Switching from module import to .test.ts causes processTicksAndRejections

I was importing the modules into the test.ts and it was working fine.

I decided to use [test-name].test.ts and I started getting this error:

  Server.setupListenHandle [as _listen2] (node:net:1310:16)
  listenInCluster (node:net:1358:12)
  Server.listen (node:net:1445:7)
  Function.listen (node_modules/express/lib/application.js:618:24)
  index.ts:41:7
  fulfilled (index.ts:5:58)
  processTicksAndRejections (node:internal/process/task_queues:94:5)

I found that the temporary fix was -concurrency 1 but that makes it super slow.

My AVA config is as such

"ava": {
    "babel": false,
    "compileEnhancements": false,
    "extensions": [
      "ts"
    ],
    "require": [
      "ts-node/register"
    ],
    "files": [
      "src/tests/*"
    ]
},

Not sure what the fix is here; to do it 'properly'. I will need to import the tests again.

Something fails, yes, but critically you haven't shared the error message itself. Or code.

Judging from the configuration you're using AVA 2? We can't help you there, AVA 3 is the latest stable version.

@novemberborn the code is 10,000s of line. We updated to 3.15.0 and we were seeing the same issue across our TypeScript projects; testing in JavaScript feels very backwards 😂

Is there any reason why this was moved to discussion and out of the bugs area, since it's a bug and not really a discussion? And it will never get looked at now.

The issue is as explained. Doing tests with [some-file-name].test.ts vs just importing it into the root test causes this error.

But you haven't shared the error, only a stack trace of Node.js internals and something from your web server.

AVA just loads the files, there's nothing special about the filename. You also have ts-node/register involved. Have you had a look recently at our TypeScript recipe? There's a couple options available.

Just because you're encountering an error in your project does not mean there's a bug in AVA. At this stage it's more suitable for a discussion. If there's a bug we can move it back or open a new issue.

And here I am, engaging with you, on a Saturday no less.

@novemberborn that was the only error.

"AVA just loads the files, there's nothing special about the filename. You also have ts-node/register involved. Have you had a look recently at our TypeScript recipe? There's a couple options available."

This is not true. When switching from module import to .test.ts it causes the error. I can see that repeated.

I cba with this. If you don't want to help and just move my projects from the bug list then just delete this issue please.
