SQL Parser Test #

Prepare Data #

Unlike the Integration test, the SQL parse test does not need a specific database environment, just define the sql to parse, and the assert data:

SQL Data #

As mentioned sql-case-id in Integration test，test-case-id could be shared in different module to test, and the file is at shardingsphere-sql-parser/shardingsphere-sql-parser-test/src/main/resources/sql/supported/${SQL-TYPE}/*.xml

Assert Data #

The assert data is at shardingsphere-sql-parser/shardingsphere-sql-parser-test/src/main/resources/case/${SQL-TYPE}/*.xml in that xml file, it could assert against the table name, token or sql condition and so on. For example:

<parser-result-sets>
    <parser-result sql-case-id="insert_with_multiple_values">
        <tables>
            <table name="t_order" />
        </tables>
        <tokens>
            <table-token start-index="12" table-name="t_order" length="7" />
        </tokens>
        <sharding-conditions>
            <and-condition>
                <condition column-name="order_id" table-name="t_order" operator="EQUAL">
                    <value literal="1" type="int" />
                </condition>
                <condition column-name="user_id" table-name="t_order" operator="EQUAL">
                    <value literal="1" type="int" />
                </condition>
            </and-condition>
            <and-condition>
                <condition column-name="order_id" table-name="t_order" operator="EQUAL">
                    <value literal="2" type="int" />
                </condition>
                <condition column-name="user_id" table-name="t_order" operator="EQUAL">
                    <value literal="2" type="int" />
                </condition>
            </and-condition>
        </sharding-conditions>
    </parser-result>
</parser-result-sets>

When these configs are ready, launch the test engine in shardingsphere-sql-parser/shardingsphere-sql-parser-test to test SQL parse.
