A method is provided for creating a behavior pattern of a computer program which comprises at least one source code with a plurality of program operations which are arranged in a logical succession and the source code is provided with annotations. Each annotation is referencing to a respective program operation and the annotations are read out automatically by a modeling tool, which is running on a processing unit and generating the behavior pattern of the computer program by arranging the annotations which have been read out according to the logical succession of the program operations and providing the generated behavior pattern, so that the generated behavior pattern can be represented via a representing unit. Furthermore, an appropriate server and an appropriate network system are provided.
