Add a class you can use to mock hover styles when you run the visual regression test on the component. I'd stick with :hover in you site/app and just use the class for testing this state.

styles.css

.avatar {
  // img styles here
}

.avatar:hover,
.avatar.is-hovered {
  // img hover styles here
}
