I am quite interested in virtual time. It has applications not only in tests, but in simulation as well. As far as I can understand, you have not reimplemented virtual time, only used the implementation from kotlinx-coroutines. Am I right?

[CLOVIS]

Yes, it's all utility classes to make it more ergonomic, but underneath it's the implementation from kotlinx-coroutines-test.

[altavir]

I see, It would be quite useful to have it as a separate library. I think I've filed this to JB YouTrack.

[CLOVIS]

If you find the link, I'd like to follow it too.

[CLOVIS]

From what I understand though, it's just the Dispatcher that's special, and you could use it without using the rest of the kotlinx-coroutines-test library (you'd still need a dependency on it)

[altavir]

Indeed, but You can't just use it outside of runTest I had to copy the whole construct to my project and change some things tom make it work.

[altavir]

Can't find the issue, maybe I forgot to file it after all...

[altavir]

My own "stolen" implementation is here: https://github.com/SciProgCentre/controls-kt/blob/main/controls-core/src/commonMain/kotlin/space/kscience/controls/time/VirtualTimeDispatcher.kt

[CLOVIS]

It's a shame that it's a copy/paste and not a direct reuse, because then it won't work with Prepared and other similar libraries

[altavir]

Yes, I tried to reuse it, but it is tied to runTest and could not be used outide.

[CLOVIS]

Ah.

[altavir]

So I had to copy and change some internals to make it work with generic coroutines

[CLOVIS]

I wonder if it would be difficult to make it interoperate with Prepared's functions 🤔
