elm-test-rs VS test

So I'm super interested in knowing more about your setup that makes it so much faster for elm-test than elm-test-rs. Would you mind open an issue in https://github.com/mpizenberg/elm-test-rs ?

To actually run the tests, however, there are currently two options. The first, as noted above, is node-test-runner, which is available from npm at elm-test. This utility will run the tests as defined in your Elm code, and return the results. There is a second option, elm-test-rs, which is written in Rust instead of Node. It has a handful of features that node-test-runner does not have, as well as some downsides (see the Github README for details), but in general both tools work very well for testing Elm code.

The de-facto standard for testing an Elm application is elm-test. However, as noted in the README:

Once all that handwritten C code was solid, I needed to make sure the C generated from Elm was working properly. I found the source for the core library's unit tests and decided to port them into my project and add some of my own tests. You can run the tests in WebAssembly in your browser too. (Funnily enough, one of the biggest challenges was getting the Elm Test framework itself to run! The framework is more complex than the tests themselves. I still need to come back to the fuzzer tests!)

Lesson Learned: Elm has built in recursion improvements for a variety of positive reasons, and you should think in recursion to solve looping problems. Use property/fuzz tests and bounds checking with early exit to prevent this from locking up your UI (i.e if > 9000, omg abort). If you’re algorithm is reasonable, but the data set is just gigantic, offload to a server instead for more horsepower. Or Workers if you don’t have server chops, can’t upload the large data, or don’t trust your server devs. (“But Doc, I’m the server dev!” Good joke. Ever̸y̴b̸ody laugh. Roll on s̵͓̆nâ̶̱re drum. Curtains.)
