The LaGriT Test Suite is located on the github repo at LaGriT/test/level01. Each directory contains input files and input.lgi with commands to run.
For each test directory there is a reference directory with expected output. Differences between the “outx3dgen” and “reference/outx3dgen” files will indicate why a test fails. The reference directory also contains all out* mesh files written during the run.
lagrit -out outx3dgen < input.lgi
diff outx3dgen reference/outx3dgen
lagrit < input.lgi
diff lagrit.out reference/outx3dgen
