This contribution focuses on testing behavioral aspects of UML and OCL models. In our approach, a so-called model validator can automatically generate test cases (object models) by using manually written configurations for object models and additional OCL invariants. However, describing configurations can be a challenging task, especially for novel or part-time modelers. This paper presents an extension of the tool USE (UML-based Specification Environment) with valuable options for (a)~filmstrip model configuration and (b)~filmstrip templates in the model validation process. Developers specify the configuration for (application) model elements and accordingly, a filmstrip model configuration and a filmstrip template are automatically generated. A filmstrip template identifies recurring model parts which can reduce model validation time. The newly added functionalities strengthen the underlying testing technique by making it more developer-friendly.
