### Question:
Token implements Serializable { public static Token getToken() { Token token = new Token(); byte[] bytes = new byte[SALT_LENGTH]; RANDOM.nextBytes(bytes); token.salt = Base64.encodeToString(bytes, false).trim().replace("+", "F"); token.timestamp = Long.toString(Util.unixtime()); token.buildHash(); return token; } Token(String salt, String timestamp); protected  Token(); static Token getToken(); String getTimestamp(); void setTimestamp(String timestamp); String getSalt(); void setSalt(String salt); String getHash();  }### Answer:
@Test public void testGetToken() { Token token = Token.getToken(); assertNotNull("Returned token was null", token); assertNotNull("Returned token salt was null", token.getSalt()); assertNotNull("Returned token timestamp was null", token.getTimestamp()); assertNotNull("Returned token hash was null", token.getHash()); }
