nunit refactor to xunit.

[xp44mm]

because xunit is my used lib, maybe some body else need it also.

[xp44mm]

just add file ObservableSpecs.xunit.fs. others no change.

I think you forgot to add the paket.references/paket.dependencies for xUnit?
xUnit is also my preffered testing framework \w FsCheck; but should check with @panesofglass .

Also, if we would move the xUnit; I would make the change complete and also update all the other tests and migrate to xUnit.

[xp44mm]

i compile pass the tests in my separate project. but some functionality i can't make sense. and i can't find them in api doc. that is:
open FSharp.Control.Reactive.Testing.Marbles
Observable.switchMap
Observable.exhaustMap
Observable.catchOption
Observable.catchResult
Observable.consumeMap
Observable.consumeNextOn
Observable.serve
so. i comment them out with whole Fact it belong. let tests pass.

[xp44mm]

i have converted all test files. and run the tests is correctly.

[panesofglass]

I'm fine switching to xUnit. Do we know why the builds are failing?

[panesofglass]

Looks like the builds fail due to incorrect dependency listings: Package FsCheck.Xunit was not found in group Main of the paket.lock file.
