An open library used to connect to the ecFeed service. It can be also used as a standalone testing tool. It is integrated with Junit5 and generates a stream of test cases using a selected algorithm (e.g. Cartesian, N-Wise). There are no limitations associated with the off-line version but the user cannot access the on-line computation servers and the model database.

The newest version!
