Karma webpack compiled but not executed

I am running javascript tests with functionality compiled by webpack in Karma. It seems that sources are compiled but not processed by karma, no test run. testing.webpack.js

module.exports = {
  devtool: 'inline-source-map',
  resolve: {
    extensions: ['.js']
  },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: [/node_modules/],
        use: [{
          loader: 'babel-loader',
        }]
      }
    ]
  }
};

There is my karma.conf.js

const webpackConfig = require('./testing.webpack.js');
module.exports = function (config) {
    config.set({
        basePath: './',
        coverageReporter: {
            dir: 'tmp/coverage/',
            reporters: [
                { type: 'html', subdir: 'report-html' },
                { type: 'lcov', subdir: 'report-lcov' }
            ],
            instrumenterOptions: {
                istanbul: { noCompact: true }
            }
        },
        files: [
            'spec/**/*.spec.js'
        ],
        frameworks: ['should', 'jasmine', 'mocha'],
        reporters: ['mocha', 'coverage'],
        preprocessors: {
            'spec/**/*.spec.js': ['webpack', 'sourcemap']
        },
        plugins: [
            'karma-webpack',
            'karma-jasmine',
            'karma-mocha',
            'karma-should',
            'karma-coverage',
            'karma-chrome-launcher',
            'karma-phantomjs-launcher',
            'karma-mocha-reporter',
            'karma-sourcemap-loader'
        ],
        webpack: webpackConfig,
        webpackMiddleware: {
           stats: 'errors-only'
        }
    });

    return config;
};

I receive the following output:

    });
});

But no test run. I will be pleased with a tip. Thank you.

Previously when using the alpha version of karma-webpack 5, if you did not include 'webpack' as a framework in your karma configuration everything would build, but no tests would be run just like this. 5.0.0 stable has been released that addresses this issue and fixes that on the fly. If you update to that it should work fine.
