Mocha - Chai Karma "not defined"

Question

I am new to jscript tdd and got the problem, hope someone can show me what I'm doing worng. Running tests in a browser (via an HTML file) works fine. running them through node and karma, I got the following exception

I want to use Mocha and Chai in karma in the host node.js. I set through npm install [...] --save-dev mocha and karma mocha

I have a test library like this

suite('first suite', function () {
    test('SuccessTest', function () {
        expect(1).to.equal(1);
    });

    test('FailTest', function () {
        expect(1).to.equal(2);
    });
});

in node I used karma init to create a configuration file in which I set the framework for

frameworks: ['mocha','chai'],

now when i start karma he got this error

"not determined"

I assumed that declaring mocha and chai as a framework should have worked?

I also installed karma mocha and karma chay plugins in node.

How am I mistaken and what should I do?

, "chai" /, , , .

, "tdd" mocha ( "bdd" ):

// in config-mocha.js
window.mocha.setup({ui: 'tdd'});

"chai" :

module.exports = function(config) {
  config.set({
    files: [
      'path/to/chai.js',
      'config-mocha.js',
      // .. your source and test files
    ]
  });
};
