The testing helper class provided a method named `GetTestDataBasePath` that returned the base path to all the data files stored in the VTK-m repo. This is fine, but it was a little cumbersome to build filenames. To make things easier, there is now a new method named `DataPath` that takes a string of the filename (or, rather, subpath) to the file in that directory and automatically builds the path to it.
