Turn off UIFigure visibility during unit test

How can I run unit tests on an app without displaying the UIFigure during the tests? Rendering the graphics makes the tests take 10 times longer.

classdef UI < matlab.apps.AppBase
    ...
end

classdef tUI < matlab.uitest.TestCase
    ...
        % many tests involving UI gestures
    ...
end

Interaction tests using press, drag, etc, require figure visibility to be on in the App Testing Framework.

Make sure you're not unnecessarily creating/destroying the uifigure repeatedly between tests. In most cases, the figure/app only needs to be generated once during TestClassSetup and removed via a teardown. Reducing the figure size may also help with performance.

Hi,

In your code, you can create a function which turn on/off the visibilty of the figures. See the below code for example

function app = TurnOff(fig)
   fig.Visible = 'off';
end

This way, you can show or hide any figure by changing its Visible property.

Hope this helps

I think there is no way to do what I want to do, which is to turn off visibility during unit testing with gestures. If I make the UIFigure invisible as you suggest, I get the following error. It looks like the unit testing gestures require the UIFigure to be visible.
