A Method for Exception Scenarios Generation Using Templates of Exceptions

Scenarios are useful to specify and clarify behaviors of system and its user. However, in a scenario-based software development, a lot of scenarios should be written. This paper proposes a method to generate exception scenarios from a normal scenario written with a scenario language using templates of exceptions. This method includes (1) generation of exception plans and (2) generation of exception scenario by a user's selection of these plans. The proposed method enables users to decrease the omission of the possible exception scenarios in the early stages of development. The method will be illustrated with some examples.
