+Les tests sont organisés en différentes catégories :
+
+  syntax/bad/    refusés à l'analyse lexicale ou syntaxique
+  typing/bad/    refusés à l'analyse sémantique
+  typing/good/   acceptés à l'analyse sémantique
+  exec-fail/     compilés avec succès mais l'exécution du code MIPS doit échouer
+  exec/          compilés et exécutés avec succès, le résultat attendu étant
+                 conforme au fichier .out
+
+Les tests sont cumulatifs i.e.
+
+- les fichiers de typing/bad/, exec-fail/ et exec/ peuvent être
