Toster (The Object-oriented Software Testing EnviRonment) is an open source system for sharing a set of tools that will allow developers to implement methods of object-oriented testing. Any method based on UML diagrams and on the software source code can easily be implemented as a Toster module.
The environment itself makes a number of mechanisms available, such as information transfer from UML diagrams, mapping this information to source code, introducing modifications to the source code, launching the tested application or presenting the results.
The Toster environment makes use of the DFT (design for testability) concept by providing a mechanism for transferring certain method-peculiar information from the CASE model.
