Spec Explorer [1] is a Model-Based Testing (MBT [2] [3]) tool from Microsoft.It extends the Visual Studio Integrated Development Environment with the ability to define a model describing the expected behavior of a software system.
Model-based testing is an application of model-based design for designing and optionally also executing artifacts to perform software testing or system testing. Models can be used to represent the desired behavior of a system under test (SUT), or to represent testing strategies and a test environment.
Model-based testing moves testing to the left side of the Vs, by testing requirements, architecture, and design models. This shift begins testing almost immediately, instead of waiting a long time (traditional testing), medium time (incremental testing), or short time (Agile/DevOps) for software to become available to the right side of the Vs.
For example, finite-state-machine-based modeling [2] [3] – where a system is modeled as a finite-state machine and a program is used to generate test cases that exercise all states – can work well on a system that has a limited number of states but may become overly complex and unwieldy for a GUI (see also model-based testing).
The objective of ADM is to produce standards for model-based reverse engineering of legacy systems. [4] Knowledge Discovery Metamodel (KDM) is the furthest along of these efforts, and describes information systems in terms of various assets (programs, specifications, data, test files, database schemas, etc.).
The MDE approach is meant to increase productivity by maximizing compatibility between systems (via reuse of standardized models), simplifying the process of design (via models of recurring design patterns in the application domain), and promoting communication between individuals and teams working on the system (via a standardization of the terminology and the best practices used in the ...
Symbolic-execution based analysis and testing, in general, has witnessed a significant level of interest from industry. [citation needed] Perhaps the most famous commercial tool that uses dynamic symbolic execution (aka concolic testing) is the SAGE tool from Microsoft. The KLEE and S2E tools (both of which are open-source tools, and use the ...
Model-based design (MBD) is a mathematical and visual method of addressing problems associated with designing complex control, [1] signal processing [2] and communication systems. It is used in many motion control , industrial equipment, aerospace , and automotive applications.
