### Question:
StatementExceptions implements JdbiConfig<StatementExceptions> { @SuppressWarnings("PMD.UseStringBufferForStringAppends") protected static String limit(String s, int len) { if (s == null) { return null; } String truncated = s.substring(0, Math.min(len, s.length())); boolean isTruncated = len < s.length(); if (isTruncated) { truncated += "[...]"; } return truncated; } StatementExceptions(); private  StatementExceptions(StatementExceptions other); int getLengthLimit(); StatementExceptions setLengthLimit(int lengthLimit); MessageRendering getMessageRendering(); StatementExceptions setMessageRendering(MessageRendering messageRendering); @Override StatementExceptions createCopy();  }### Answer:
@Test public final void testLimit() { String exception = "This is a very long exception that is used for testing"; assertThat(limit(null, 10)).isEqualTo(null); assertThat(limit(exception, 0)).isEqualTo("[...]"); assertThat(limit(exception, 10)).isEqualTo("This is a [...]"); assertThat(limit(exception, 20)).isEqualTo("This is a very long [...]"); assertThat(limit(exception, 53)).isEqualTo("This is a very long exception that is used for testin[...]"); assertThat(limit(exception, 54)).isEqualTo("This is a very long exception that is used for testing"); assertThat(limit(exception, 99)).isEqualTo("This is a very long exception that is used for testing"); }
