Try the Early Access Program release of 2018.2
Our 2018.2 EAP1 is ready. For this version, we have some new features to improve your experience with migration and generator tests. We’ve implemented migration notifications to improve the communication: now you will receive a notification when the project depends on some languages that could not be loaded for some reason and when the migration is postponed.
In addition to the existing family of node and editor tests, we’ve implemented a facility to express high-level assertions for model-to-model transformations. The aim is to ensure a generator, or set of generators, to do their job. It supports both in-process and out-of-process execution, as well as execution from MPS Ant build scripts.
Have a nice day!
