### Question:
SuperscriptCodec extends CodecImpl { @NonNull @Override public String decode(@NonNull String text) { StringBuilder result = new StringBuilder(); char letter; for (int i = 0; i < text.length(); i++) { letter = text.charAt(i); int a = SUPPER_SCRIPT.indexOf(letter); if (a != -1) { result.append(NORMAL.charAt(a)); incConfident(); } else { result.append(letter); } } return result.toString(); }  @NonNull @Override String encode(@NonNull String text); @NonNull @Override String decode(@NonNull String text); @NonNull @Override String getName(Context context);  }### Answer:
@Test public void decode() throws Exception { Assert.assertEquals(codec.decode(TO_BE_DECODE), TO_BE_ENCODE); }
