### Question:
HttpOathOtpLoginModule implements LoginModule { boolean verify_otp(String userName, String otp) { try { String authString = userName + ":" + otp; String authStringEnc = Base64.encodeBase64URLSafeString(authString.getBytes()); BufferedReader in = attemptAuthentication(authStringEnc); String inputLine; while ((inputLine = in.readLine()) != null) { if (inputLine.contains(expectedOutput)) { return true; } } } catch (Exception ex) { log.error("Failed verifying OATH OTP :", ex); } return false; }  boolean abort(); boolean commit(); void initialize(Subject newSubject, CallbackHandler newCallbackHandler,
			Map<String, ?> sharedState, Map<String, ?> options); boolean login(); boolean logout(); static final String OPTION_HTTPOATHOTP_PROTECTED_URL; static final String OPTION_HTTPOATHOTP_EXPECTED_OUTPUT; static final String OPTION_HTTPOATHOTP_MIN_LENGTH; static final String OPTION_HTTPOATHOTP_MAX_LENGTH; static final String OPTION_HTTPOATHOTP_REQUIRE_ALL_DIGITS; static final String OPTION_HTTPOATHOTP_ID_REALM; public String protectedUrl; public String expectedOutput; public int minLength; public int maxLength; public boolean requireAllDigits; public String idRealm; }### Answer:
@Test public void testVerifyBadOtp() { assertFalse( new LocalOathOtpLoginModule() .verify_otp("????????????", "ccccccgetbkhtdelccclkdtugcljfjbjikbvhlbkhllb") ); }
@Test public void testVerifyGoodOtp() { assertTrue( new LocalOathOtpLoginModule() .verify_otp("????????????", "ccccccgetbkhbkjidfvngrtkkiuevbbglktujdukcnvl") ); }
