"SyntaxError: Unexpected token u" when running a file

[MoOx]

Ava 0.9.x (can't use 0.10 atm, see #398 (comment))

I am running ava on a file and am getting probably a weird cache issue. First time is ok, a second time is not (when I run the same file without modified it).

~/Sync/Development/statinamic master*
❯❯ ava src/filename-to-url/__tests__/index.js

  7 passed


~/Sync/Development/statinamic master*
❯ ava src/filename-to-url/__tests__/index.js

SyntaxError: Unexpected token u
    at Object.parse (native)
    at Object.<anonymous> (/Users/MoOx/Sync/Development/statinamic/node_modules/ava/lib/test-worker.js:73:20)

  ✖ src/filename-to-url/__tests__/index.js exited with a non-zero exit code: 1

If I add a new (blank) line in my file, and run again, tests passes. If I run again without modifing it, boom.

Here are is my file

import test from "ava"; import "babel-core/register"

import filenameToUrl from ".."

test(
  "should transform */index.md path to a simple url",
  (t) => t.is(
    filenameToUrl("something/index.md"),
    "something"
  )
)

My test file is longer, but I can reproduce with this simple piece and the following dep that I am testing

import path from "path"

export default function(filename, context) {
  if (context) {
    filename = path.relative(context, filename)
  }

  const url = filename
    // something/index.md => something
    // note this rule work for generated json files too
    .replace(/\bindex\.(md|json)$/, "")
    // something-else.md => something-else
    .replace(/\.md$/, "")
    // replace windows backslash by slash
    .replace(/\\/g, "/")
    // no trailing slash
    .replace(/\/$/, "")
    // no relative url
    .replace(/^\.$/, "")
    .replace(/^\.\//, "")

  return url
}

Can you put this in a repo I can clone and reproduce?

[MoOx]

Sure, done.

$ git clone https://github.com/MoOx/statinamic.git
$ cd statinamic
$ git reset --hard d3b265a87c9f7c484331e30b0d75ee07c66900d1
$ npm install
$ ava --verbose src/filename-to-url/__tests__/index.js
$ ava --verbose src/filename-to-url/__tests__/index.js

To confirm, I am trying this too.

[MoOx]

Well, the demo effect does not seems to work. Closing for now unless I can reproduce.

[MoOx]

Ok I found the issue.
I removed the .cache folder and now I cannot reproduce neither in my previous workspace.

[MoOx]

node_modules/.cache/ava

[MoOx]

Unfortunately, I kept this cache folder to try to reproduce, but it seems I cannot anymore... Sorry :/

@MoOx I've had the same issue just now, turned out I was running the file directly with node (as opposed to with ava cli)

This works:

node ./node_modules/.bin/ava path/to/test.js

This doesnt (regardless of the fact it requires ava in the file):

node path/to/test.js

See the worker, it expects three params.

Running a test file directly via node and omitting ava won't work. We removed this capability looong time ago. AVA's CLI must be used to run the tests.
