A mailing list improves communication for all the people interested in a 01.org Project: developers, final users and contributors. A more direct channel to solve your questions and help others to get involved.
fMBT generates and executes tests automatically. It very quickly finds and tests paths that would never be tested by human test designers. This increases test coverage and cuts down test maintenance efforts, when compared to traditional test automation.
Aniello Barletta gave a talk on model-based testing in PyCon Italy 2016 on April 15th. His talk included fMBT live demo. Feedback was great. Congratulations, Aniello, and thanks for your contributions to the fMBT project! You can find Aniello's slides here.
