Bug Report

Current Behavior
I'm not able to mock com.day.cq.wcm.foundation.model.responsivegrid.ResponsiveGrid and other models

Expected behavior/code
A mocked version of the sling model.

Environment

• AEM as a Cloud Service SDK Version 2024.10.18459.20241031T210302Z-241000

Hello everyone,
I'm trying to perform some unit testings but I'm not able to mock some core component classes after update to new version of AEM SDK 2024.10.18459.20241031T210302Z-241000

I am using
@mock
private ResponsiveGrid responsiveGrid;

The error I'm getting is the following
`org.mockito.exceptions.base.MockitoException:

Mockito cannot mock this class: class com.day.cq.wcm.foundation.model.responsivegrid.ResponsiveGrid.

If you're not sure why you're getting this error, please open an issue on GitHub.

You are seeing this disclaimer because Mockito is configured to create inlined mocks.
You can learn about inline mocks and their limitations under item #39 of the Mockito class javadoc.
