The problem is that, after LoadAllPackages();, the zero of an algebra is displayed by ViewObj as "0" rather than " of ...", causing diffs in the tests. The proposed fix is to replace ViewObj by PrintObj where necessary. For example, f := AllHomsOfAlgebras(R,A);; now ends ";;" and then mgif is defined as List(g,h->MappingGeneratorsImages(h));; and then mgif is Print-ed.
