For information, some of those tests were already converted in a more
structured format there:

http://www.geoapi.org/geoapi-conformance/apidocs/org/opengis/test/referencing/gigs/doc-files/

The related GeoAPI tests are basically GIGS tests converted to JUnit
statements.

The GIGS test files have some errors, in part due to insufficient number
of digits in some values, in part because of the use of some EPSG codes
that are now deprecated. Some CRS or operations names have also changed
since GIGS has been published. Changes required for getting the test to
pass are documented here:

This is unfinished work we started 6 years ago; we did not had the
resources to continue that work during the last few years.
