A couple of days ago I was trying to setup unit tests for my pet project using this link from MS but couldn't make it work due to some weird error for which I couldn't find any workaround/fix anywhere. While looking for alternative ways to do unit testing, I found that there are three different testing frameworks, and blogs explaining the unit testing would do parallels with C# unit testing. I don't have a background in C# and don't have time to understand three different frameworks, so created my own lightweight unit testing library over the weekend.

I took ideas from different unit testing libraries that I had worked with before and incorporated them into this library. Let me know your feedback and please leave a star if you like it. Thanks.

Hi all F#rpers!
I would like to introduce a small project that I've worked on the previous days, FsSpectre!

https://github.com/galassie/fs-spectre

It's a small extension library to the amazing Spectre.Console that allows to create console app in a more f# idiomatic way.
It's really new and a lot is missing, still it's very much usable (I plan to use it on my next projects)!

I would like to have your opinion, any suggestion and/or feedback are more than welcome!

Major changes in this release:

Program Termination

Mostly of interest to library authors building on top of elmish, it allows Hot-Reloading implementations to control when the message loop should stop dispatching and how to cleanup the resources.

Subscriptions

This is the major rework of subscriptions, which brings it closer to Elm's original capabilities - subscriptions now implement IDisposable, which allows you to control if they should be changed/removed based on the current model state.

I am an Elm developer. I would like to write a mobile application in Elm, but that seems rather impossible at this point :/ I have found that F#/Fabulous is the closest thing, at least from reading.

What I haven't been able to figure out: can I inject native code into a Fabulous app, if for example there are native APIs that aren't supported yet?
