SyntaxError: Unexpected reserved word with import

[nicolas-zozol]

It looks like babel-istanbul doesn't want to babelize my code.

My code start in src/test/index.js with

import optionTest from './data/option_test';
import tryTest from './data/try_test';

export {
    optionTest, tryTest
}

I launch with :

"scripts": {
    "compile": "babel src --out-dir dist  --source-maps",
    "test": "npm run compile && nodeunit dist/test/index.js",

    "cover": "rm -rf ./coverage && babel-node  ./node_modules/.bin/babel-istanbul cover --dir coverage/istanbul src/test/index.js"
  },
  "devDependencies": {
    "babel-cli": "^6.10.1",
    "babel-core": "^6.10.4",
    "babel-istanbul": "^0.8.0",
    "nodeunit": "~0.9.0",
    ....
  },

And I have

import optionTest from './data/option_test'; ^^^^^^

SyntaxError: Unexpected reserved word

It does the same launching directly >.\node_modules\.bin\babel-istanbul cover --dir coverage\istanbul src\test\index.js

I have ssen that a fellow lauched >.\node_modules\.bin\babel-babel-node .\node_modules\.bin\babel-istanbul cover --dir coverage\istanbul src\test\index.js ; It fails quckly, and I don't feel your lib is written to be launched with babel-node, but it launches it directly. Is it ?

You'll need you run your tests with babel-node. The babel-instabul package is only compiling during the instrumentation of your code. When it is actually running, it also needs to be compiled. Your test command should look something like this:

babel-node node_modules/.bin/babel-istanbul cover nodeunit -- dist/test/index.js

Then I guess it doesn't work on windows :) I have an unexpected token found in the babel-istanbul.cmd file. I will check tomorrow on linux and see.

Your unexpected token error is likely just being thrown from the babel-istanbul cli. The library itself is written in es5, so it should work if you run your test code with babel-node.
