### Question:
DefaultSAML2Validator implements SAML2Validator { @Override public boolean isDocumentTrusted(Document samlDocument, String issuer) throws KeyStoreException, InvalidAlgorithmParameterException, CertificateException, NoSuchAlgorithmException, MarshalException { return isSignatureTrusted(getSignature(samlDocument), issuer); }  @Override boolean isSignatureTrusted(XMLSignature signature, String issuer); @Override boolean isDocumentTrustedAndValid(Document samlDocument, String issuer); @Override boolean isDocumentTrusted(Document samlDocument, String issuer); @Override boolean isDocumentTrusted(Element element, String issuer); @Override boolean isDocumentValid(Document samlDocument); @Override boolean isSignatureValid(Document samlDocument); @Override Document signDocumentWithSAMLSigner(Document samlDocument, SAML2Signer signer);  }### Answer:
@Test public void testIsUntrustedAssertionTrusted() throws Exception { Document doc = getDocument("adfs-invalid.xml"); Assert.assertTrue(!validator.isDocumentTrusted(doc, "CN=*.slidev.org,OU=Domain Control Validated,O=*.slidev.org")); }
