Base class for unit tests of Transform<X>To<Y> Subclasses must call `TransformTestBaseClass.setUp(self)` if they provide their own version. If a package other than afw uses this class then it must override the `getTestDir` method to avoid writing into afw's test directory.

| ) |
Check applyForward and applyInverse for a transform
Parameters
----------
transform : `lsst.afw.geom.Transform`
The transform to check
mapping : `ast.Mapping`
The mapping the transform should use. This mapping
must contain valid forward or inverse transformations,
but they need not match if both present. Hence the
mappings returned by make*PolyMap are acceptable.
