Hello.
In my understanding, there are no official test framework for TouchGFX. It may be helpful what written in the following thread.
https://community.st.com/s/question/0D50X0000BQOcbw/is-there-unit-test-support-in-touchgfx
In my case, I'm using Google Test or CppUnit. In this case, I create my own test project. It may not be difficult.
If there is a TouchGFX unit test update, I would love to know that too!
