IdentityMapperType getUserIdentityMapperType(); X509AuthenticatorConfigModel setUserIdentityMapperType(IdentityMapperType value); String getRegularExpression(); X509AuthenticatorConfigModel setRegularExpression(String value); String getCustomAttributeName(); X509AuthenticatorConfigModel setCustomAttributeName(String value); String getKeyUsage(); X509AuthenticatorConfigModel setKeyUsage(String value); String getExtendedKeyUsage(); X509AuthenticatorConfigModel setExtendedKeyUsage(String value); boolean getConfirmationPageDisallowed(); boolean getConfirmationPageAllowed(); X509AuthenticatorConfigModel setConfirmationPageDisallowed(boolean value); X509AuthenticatorConfigModel setConfirmationPageAllowed(boolean value); boolean isCanonicalDnEnabled(); X509AuthenticatorConfigModel setCanonicalDnEnabled(boolean value); boolean isCertValidationEnabled(); X509AuthenticatorConfigModel setCertValidationEnabled(boolean value); boolean isSerialnumberHex(); X509AuthenticatorConfigModel setSerialnumberHex(boolean value);  }### Answer:
@Test public void testTimestampValidationAttributeReturnsNull() { X509AuthenticatorConfigModel configModel = new X509AuthenticatorConfigModel(); Assert.assertNull(configModel.getConfig().get(AbstractX509ClientCertificateAuthenticator.TIMESTAMP_VALIDATION)); Assert.assertFalse(configModel.isCertValidationEnabled()); }
