Core Layer Testing for OutSystems

Fast, automated feedback on the core of your OutSystems applications

Focus on what really matters

When UI tests become slow and hard to maintain

OutSystems speeds up development but also introduces testing challenges. Traditional UI tests are often slow, unstable and maintenance-heavy. With every interface change, tests break, forcing teams to spend more time fixing issues than innovating.

At the same time, rapid releases and reusable components can cause bugs to spread quickly through the application. Teams get stuck between the risk of untested code and the frustration of slow, high-maintenance test suites.

Core Layer Testing solves this by focusing on what truly matters: the core functionality of your OutSystems applications. Instead of endless UI tests, it provides targeted feedback on the layers that make the real difference.

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.
