paradigm that uses models as main assets in all development
phases. While many languages for model manipulation exist
(e.g., for model transformation or code generation), there is
a lack of frameworks to de ne and apply model mutations.
A model mutant is a variation of an original model, created
by speci c model mutation operations. Model mutation has
many applications, for instance, in the areas of model trans-
formation testing, model-based testing or education.
In this paper, we present a domain-speci c language, called
Wodel, for the speci cation and generation of model mu-
tants. Wodel is domain-independent, as it can be used to
generate mutants of models conforming to arbitrary meta-
models. Its development environment is extensible, permit-
ting the incorporation of post-processors for di erent appli-
cations. As an example, we show an application consisting
on the automated generation of exercises for particular do-
mains (automata, class diagrams, electronic circuits, etc.).Thanks to Víctor López Rivero for the initial implementation of the Wodel IDE.
