This test method does a write and read back test with all POI filesystems in the "data" directory by performing the following actions for each file:

  • Read its property set streams.

  • Create a new POI filesystem containing the origin file's property set streams.

  • Read the property set streams from the POI filesystem just created.

  • Compare each property set stream with the corresponding one from the origin file and check whether they are equal.
