Abstract State Machine Language (AsmL) is an executable specification language based on the theory of Abstract State Machine (ASM). AsmL is used for system modeling, analysis, simulation and conformance testing.
AsmL is developed by Microsoft's Foundations of Software Engineering (FSE) research team. It integrates fully with the .NET environment and Microsoft's development tools, including Word and Visual Studio .NET.
Unlike a number of programming languages specified for coding and testing, AsmL is geared toward communicating project design. Additionally, AsmL may be used during any stage of development. AsmL specification execution allows for model testing, feature interaction checks, design goal fulfillment or unanticipated event planning.
AsmL is also used to for system specification, which provides users with a system picture based on ASM, a mathematical model of the system‘s evolving runtime state.
AsmL differs from traditional programs in that it provides minimal specifications describing anything related to selected details. AsmL facilitates system state descriptions in terms of variables and operations that make sense to the user.
AsmL is available as a software modeling language in the tool Spec Explorer, which is a Visual Studio 2010 component. An open-source implementation of AsmL is available as Extensible Abstract State Machines (XASM) language.
