### Question:
RdbmsConfiguration implements Cloneable { public String getWhereCondition() { return null == whereCondition ? "" : whereCondition; }  @SneakyThrows static RdbmsConfiguration clone(final RdbmsConfiguration origin); String getWhereCondition();  }### Answer:
@Test public void assertGetWhereCondition() { RdbmsConfiguration rdbmsConfiguration = new RdbmsConfiguration(); assertThat(rdbmsConfiguration.getWhereCondition(), is("")); rdbmsConfiguration.setWhereCondition("where 1=1"); assertThat(rdbmsConfiguration.getWhereCondition(), is("where 1=1")); }
