+                  While there is considerable skepticism with regard to
+                  interactive theorem provers in testing communities, we
+                  argue that they are a natural choice for (automated)
+                  symbolic computations underlying systematic tests. This
+                  holds in particular for the development on non-trivial
+                  formal test plans of complex software, where some parts of
+                  the overall activity require inherently guidance by a test
+                  engineer. In this paper, we present the underlying methods
+                  for both black box and white box testing in interactive
+                  unit test scenarios. \testgen can also be understood as
+                  a unifying technical and conceptual framework for
+                  presenting and investigating the variety of unit test
