Update the type of items
rather than casting to any
? (here and below)

I was going to, but in some of the other tests I read items.length
, so if I change the type I'm going to have to cast in those places instead (since Observable doesn't have .length
)
.toEqual({start: 0, end: 3}, 'newly emitted items should be rendered'); | ||

Is trackBy value the default?

Yes I think so, due to the way the setter works I can't actually pass undefined though. I should probably just make that work.

LGTM, one nit.
// Should create views for the initial rendered items. | ||

(testComponent.cdkForOfViewContainer.createEmbeddedView as any).calls.reset(); |

Rather than casting it to any
, you can cast it to jasmine.Spy
. Alternatively, when you do the spyOn
above, Jasmine returns a reference to the spy which you can use instead of writing out testComponent.cdkForOfViewContainer.createEmbeddedView
. Same goes for the other tests that follow the same pattern.
