What is the difference between InstaCoverage Core and Pro?

InstaCoverage Core is a free version of InstaCoverage that supports the basic functionalities. InstaCoverage Pro adds features to the core version such as LabVIEW API, RT target support or code coverage measurement. You can check a feature comparison of InstaCoverage Core and Pro here 

What does it mean, that test coverage is not 100%?

It means that there is at least one sub-diagram in the VI under test that is not executed by any test case. Diagram disable structures and conditional disable structures are not included in the measurement. 

Can I run InstaCoverage from LabVIEW code?

Yes, InstaCoverage Pro provides a LabVIEW API to run unit tests from a project or from InstaCoverage configuration files. The InstaCoverage API also helps you to generate (HTML, XML or custom) report files.  

Is there an example InstaCoverage project available online?

Yes. Check the InstaCoverage demo project shipped with the InstaCoverage installation.  

Can I use my license for future InstaCoverage versions?

Yes, the licenses are valid for all future versions of InstaCoverage. 

Why do InstaCoverage need admin rights at the installation?

Admin rights during installation are needed to set up icons for files with .instacov extension which is the custom test configuration file of InstaCoverage. 

I see unexpected behavior I do not understand, is there any help?

You can find an error log in your computer under your users Temp folder. If it is not helpful please contact us via e-mail: 

By default, the Temp folder’s location is <USER>/AppData/Local/Temp. 

Can I use InstaCoverage on Linux-based systems?

InstaCoverage is not tested on Linux. Contact us in case you need InstaCoverage for Linux.
