TestMEReq 2.0 is an automated requirements engineering (RE) assistant tool for efficient capture and validation of quality requirements. This tool is able to automatically generate a combination of abstract test cases and mock-up user interface (UI) prototypes from semi-formalised requirements model: Essential Use Cases (EUCs) and Essential User Interface (EUI). It is also augmented with real time communication and collaboration support to allow multiple stakeholders to collaboratively validate the same set of requirements at the same time with different geographical locations. This feature helps to improve and promote effective communication and collaboration between requirements engineer and client-stakeholders, which leads to fast confirmation and agreements on the requirements. Further, it also provides test-authoring template for novice requirements engineers to easily write quality requirements and test.
