[Question] Is there a way to view the webpack bundle that gets produced by running 'grunt karma'?

[gwevans]

I am getting an error while running grunt karma. I am using a the preprocessors key to bundle my tests into one bundle, from there I use phantomJS as my browser.

I am using

karma: {
    options: {
        preprocessors: {
             'test/testFile.js': ['webpack'],
        }
    }
}

Karma is failing due to 'unexpected token const', and points to line 9452 of testFile.js (ie the newly created bundle). This is clearly babel-loader related, and is coming from somewhere within node_modules, but I have no idea where. Is there a way to view the newly created bundle is created when running 'grunt karma'?

Run karma with --no-single-run http://karma-runner.github.io/2.0/config/configuration-file.html.
