So -- like -- where do I put my test files as .ts?

[SephReed]

Ever heard of the drunk test? It's a UX thing where you see if a person can figure it out when drunk: Facebook passes... so does Paypal.

I can't figure out how to make my /__tests/tets.ts file to run with ava. I think maybe I'm supposed to do something extra for ava to work with .ts files... it's been a month or two. This probably should be on the landing page. I don't know many professionals who don't use typescript, to be frank.

Cheers.

Where do the files go and how do they run?

I don't get it. I need to update package.json? If I'm not installing anything, couldn't ava just figure out that the files end in .ts and pretend package.json said some stuff? I like this project. Hope this gets fixed eventually.

What is this:

"rewritePaths": {
				"src/": "build/"
			}

why would I rewrite a path. Everything is where it's supposed to be. I'm not trying to hack something together here. Is this the default?

[SephReed]

I found this code in one of my old projects:

"ava": {
    "compileEnhancements": false,
    "extensions": [
      "ts"
    ],
    "require": [
      "./src/testing/setupBrowser.js",
      "ts-node/register"
    ]
  }

It's totally different than what I'm finding in your docs but at least looks reasonable.

[SephReed]

I tried a bunch more stuff but finally got it. Holy fuck you guys, it's like two lines of instructions:

1. run this npm i ts-node --save-dev

2. add this to your package.json

{
  "ava": {
      "extensions": [
        "ts"
      ],
      "require": [
        "ts-node/register"
      ]
   }
}

I don't know if this is a bug or feature request issue, but could you add these instructions to your docs WAY UP at the top. It's insane how difficult this is for being --- for better or worse -- an industry standard.

Sorry for being impatient.

There's no special place where you need to place your files.

@ava/typescript, at this stage, assumes you compile your codebase first. You then give it a test file in its original location (eg src/test/thing.ts) and it'll load the build output (given the rewrite path, so perhaps build/test/thing.js).

ts-node/register can be quite slow since it might compile all files over and over again for each test file you have, since AVA uses a new worker process for each test file.

Ah, that makes a lot of sense.

I use a typescript bundler, which skips the .js file output stage entirely.

Could you elaborate on that?

[SephReed]

This is the bundler: https://github.com/fuse-box/fuse-box

One can direct it at a root file and it will proceed to compile it and all of its dependencies into a single .js file. It also does fancy stuff like tree shaking unneeded code.

So it does output a .js file, but not the way that tsc would. I don't have a /dist folder with *.js files that map to *.ts files in /src

[novemberborn]

Does your bundle include the tests? Presumably it includes everything else, right? So then in your tests you'd import the bundle?

[SephReed]

My bundle does not include the tests, and I'd never thought of running the tests using the bundle as the source. I prefer to use .ts files for everything I can as they're much more inspectable. It's nice to be able to meta-click and see the source code of any given thing.

When using AVA, I currently just do it the slow way above. It's still plenty fast, so that's good.
