How do I control the execution of class-based unit tests using the coder.runTest function?

I am generating C/C++ code from my MATLAB code and I am verifying it using a set of class-based unit tests. Rather than running all of the tests in a given test class file, I would like to control which tests run when I call the coder.runTest function. How can I do that?

There is a way you can do this using the coder.runTest function. See the steps below. This answer uses the same file names used in this example: Unit Test Generated Code with MATLAB Coder

1) Write a MATLAB script called "run_unit_tests.m" that you will use to run your tests

2) Inside "run_unit_tests.m", call the runtests function from the MATLAB Unit-Test Framework and use the "ProcedureName" Name-Value pair to specify which test you want to run. For instance, you could write:

>> runtests('TestAddOne','ProcedureName', 'reallyAddsOne')

See this link for more information on runtests: Run set of tests - MATLAB runtests

3) Now that you have your script setup, you can pass the name of the script to the coder.runTest function:

>> coder.runTest('run_unit_tests', ['addOne_sil.', mexext])

The coder.runTest function will run whatever code you write in "run_unit_tests.m", and so you can control exactly how the tests run.
