Method Detail

loadDataSet

public org.dbunit.dataset.IDataSet loadDataSet(Class<?> testClass,
                                               String location)
                                        throws Exception

If no resource can be found then null will be returned.

Specified by:

loadDataSet in interface DataSetLoader

Parameters:

testClass - The class under test

location - The location to load

Returns:

a dataset or null

Throws:

Exception - If the dataset cannot be loaded
