  Automatic assessment of code, in particular to support education, is an
important feature included in several Learning Management Systems (LMS), at
least to some extent. Several kinds of assessments can be designed, such as
exercises asking to "fill the following code", "write a function that", or
"correct the bug in the following program", for example. One difficulty for
instructors is to create such programming exercises, in particular when they
are somewhat complex. Indeed, instructors need to write the statement of the
exercise, think about the solution and provide all the additional information
necessary to the platform to grade the assessment. Another difficulty occurs
when instructors want to use their exercises on another LMS platform. Since
there is no standard way to define and describe a coding exercise yet,
instructors have to re-encode their exercises into the other LMS. This paper
presents a tool that can automatically generate programming exercises, from one
single and unique description, and that can be solved in several programming
languages. The generated exercises can be automatically graded by the same
platform, providing intelligent feedback to its users to support their
learning. This paper focuses on and details unit testing-based exercises and
provides insights into new kinds of exercises that could be generated by the
platform in the future, with some additional developments.
