InSTA 2019

6th International Workshop on Software Test Architecture

conjunction with ICST 2019

6th International Workshop on Software Test Architecture (InSTA) is the 6th series of international workshop on software test architecture. Software test architecture includes analyses of system under test, approaches to design test cases, and notation of software testing. Designing better software test architectures is important for software testing. The software test architecture is a key to the test strategy. In software testing, there are various keywords for test design concepts. However, there are no widely standardized diagrams or notations to communicate the test design concepts, to increase the productivity and reusability of tests by raising their levels of abstraction, to generally grasp the overall perspective of the software for testing it. By focusing on the higher concepts of test architectures, our discussions can raise the quality of the testing.

Test architectures must be approached indirectly as a part of the test strategies. Some organizations are working to establish new ways to design novel test architectures, but there is no unified understanding of the key concepts of test architectures. In InSTA workshop, researchers and practitioners will discuss the research works, industrial experiences and emerging ideas about software test architectures. The topics are concepts of test architectures like as abstraction of test cases, design of test architecture as application or enhancement of existing notation UML and UTP, test requirement analysis like as patterns for test requirement analysis, application of test architecture as quality evaluation of test architecture and other software testing related topics.

- Separation of concerns for test
- Architecture of test suite based on abstract test cases (e.g. design of test levels and test types)
- Types of software test architecture (e.g. architecture of test suite and architecture of test system/environment)
- Similarities, differences and harmonization between test suite architecture and test system architecture
- Similarities and differences among software test architecture, test strategy, test plan and test sub-process in ISO/IEC/IEEE 29119

- Connection of software test architecture design and test case design (e.g. structure of test case based on test architectural components)
- Meta-models or ontology for software test architectures

Test requirement analysis

- Whether software requirement specification is the goal of software test or not?

- Test process improvement based on software test architecture
- Relationships between software architectures and software test architectures
- Typical software test architecture for a domain and/or comparison among domains (e.g. banking, logistics, cloud, automotive, medical, industrial automation and telecommunications)
- Industrial experiments and case studies of software test architectures

Paper Submission

• Research papers (up to 10 pages)
• Industrial experience reports (up to 6 pages)
• Emerging idea proposals (up to 6 pages)
Research papers require both original work and quantitative evaluation. Industrial experience reports require practical insight or actual improvement in industry as well as (quantitative if possible) evaluation. Emerging idea proposals require vision, perspective, concept, new idea, new research theme proposal and cross-technical discussion around test architecture design.

All papers must conform to IEEE's format: http://www.ieee.org/conferences_events/conferences/publishing/templates.html

Workshop papers will be published in the IEEE Digital Library in the form of a post-proceedings.
