## IMPORTANT WARNINGS

Directory for ReplaceSchema task

replace-schema-*.sql:
DDL statements for creation of your schema.
You should write your own DDL statements in this file.
(A SQL separator is semicolon ";")

take-finally-*.sql:
SQL statements for check loaded data (or DDL after data loading)
You should write your own SQL statements in this file.
(basically same specifications as replace-schema.sql)

The "data" directory is for data loading like this:

        assertEquals("Page", result[0]);
        assertEquals("Action", result[1]);
        assertEquals("Controller", result[2]);
        assertEquals("ControllerImpl", result[3]);
        assertEquals("Task", result[4]);
        assertEquals("Test", result[5]);
