Core Layer Testing for OutSystems
Fast, automated feedback on the core of your OutSystems applications

How Core Layer Testing works
Core Layer Testing focuses on the three essential layers of OutSystems applications: UI, API and data. Instead of testing through the often unstable user interface, we test directly against the stable APIs generated by OutSystems.
We use our JOSF framework, which integrates seamlessly with OutSystems without high licensing costs. At organizations such as a.s.r. and Global Shared Services, Core Layer Testing has become the standard because it delivers fast feedback without the maintenance burden of traditional UI testing.
The method fits effortlessly into CI/CD pipelines and scales with your application. Teams can focus on innovation while core quality remains continuously safeguarded.
What Core Layer Testing delivers
With Core Layer Testing, OutSystems teams gain control over both speed and quality. Less maintenance, shorter test cycles and greater confidence in releases make all the difference.
Faster feedback
Get instant insight into the quality of core functionality after every code change, without waiting for slow UI tests.
Less maintenance
Tests remain stable with interface changes because they focus on underlying logic rather than visual elements.
Seamless CI/CD integration
The framework integrates automatically into your existing development workflow and CI/CD pipeline without complex configuration.
More confidence
Teams and stakeholders gain certainty that every release works as intended, as core functionality is continuously validated.
