Hey Steven
I understand that you want to remove unit tests that are related to project A when you switch from project A to project B.
When you add multiple files, the test tree includes multiple parent nodes, each pointing to a different test file. You can remove a parent node and its children from the test tree by right-clicking the parent node and selecting Remove Test File. To remove all the tests from the test browser, click the three-dot button and select Remove all tests.This way you can remove the unit tests that relate to project A.
Alternatively, Use runtests Function:
If you prefer a programmatic approach, you can use the runtests function in MATLAB to run tests selectively. For example:
cd('path_to_project_B/UnitTest');
result = runtests('*.m');
This script runs all tests in the UnitTest folder for Project B. Adjust the path and file patterns according to your project structure. The goal is to ensure that only the relevant tests for the current project are included and executed.
You can go throught the MathWorks Documentation to have a better understanding of the runtests function
I hope this helps!
