### Question:
DoubleJWT { public JWTVerifier getAccessVerifier() { return accessVerifier; } DoubleJWT(Algorithm algorithm, long accessExpire, long refreshExpire);  DoubleJWT(String secret, long accessExpire, long refreshExpire); String generateToken(String tokenType, long identity, String scope, long expire); Map<String, Claim> decodeAccessToken(String token); Map<String, Claim> decodeRefreshToken(String token); String generateAccessToken(long identity); String generateRefreshToken(long identity); Tokens generateTokens(long identity); JWTVerifier getAccessVerifier(); JWTVerifier getRefreshVerifier(); JWTCreator.Builder getBuilder(); Algorithm getAlgorithm(); Long getAccessExpire(); Long getRefreshExpire();  }### Answer:
@Test public void getAccessVerifier() { DoubleJWT jwt = new DoubleJWT("secret", 1000, 2000); assertNotNull(jwt.getAccessVerifier()); }
