You also need karma-babel-preprocessor to work with ES6 via Karma. https://github.com/babel/karma-babel-preprocessor

I forgot to put my test file

"use strict";

import BootstrapFormView    from "../src/js/views/BootstrapFormView.js";

describe("BootstrapFormView", function() {
    var bootstrapFormView = new BootstrapFormView();
  it("can convert error strings to errors", function() {
    var errorString = "|This is an error message";
    expect(bootstrapFormView.errorStringToErrors(errorString)).toBe("This is an error message");
  });
});

I installed karma-babel-preprocessor and added it to the plugging list and I still have the same issue.

I'm running into this issue too. Was there any resolution?

[xMarkusSpringerx]

I also have the same issue. Is there no solution out there?

[AlexisBarta]

Sorry guys I can't help much cause I'm using Webpack now.

[westonwatson]

I'm also having this issue. Anyone resolve this?

[kevincaradant]

@AlexisBarta I have also this error under Webpack with Karma :/, do you have to ? or did you have find a trick to fix it ? Thank you

[westonwatson]

@AlexisBarta using webpack and babel you should be able to transpile the ES6. preprocessors: { 'tests/jasmine/**/*.js': ['webpack','babel'] }
