What's the best way to debug a CfD test? For instance, the node I'm looking for isn't getting found, and I want to see what the window would look like at that point in the test so I can figure out where the node is.

It was renamed to

ImageComposeScene

. See examples here

Does passing a

time

to

render

advance the clock for coroutines inside launched effects?

No, it just provides the current time for animations. For driving coroutines, you need to use

UnconfinedTestDispatcher

and pass it as

coroutineContext

Are there any anti patterns there, like rendering at a past time after rendering at a future time, or interactions between driving animations with render, and coroutines with the test dispatcher?

like rendering at a past time after rendering at a future time

The time passed to

render

should be monotonic, i.e. you shouldn't try to pass a lower time after you passed a greater time. Probably we'll add a check for that in the future and describe that in the docs.

I supposed to advance the coroutine clock by one second, and then call render with

1500.milliseconds

?

You should advance the clock by 1500 milliseconds, and pass 1500 to

render

. The time inside a coroutine clock should be same as the time passed to

render

function. There is idea to embed the test dispatcher into

ImageComposeScene

, but that is only an idea for now. That would also fix another issue

Thanks for the info. So in general if I'm dealing with coroutine clocks and

ImageComposeScene

I should always keep them in sync? And hopefully in the future this behavior will be embedded in

ImageComposeScene

?

Yes, that is correct

Could there be any issue with using an

AnimatedVisibility

? It doesn't seem to render those mid transition; only pre or post transition.
