示例1: it
it('should jump scroll position down and slowly scroll back up', async () => {
// The estimate of the total content size is exactly correct, so we wind up scrolled to the
// same place as if we slowly scrolled down.
await browser.executeAsyncScript(scrollViewportTo, viewport, 2000);
const offScreen = element(by.css('.demo-virtual-scroll-uniform-size [data-index="39"]'));
const onScreen = element(by.css('.demo-virtual-scroll-uniform-size [data-index="40"]'));
expect(await isVisibleInViewport(offScreen, viewport)).toBe(false);
expect(await isVisibleInViewport(onScreen, viewport)).toBe(true);
// As we slowly scroll back up we should wind up back at the start of the content.
await browser.executeAsyncScript(smoothScrollViewportTo, viewport, 0);
const first = element(by.css('.demo-virtual-scroll-uniform-size [data-index="0"]'));
expect(await isVisibleInViewport(first, viewport)).toBe(true);
});示例2: it
