fulcro
Hi all, i'm embarking on a full stack fulcro app, starting with react native and expo template. I'm interested in setting up some unit tests to help me get things right. I'm mainly looking for examples of tests, or otherwise small examples that would be useful to get me going (examples of tests or anything relevant). Ideally i would be able to run the same test with just swapping out the root component / Actors to my state machine and have the same tests run. I was hoping to get away without needing to render anything. Tips on where to look / how to proceed would be welcomed.
So, the design of Fulcro is very much intended to have you testing state, NOT UI. Fulcro and all of it’s libraries are CLJC, so if you write everything IN CLJC, you can run a data-centric test suite on ALL of your code. Just make the rendering stuff in #?(:cljs) blocks, and write CLJ-only tests.
You might also look at my work-in-progress on statecharts. I have a new way of composing Fulcro apps I’m experimenting with, which has you write the entire application using statecharts. It’s what I’m going to be using for ALL new apps myself.
Here are two repos related to native, and statecharts (NOTE the statecharts work isn’t released, but it is on github)
Here is a git repo of a young woman I’m helping learn Fulcro/Clojure where we set up a native app…the latest expo is kind of hard, so I’d recommend looking over how we set the “Root” “app” and client up, and use that version of expo if you can. The template is out of date. If you want to send a PR to update the template I would appreciate it. https://gitlab.com/shakira1974949/fulcro-native-app
This is the repo of my experimental work on statecharts. https://github.com/fulcrologic/fulcro-with-statecharts
And of course if you read the statecharts docs https://fulcrologic.github.io/statecharts/ there is a section on testing those as pure data/code: https://fulcrologic.github.io/statecharts/#_testing
I highly recommend statecharts over the legacy UI State Machines.
@tony.kay so what are planning to do with RAD and statecharts? will defstatemachine stay in RAD or will be replaced by statecharts in new major version?
I try very hard to never remove things. That is an incompatible change. Statecharts (the library) will be gaining better integration features.
so you can start to adopt those things as needed
great i'll take a look. So the RAD will be made legacy as well? I had to make a few changes to the template which i will make a pr for. I suppose things will still change alot on that front of statecharts is the way forward.
no RAD isn’t going anywhere
My plan is to make a 100% feature-compatible statechart that will run forms/reports, which you can put on a form or report instead of UISM
so, literally just add a so/statechart foo option to a RAD component, and use the statecharts routing abstraction
