title: Junit test case
body: <pre><code>public static String generateSaltString() {
      SecureRandom random = new SecureRandom();
      byte[] salt = random.generateSeed(12);
  
      return byteToBase64(salt);
  }
  </code></pre>
  
  <p>Wondering how to write test case using Junit for this method.
  Any suggestion?</p>
