Quasar Error jest unit test why error when calling q-dialog component?

Question

Unit testing

I'm trying to unit test on the main quasar framework, using a component from the q-dialog library, when I initialize the call of the modal window, the test fails with an error: UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'ios' of undefined
Also a warning falls: [Vue warn]: Unhandled error during execution of watcher callback at
