- Test results visible directly in LabVIEW project explorer
- Instant loading of UI
- Parallel test execution managed by framework
- LabVIEW API

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.
