I'm encountering a
TypeError: Cannot read properties of undefined (reading 'activeIndex')
error in my Angular component unit test.The issue arises when trying to access swiper.activeIndex in the component.
I think the problem is that i initialize a variable as a HTMLElement, and then it is not recognized as a swiper container.
Could the solution be to mock up the swiper? If so, how?
