Comment (by Roland Haas):

right. TwoPunctures just generates some ID at very low resolution. The Meudon_Bin_Foo thorns do not have tests. FLRWSolver uses a special “no data file needed” setup for its test. CarpetIOHDF5 has some recover tests (and ID reader) in carpet/CarpetIOHDF5/test/input_initial_data.par and some data files for that (15k data). Same with einsteininitialdata/ReadInterpolate/test/synthetic.par (1MB data). 80MB is definitely too large. Ideally the files would <1MB (they don’t need to be physically sane, so very few modes and few should be sufficient).
