Snapshot of style rule(s) #117
Description
It would be nice if we could snapshot style rules, instead of explicitly asserting on them in tests.
e.g. instead of:
expect(component).toHaveStyleRule("transition", "height 50ms ease-out, opacity 50ms ease-out 50ms, transform 50ms ease-out 50ms;");we could do something like (API up for discussion):
expect(component.getStyleRule("transition")).toMatchSnapshot();
