Focus

JOSF is a low-code platform built specifically for low-code environments such as OutSystems, Mendix, and PEGA. Both development and test automation benefit from the power and speed of low-code.

Why JOSF makes the difference

Many organizations are moving toward test automation but struggle with instability or high maintenance costs. JOSF breaks that pattern with a solution that truly works.

Automate your tests

Quickly compose test cases using drag and drop. Build logical structures, organize clear descriptions per step or group, and always keep full visibility. Use JOSF’s debug mode to walk through your tests step by step and make instant adjustments. Add tags and your automated tests appear directly in your test suite, ready for scheduled or regular execution.

Easy to maintain

Keep your tests clear and manageable. Reusable components ensure that commonly used steps are built once and used everywhere. Link test cases to a data-driven sheet to easily add variations without extra work. Work more efficiently, avoid duplicates, and keep your test set easy to maintain and future-proof.

Test in any environment

Run your tests in any environment, development, test, acceptance, or even production, with just one click. Switch environments instantly and execute tests wherever you need. Test across browsers like Chrome, Firefox, and Edge for maximum coverage. Using passwords in your tests? Secure them with JOSF Secrets.

Seamless integration

Collaborate on automated tests with Git integration and run them directly in your CI/CD pipeline using JOSF’s CLI solution. Execute tests automatically after every build or on a fixed schedule. Whether you work with Azure DevOps, GitLab, GitHub, or an on-premise setup, JOSF fits right in, ensuring your automation always runs at the right moment.

JOSF: The platform for your low-code environment

With our Core Layer Testing (CLT) approach, JOSF accelerates the automation of OutSystems applications. CLT tests business logic from the user’s perspective, providing robust and cost-efficient tests that align seamlessly with your low-code development.

Alongside CLT for OutSystems, JOSF also integrates with Mendix. This allows us to understand Mendix applications at their core and rapidly create reusable components for UI testing. The result is faster and more reliable automation that adds value to your low-code development from day one.
