Yes! Use a sub-class of TestContext which reads a modified version of
FoodMart as it creates its connection.

Use the TestContext.create() and TestContext.createSubstitutingCube()
methods. See SchemaTest for examples.

I've been intending to clean up tests which use createCube and
createDimension - and also to remove mutant definitions in Foodmart.xml,
such as "Sales 2" and "Sales Ragged" - but I never got round to it.
