uitest with questdlg - possible?

Hi,

I'm trying to implement a uitest for one of my dialogues. Everything worked well, until a pressing of a button, triggered confirmation dialog (questdlg with "yes"/"no" answers).

The test is stopping at this moment and waits for user interraction.

Is there a way to close this dialog with choosing of an answer option as part of uitest?

Out of curiousity I tried to use

tc.dismissAlertDialog(fig);

where fig is my object under test, which expectingly reported

Error using matlab.ui.internal.Driver/dismissAlert
Unable to find any alert dialog boxes in the figure window.

after I had to close this dialog manually.

EDIT: as alternative, is there a way to find in the code, that it runs within a TestCase? I.e. I can incorporate in production code check for test execution and not show the confirmation dialog, but provide answer immediately or read it from somewhere?

Ideally, if I can find which TestCase is executed, and read parameters from the TestCase!

Thank you!

Hi Nick,

I understand that you are facing an issue in closing the dialog box without manual intervention.

To programmatically click a button in a dialog box during a test in MATLAB, you would typically use the “matlab.uitest.TestCase” class to interact with the UI components. However, “uiconfirm” dialog boxes are modal and block the MATLAB command line, preventing further commands from running until a user makes a selection.

Since you cannot directly interact with the “uiconfirm” dialog in an automated way using “matlab.uitest.TestCase”, you would need to create a custom dialog using “uifigure” and UI components (like “uibutton”) if you want to automate interaction with a dialog box. Once you have a custom dialog with buttons, you can use the press method of the “matlab.uitest.TestCase” object to simulate a button click.

Here's an example of how you might create a custom dialog and then simulate a button click:

function tester(data) 
    % Create a TestCase object for UI testing 
    testCase = matlab.uitest.TestCase.forInteractiveUse; 
    
    app = YourAppName; 
    pause(2);
    
    % Create a custom dialog with buttons 
    dlg = uifigure('Name', 'Confirmation', 'Position', [100 100 250 150]); 
    btnYes = uibutton(dlg, 'Text', 'Yes', 'Position', [50 50 70 25]); 
    btnNo = uibutton(dlg, 'Text', 'No', 'Position', [130 50 70 25]); 
    
    % Pause to ensure the dialog is rendered before trying to interact 
    drawnow; 
    pause(0.5); % Pause for half a second 
    
    % Use the TestCase to press the 'Yes' button 
    testCase.press(btnYes); 
    
    pause(0.5); 
    
    % Additional testing code goes here 
    
    % Close the custom dialog and the app when done 
    delete(dlg); 
    delete(app); 
end 

In case, if you wish to pass the data from workspace into the app when testing, you can modify the function syntax as follows.

function tester(data) 
    % Code 
    
    % The data variable is passed as an argument from workspace 
    app.EditField.Value = data; 
    
    % Code 
end 

When calling this testcase from the command window, we need to specify the parameters as well.

tester(data) 

Hope this solution helps.

Thanks,

Ravi
