Class DbUnitFlatXmlReader

java.lang.Object
com.reallifedeveloper.tools.test.database.dbunit.DbUnitFlatXmlReader
public final class DbUnitFlatXmlReader extends Object
A class to read a DBUnit flat XML dataset file and populate a JpaRepository using the information in the file.

This is useful for testing in-memory repositories using the same test cases as for real repository implementations, and also for populating in-memory repositories for testing services, without having to use a real database.

TODO: The current implementation only has basic support for "to many" associations (there must be a &JoinTable annotation on a field, with &JoinColumn annotations), and for enums (an enum must be stored as a string).
