I have a question regarding testing the correct result of a textgen process. I wanna add a root from my language with all the editor features I have defined and then trigger the generation of this model from my unit test. Furthermore I want to check the resulting .txt file against a gold reference, which includes the expected result of the generation. So far I haven't found a way to trigger the textgen process and check the result against the expected result, even though I read the following guide: https://confluence.jetbrains.com/display/MPSD33/Testing+languages
Thanks in advance!
