_$jscoverage is not defined | blanket 1.2.1 #554

NedalKouissi · 2016-02-05T10:52:14Z

I'm using blanket 1.2.1 with mocha, it gives me this error !
i must downgrade to 1.1.9 to make it work :'(

Snippets from Package.json

"scripts": { "test": "mocha && mocha --require blanket -R html-cov > coverage.html" }, "config": { "blanket": { "pattern": "index.js", "data-cover-never": ["node_modules", "test"] } }

The error

Error: BLANKET-Error parsing instrumented code: ReferenceError: _$jscoverage is not defined at /home/idsfn/Documents/training/mochaGettingStarted/node_modules/blanket/src/index.js:177:37 at Object.__dirname.blanket._blanket.instrument (/home/idsfn/Documents/training/mochaGettingStarted/node_modules/blanket/src/blanket.js:126:17) at Object.require.extensions..js (/home/idsfn/Documents/training/mochaGettingStarted/node_modules/blanket/src/index.js:158:25) at Module.load (module.js:344:32) at Function.Module._load (module.js:301:12) at Module.require (module.js:354:17) at require (internal/module.js:12:17) at Object.<anonymous> (/home/idsfn/Documents/training/mochaGettingStarted/test/index.js:4:12) at Module._compile (module.js:410:26) at Module._extensions..js (module.js:417:10) at Object.require.extensions..js (/home/idsfn/Documents/training/mochaGettingStarted/node_modules/blanket/src/index.js:144:17) at Module.load (module.js:344:32) at Function.Module._load (module.js:301:12) at Module.require (module.js:354:17) at require (internal/module.js:12:17) at /home/idsfn/Documents/training/mochaGettingStarted/node_modules/mocha/lib/mocha.js:219:27 at Array.forEach (native) at Mocha.loadFiles (/home/idsfn/Documents/training/mochaGettingStarted/node_modules/mocha/lib/mocha.js:216:14) at Mocha.run (/home/idsfn/Documents/training/mochaGettingStarted/node_modules/mocha/lib/mocha.js:468:10) at Object.<anonymous> (/home/idsfn/Documents/training/mochaGettingStarted/node_modules/mocha/bin/_mocha:403:18) at Module._compile (module.js:410:26) at Object.Module._extensions..js (module.js:417:10) at Module.load (module.js:344:32) at Function.Module._load (module.js:301:12) at Function.Module.runMain (module.js:442:10) at startup (node.js:136:18) at node.js:966:3

@alex-seville, what up brother !

thom4parisot · 2016-02-11T09:35:47Z

I encountered this issue as well and reverted to 1.1.9 too to make it work.

westy92 · 2016-02-11T22:47:09Z

I just experienced this same error. What are you reverting to version 1.9.1?

NedalKouissi · 2016-02-12T15:44:47Z

@westy92 npm install --save-dev [email protected], you may need sudo :)

westy92 · 2016-02-12T17:13:09Z

If 1.2.1 is the latest version, how can 1.9.1 exist? Something doesn't add up. Do you mean 1.1.9?

NedalKouissi · 2016-02-12T17:51:14Z

@westy92 yes you're right!

alex-seville · 2016-02-18T17:40:35Z

I've published a new version, 1.2.2. Let me know if it changes anything.

thom4parisot · 2016-02-19T11:23:16Z

Hm sadly I still encounter the issue with [email protected]. Here is the trace:

vaunus · 2016-02-26T12:26:53Z

Same issue here when trying to use "use strict"; at the top of some of my project files using blanket 1.2.2.

A very simple example of this:
test.js:

let abc = 123;

Error: BLANKET-Error parsing instrumented code: SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

Fine, so I add use strict:
test.js:

'use strict';
let abc = 123;

And the output:

# mocha --require blanket test.js
/Volumes/workspace/sss/mobile-api/node_modules/blanket/src/index.js:179
                            throw e;
                            ^

Snippet from my package.json:

"blanket": {
  "pattern": "///[\\w-_]+\\.js$/",
    "data-cover-never": [
      "/node_modules/",
      "/test/"
    ],
    "data-cover-ecmaVersion": 6,
    "data-cover-reporter-options": {
      "relativepath": true
    }
}

Tested on various versions of Node 4 and 5.

alex-seville · 2016-02-26T16:38:41Z

Sounds like you're using ES6, you'll need to let Blanket know:
https://github.com/alex-seville/blanket/blob/master/docs/options.md#data-cover-ecmaversion

vaunus · 2016-02-26T17:10:40Z

I have already let Blanket know I'm using ES6. See the snippet from my package.json above which has the "data-cover-ecmaVersion": 6 parameter.

We are using ES6 throughout our codebase but have had to wrap most ES6 files in a function wrapper to get Blanket to work. This doesn't work for top-level files however such as app.js. As soon as I add "use strict"; to this I get this error so we are unable to use ES6 features in these files.

I can reproduce this in a simple example:
test.js:

var abc = 123;

mocha --require blanket test.js 
  0 passing (2ms)

However:
test.js:

'use strict';
var abc = 123;

# mocha --require blanket test.js

This is has been around for a long time, originally report Dec.2013.

I need to run npm install [email protected] to make my tests run.

markvandenbrink · 2016-03-10T22:30:54Z

Same problem here (_$jscoverage is not defined) when using 1.2.1 or 1.2.2. Reverting back to 1.1.9 as workaround.

frankred · 2016-04-21T13:57:44Z

Same with me...

sbefort · 2016-04-24T00:49:41Z

Same with me...

rlk833 · 2016-05-06T18:38:31Z

Same here. Busted. We absolutely need ecmaVersion 6. Tried going to a lower version and other problems occur because of no ecmaVersion 6 support.

kousha-icracked · 2016-05-10T18:10:06Z

I'm having the same problem when using ES6. Running 1.1.9 causes another problem:

Error: BLANKET-Error parsing instrumented code: Error: BLANKET-Error parsing instrumented code: Error: BLANKET-Error parsing instrumented code: Error: Line 17: Unexpected token )

Anyone has a solution?

rbudiharso · 2016-08-12T03:06:28Z

I'm having this problem too with blanket 1.2.3

blanket 1.1.10 and above gives the error "_$jscoverage is not defined" when running the test suite. More details on the error are available at: alex-seville/blanket#554 Use version 1.1.9 which is not affected
