LUnit is a LabVIEW Unit Testing Framework built on the xUnit unit testing model and inspired by JKI VI Tester. LUnit helps you test driving your LabVIEW development and provides the following key features.

- Fast test execution
- Clear and informative results view
- Run specific tests quickly from right-click menu
- Test results visible directly in LabVIEW project explorer
- Instant loading of UI
- Parallel test execution managed by framework
- LabVIEW API
- Support for extenssion through add-ons

LUnit is integrated into the LabVIEW development environment and the functionality is accessed through the Tools->LUnit menu. From the menu, you may create a new tests or open the LUnit UI to run tests. Tests may also be executed directly from the project explorer by right-clicking on a Test Case and selecting Run Test Case... from the menu.

Release Notes

1.9.2.2 (Feb 16, 2025)

Important TL;DR:
If you are upgrading: 1.) Test methods must start with the prefix "test" and 2.) If you are using LUnit add-ons, you need to upgrade these also.

This release (v1.9.x) contains the following improvements and new features:
- Change: test methods must start with the prefix "test". This reverts the update in v1.8.x, where this requirement was removed. The reason for this is an improvement which significantly reduces test discovery time.
- Change: Internal Runnable.lvclass interface updated. This may require add-ons using these interfaces to update for compatibility.
- Feature: Introduce diff tool which highlights difference between expected and actual result.
- Improvement: Performance improvements to test discovery, test loading and UI loading
- Improvement: Result comparison message calculated on demand and not during test execution.
- Fix: comparison of equal typedeffed datatypes could in edge cases show as unequal
- Fix: show description when comparing 2D arrays
- Fix: minor typos
