Call for Papers
Software systems (e.g., smartphone apps, desktop applications, telecommunication infrastructures and enterprise systems, etc.) have strict requirements on software performance. Failing to meet these requirements may cause business losses, customer defection, brand damage, and other serious consequences. In addition to conventional functional testing, the performance of these systems must be verified through load testing or benchmarking to ensure quality service.
Load testing examines the behavior of a system by simulating hundreds or thousands of users performing tasks at the same time. Benchmarking compares the system's performance against other similar systems in the domain. The workshop is not limited by traditional load testing; it is open to any ideas of re-inventing and extending load testing, as well as any other way to ensure systems performance and resilience under load, including any kind of performance testing, resilience / reliability / high availability / stability testing, operational profile testing, stress testing, A/B and canary testing, volume testing, and chaos engineering.
Load testing and benchmarking software systems are difficult tasks that require a deep understanding of the system under test and customer behavior. Practitioners face many challenges such as tooling (choosing and implementing the testing tools), environments (software and hardware setup), and time (limited time to design, test, and analyze). Yet, little research is done in the software engineering domain concerning this topic.
Adjusting load testing to recent industry trends, such as cloud computing, agile / iterative development, continuous integration / delivery, micro-services, serverless computing, AI/ML services, and containers poses major challenges, which are not fully addressed yet.
This one-day workshop brings together software testing and software performance researchers, practitioners, and tool developers to discuss the challenges and opportunities of conducting research on load testing and benchmarking software systems. Our ultimate goal is to grow an active community around this important and practical research topic.
We solicit two tracks of submissions:
- Research or industry papers:
- Short papers (maximum 5 pages)
- Full papers (maximum 8 pages)
- Presentation track for industry or research talks:
- Extended abstract (maximum 700 words)
- Efficient and cost-effective test executions
- Rapid and scalable analysis of the measurement results
- Case studies and experience reports on load testing and benchmarking
- Leveraging cloud computing to conduct large-scale testing
- Load testing and benchmarking on emerging systems (e.g., adaptive/autonomic systems, big data systems, blockchain systems, and cloud services)
- Continuous and Context-driven performance testing
- Load testing and benchmarking in the context of agile software development process
- Using performance models to support load testing and benchmarking
- Building and maintaining load testing and benchmarking as a service
- Efficient test data management for load testing and benchmarking
- Performance / load testing as an integral part of the performance engineering process
- Load testing serverless computing platforms and unique challenges of granular and short-lived containers
- Challenges, methods, and tools associated with load testing complex AI applications, including those that use generative AI and large language models (LLMs)
- Load testing and benchmarking for energy consumption of software systems (embedded and IoT systems, cloud computing, green computing)
- LLM-Driven optimization for load testing
- Performance testing across heterogeneous hardware and deployment tiers (e.g., GPUs, TPUs, and edge devices)
