Automating Test Oracle Generation in DevOps for Industrial Elevators
Ibabe Arrieta, Aitor; OTAEGI GURRUTXAGA, MAIALEN; Sagardui, Goiuria (IEEE, 2022)Orona is a world-renowned elevators developer. During elevators' lives, their software continues to evolve, e.g., due to hardware obsolescence, requirements changes, vulnerabilities, and bug corrections. Such continuous ... -
Evolutionary generation of metamorphic relations for cyber-physical systems
Ayerdi, Jon; Arrieta, Aitor; Sagardui, Goiuria (ACM, 2022)A problem when testing Cyber-Physical Systems (CPS) is the difficulty of determining whether a particular system output or behaviour is correct or not. Metamorphic testing alleviates such a problem by reasoning on the ... -
Generating metamorphic relations for cyber-physical systems with genetic programming: an industrial case study
Ayerdi, Jon; Arrieta, Aitor; Sagardui, Goiuria (ACM, 2021)One of the major challenges in the verification of complex industrial Cyber-Physical Systems is the difficulty of determining whether a particular system output or behaviour is correct or not, the socalled test oracle ... -
Genetic Algorithm-based Testing of Industrial Elevators under Passenger Uncertainty
Arrieta, Aitor; Sagardui, Goiuria (IEEE, 2021)Elevators, as other cyber-physical systems, need to deal with uncertainty during their operation due to several factors such as passengers and hardware. Such uncertainties could affect the quality of service promised by ... -
Microservices for Continuous Deployment, Monitoring and Validation in Cyber-Physical Systems: an Industrial Case Study for Elevators Systems
Ayerdi, Jon; Arrieta, Aitor; Sagardui, Goiuria (IEEE, 2021)Cyber-Physical Systems (CPSs) are systems that integrate digital cyber computations with physical processes. The software embedded in CPSs has a long life-cycle, requiring constant evolution to support new requirements, ... -
Multi-Objective Metamorphic Test Case Selection: an Industrial Case Study (Practical Experience Report)
Ayerdi, Jon; Arrieta, Aitor (IEEE, 2022)Metamorphic testing is a technique that has shown great potential to alleviate the test oracle problem by exploiting the relations among the inputs and outputs of different executions of a system. However, this approach ... -
Performance-Driven Metamorphic Testing of Cyber-Physical Systems
Ayerdi, Jon; Arrieta, Aitor; Sagardui, Goiuria (IEEE, 2022)Cyber-physical systems (CPSs) are a new generation of systems, which integrate software with physical processes. The increasing complexity of these systems, combined with the uncertainty in their interactions with the ... -
QoS-aware Metamorphic Testing: An Elevation Case Study
Ayerdi, Jon; Arrieta, Aitor; Sagardui, Goiuria (IEEE, 2020)Elevators are among the oldest and most widespread transportation systems, yet their complexity increases rapidly to satisfy customization demands and to meet quality of service requirements. Verification and validation ... -
Towards a Taxonomy for Eliciting Design-Operation Continuum Requirements of Cyber-Physical Systems
Ayerdi, Jon; Arrieta, Aitor; Sagardui, Goiuria (IEEE, 2020)Software systems that are embedded in autonomous Cyber-Physical Systems (CPSs) usually have a large life-cycle, both during its development and in maintenance. This software evolves during its life-cycle in order to ... -
Uncertainty-aware Robustness Assessment of Industrial Elevator Systems
Arrieta, Aitor (ACM, 2022)Industrial elevator systems are commonly used software systems in our daily lives, which operate in uncertain environments such as unpredictable passenger traffic, uncertain passenger attributes and behaviors, and hardware ... -
Using Machine Learning to Build Test Oracles: an Industrial Case Study on Elevators Dispatching Algorithms
Arrieta, Aitor; Ayerdi, Jon; Illarramendi, Miren; Sagardui, Goiuria (IEEE, 2021)The software of elevators requires maintenance over several years to deal with new functionality, correction of bugs or legislation changes. To automatically validate this software, test oracles are necessary. A typical ...
