I've tried using the latest version of istanbul but that doesn't help any. Is there any more info I can provode to help troubleshoot this?

[jramoyo]

I'm getting the same error - it's broken starting 0.2.7.

[mtfranchetto]

Same error.

[osdio]

I also meet the same error

[piecyk]

The problem is that browserify transform Istanbul takes care the coverage report... setting karma preprocessors for coverage has no effect on that.

fix: when using browserify dont create source code caching

[maksimr]

Seems problem in this commit.

[jsdevel]

So locking the dependency for karma-coverage to 0.2.6 solved the issue for me after clearing node_modules and npm installing.

[nicdutil]

Same here. Thanks @jsdevel !!! Finally got coverage working with karma and browserify!

I just want to mention that I'm running karma on Linux (Ubuntu 14.04). I'm trying to get all of this to work on windows, but karma-browserify /browserify is giving me errors about finding my modules..

[tramck]

+1 to this issue. @jsdevel 's solution worked for me.

[leonard84]

+1 downgrading to 0.2.6 worked like @jsdevel described

[jenswegar]

+1 for this issue @jsdevel downgrade fix worked for me as well

[neilrees]

+1 downgrading to 0.2.6 also worked here

[peter-mouland]

+1 downgrading

[SomeKittens]

Also ran into this issue. Downgrading worked.

[dsuckau]

For me the same, downgrading to 0.2.6 worked

[jskrzypek]

+1 downgrading to 0.2.6, but any idea of when we will be able to upgrade and still have working coverage with browserify?

[jasonslyvia]

+1, downgrading worked.

[codepunkt]

+1 here, downgraded to 0.2.6.

Please investigate!

@akoval See my issue: https://github.com/karma-runner/karma-coverage/issues/122#issuecomment-110399483

[dignifiedquire]

Should be fixed in 0.4.0

[Tin-Nguyen]

Hi @Dignifiedquire ,

After upgraded the component to 0.4.0, I got the error ERROR [coverage]: [TypeError: Cannot set property 'covered' of undefined]

Tried with 0.3.1, I got the error ERROR [coverage]: [TypeError: Cannot call method 'split' of undefined]

I just got the issue when using the transform babelify for browserify

Is there anyone has resolved the issue yet? :((

[Tin-Nguyen]

I've just checked and realized that the component still be 0.3.1. I still got the error ERROR [coverage]: [TypeError: Cannot set property 'covered' of undefined]

I have also checked the release of the component and cannot find out the version 0.4.0. The latest version now is 0.3.0.

[dignifiedquire]

Are you sure you are running against the official npm registry, I get this:

❯ npm view karma-coverage@latest version
0.4.2

as well as https://www.npmjs.com/package/karma-coverage which shows the latest version being 0.4.2

[Tin-Nguyen]

Yes, sorry for my mistake. I did it. However, the issue still be there.

I tried to do with logLevel: config.LOG_DISABLE in karma.conf.js file. The workaround works for me. But I'm not sure this is a good way.

[dignifiedquire]

Could you file a new issue please, and post the full log with logLevel: config.LOG_DEBUG please?

Hi,

I can see this has been closed as fixed but the issue still seems to exist.

These are my devDependencies:

  "devDependencies": {
    "babelify": "^6.1.2",
    "browserify": "^10.2.4",
    "browserify-istanbul": "^0.2.1",

And this is my config:

    browsers: [ 'PhantomJS' ],

    files: [
      //'src/**/!(main).js',
      'src/dependencies.js',

    frameworks: [ 'jasmine', 'browserify', 'phantomjs-shim' ],

    logLevel: config.LOG_INFO, //config.LOG_DEBUG

    preprocessors: {
      'src/**/*.js': [ 'browserify', 'coverage' ],
      'test/**/*.tests.js': [ 'browserify' ]
    },

    // browserify configuration
    browserify: {
      debug: true,
      transform: [
        ['babelify', { sourceMaps: false, stage: 3 }],

      ],
    }
  });
};

I'm on Windows in case that's relevant... Locking the dependency for karma-coverage to 0.2.6 did not work for me unfortunately.

I found this issue: https://github.com/deepsweet/istanbul-instrumenter-loader/issues/32#issuecomment-249400313

Pinning to "instanbul-instrumenter-loader" : "0.2.0" fixed the issue for me.
