The SQLUnit Mock Testing Framework is based on the JDBC mock testing framework provided by the MockRunner Project, and allows a developer to test the SQLUnit code without using a database. Its primary value would be to model databases to which members of the SQLUnit development team do not have access.
Instead of a real database, the testing framework relies on introspecting a class specified in the JDBC URL. This class must implement the IMockDatabase interface and contains one or more methods with the following signature:
public MockResultSet methodName(Integer resultSetId);
The actual implementation of IMockDatabase is specified in the connection parameters in the XML test file. In the example below, the "jdbc:mock" string is used by the DriverManager to select the SQLUnitMockDriver to handle the Connection, and the rest of the URL is used to identify the class name which will be used to supply the MockResultSets needed for the tests.
<connection> <driver>net.sourceforge.sqlunit.test.mock.SQLUnitMockDriver</driver> <url>jdbc:mock:net.sourceforge.sqlunit.test.mock.SQLUnitMockDatabase</url> <user /> <password /> </connection>
The AbstracMockDatabase abstract class provides an introspecting implementation of the IMockDatabase#getResultSet() method. It is an abstract class, so it is expected that someone implementing a Mock Database using this mechanism would extend this class. This is the case with the SQLUnitMockDatabase class, which contains various methods that model mock stored procedure calls.
