How to test a function containing "waitfor" function without external user input?

I am testing my GUI functions. I am using Java functions in my test class to trigger mouse clicks. It will trigger a popup dialogue. Here the function pauses at the line of "waitfor". I have to manually click a button to close the dialogue, so the code running can continue. How can I make this process fully automatic?

I think I once saw someone simulate pressing buttons through MATLAB Tester... but I cannot seem to find any way to do that at the moment.

Hi,

Starting from MATLAB R2024b, you can programmatically interact with alert and confirmation dialog boxes using 'chooseDialog' and 'dismissDialog' methods. They work with both modal and non-modal dialogs and can automatically select options or close dialogs without manual intervention.

For more information and examples, refer to the following documentations:

1. dismissDialog - https://mathworks.com/help/matlab/ref/matlab.uitest.testcase.dismissdialog.html
2. chooseDialog - https://mathworks.com/help/matlab/ref/matlab.uitest.testcase.choosedialog.html

Hope this helps!

Unfortunately the user is using R2023b. But perhaps they will be willing to upgrade.

Possible ideas:

1. Create a waitfor function for testing in the current directory before testing to see if it can mask the waitfor of MATLAB.
2. Create an environment or a global variable with a special name (such as YourAppName_Debug) before the test, check whether the environment variable exists in the test objective function, and skip the dialog box if it exists.
3. Add an undocumented optional parameter to the function. This parameter is only offered by the developer in the test environment.
