Unit test: access code in one project by another project in the same workspace

[GregR]

I want to setup simple unit testing using something like tinytest or minctest running on the target processor. The idea is to have the application project and a test project in the same workspace. The test project will only implement a UART for reporting results and maybe some debug LEDs. It will run the unit test code that exercises functions in the application project. I want this to be as nonintrusive of the application code as possible. I don't want to do things like breakout the code to be tested into some kind of common code section... What is the best approach? I've tried setting up linked folders but I haven't been able to make that work. I don't think it matters but the application is a netxduo project.

You can drag/drop files within the IDE and create symbolic links to the file. If you structure your files correctly, you can use the same code in both applications.

Another approach would be to keep your unit tests inside the app project in a separate folder and use different build configurations control which files that are included / excluded in unit test build vs application build.

So, there should be plenty of flexibility. Let us know if how you progress and which the major pain points are!
