Abstract

Agile software development practices require several stakeholders with different kinds of expertise to collaborate while specifying requirements, designing, and modelling software, and verifying whether developers have implemented requirements correctly. We studied 112 requirements engineering (RE) tools from academia and the features of 13 actively maintained behavior-driven development (BDD) tools, which support various stakeholders in specifying and verifying the application behavior. Overall, we found that there is a growing tool specialization targeted towards a specific type of stakeholders. Particularly with BDD tools, we found no adequate support for non-technical stakeholders-- they are required to use an integrated development environment (IDE)-- which is not adapted to suit their expertise. We argue that employing separate tools for requirements specification, modelling, implementation, and verification is counterproductive for agile development. Such an approach makes it difficult to manage associated artifacts and support rapid implementation and feedback loops. To avoid dispersion of requirements and other software-related artifacts among separate tools, establish traceability between requirements and the application source code, and streamline a collaborative software development workflow, we propose to adapt an IDE as an agile development platform. With our approach, we provide in-IDE graphical interfaces to support non-technical stakeholders in creating and maintaining requirements concurrently with the implementation. With such graphical interfaces, we also guide non-technical stakeholders through the object-oriented design process and support them in verifying the modelled behavior. This approach has two advantages: (i) compared with employing separate tools, creating, and maintaining requirements directly within a development platform eliminates the necessity to recover trace links, and (ii) various natively created artifacts can be composed into stakeholder-specific interactive live in-IDE documentation. These advantages have a direct impact on how various stakeholders collaborate with each other, and allow for rapid feedback, which is much desired in agile practices. We exemplify our approach using the Glamorous Toolkit IDE. Moreover, the discussed building blocks can be implemented in any IDE with a rich-enough graphical engine and reflective capabilities.
