I wonder if we could stream the gutter results per test? Before we run the test, we add a gray dot, after we run it, we make it red or green?

[Sleepful]

Oh so that way the tests update the indicator as they are ran on the server, super cool!

This is what it looks like :)

@Sleepful awesome! Some tiny comments from me :)

@jonatanklosko code almost done cooking...maybe? 🍳

@Sleepful looks good, final nitpicks. Please run mix format.all to make CI happy :)

[jonatanklosko]

@Sleepful are you running mix format.all (or npm run format in assets)? It seems the formatter doesn't use the right configuration.

[Sleepful]

@jonatanklosko aha yeah. I tried both commands. I am struggling slightly with this prettier thing. It seems this repo does not contain a prettierrc config file, so maybe my system is picking up some custom default configuration that is different from this project. Well, that is my best guess right now.

[Sleepful]

should work now :)
yeah I have a particular .prettierc in my home directory that I use as default config. Since the prettier will travel up directories until it finds a config, it was finding my personal config. So removed my default prettierc and it worked fine

[Sleepful]

Exciting!!! Thanks for the help @jonatanklosko
