the class DynamicSqlSourceTest method shouldIterateOnceForEachItemInCollection.

@Test
public void shouldIterateOnceForEachItemInCollection() throws Exception {
    final HashMap<String, String[]> parameterObject = new HashMap<String, String[]>() {

        {
            put("array", new String[] { "one", "two", "three" });
        }
    };
    final String expected = "SELECT * FROM BLOG WHERE ID in (  one = ? AND two = ? AND three = ? )";
    DynamicSqlSource source = createDynamicSqlSource(new TextSqlNode("SELECT * FROM BLOG WHERE ID in"), new ForEachSqlNode(new Configuration(), mixedContents(new TextSqlNode("${item} = #{item}")), "array", "index", "item", "(", ")", "AND"));
    BoundSql boundSql = source.getBoundSql(parameterObject);
    assertEquals(expected, boundSql.getSql());
    assertEquals(3, boundSql.getParameterMappings().size());
    assertEquals("__frch_item_0", boundSql.getParameterMappings().get(0).getProperty());
    assertEquals("__frch_item_1", boundSql.getParameterMappings().get(1).getProperty());
    assertEquals("__frch_item_2", boundSql.getParameterMappings().get(2).getProperty());
}
