### Question:
MessageCryptoStructureDetector { public static boolean isPartPgpInlineEncrypted(@Nullable Part part) { if (part == null) { return false; } if (!part.isMimeType(TEXT_PLAIN) && !part.isMimeType(APPLICATION_PGP)) { return false; } String text = MessageExtractor.getTextFromPart(part, TEXT_LENGTH_FOR_INLINE_CHECK); if (TextUtils.isEmpty(text)) { return false; } text = text.trim(); return text.startsWith(PGP_INLINE_START_MARKER); }  static Part findPrimaryEncryptedOrSignedPart(Part part, List<Part> outputExtraParts); static List<Part> findMultipartEncryptedParts(Part startPart); static List<Part> findMultipartSignedParts(Part startPart, MessageCryptoAnnotations messageCryptoAnnotations); static List<Part> findPgpInlineParts(Part startPart); static byte[] getSignatureData(Part part); static boolean isPartMultipartEncrypted(Part part); static boolean isMultipartEncryptedOpenPgpProtocol(Part part); static boolean isMultipartSignedOpenPgpProtocol(Part part); static boolean isMultipartEncryptedSMimeProtocol(Part part); static boolean isMultipartSignedSMimeProtocol(Part part); static boolean isPartPgpInlineEncrypted(@Nullable Part part);  }### Answer:
@Test public void isPgpInlineMethods__withPgpInlineData__shouldReturnTrue() throws Exception { String pgpInlineData = "-----BEGIN PGP MESSAGE-----\n" + "Header: Value\n" + "\n" + "base64base64base64base64\n" + "-----END PGP MESSAGE-----\n"; MimeMessage message = new MimeMessage(); message.setBody(new TextBody(pgpInlineData)); assertTrue(MessageCryptoStructureDetector.isPartPgpInlineEncrypted(message)); }
@Test public void isPartPgpInlineEncrypted__withSignedData__shouldReturnFalse() throws Exception { String pgpInlineData = "-----BEGIN PGP SIGNED MESSAGE-----\n" + "Header: Value\n" + "\n" + "-----BEGIN PGP SIGNATURE-----\n" + "Header: Value\n" + "\n" + "base64base64base64base64\n" + "-----END PGP SIGNED MESSAGE-----\n"; MimeMessage message = new MimeMessage(); message.setBody(new TextBody(pgpInlineData)); assertFalse(MessageCryptoStructureDetector.isPartPgpInlineEncrypted(message)); }
