when I run karma start. “react”: “^16.1.0” “react-dom”: “^16.1.0” “react-test-renderer”: “^16.1.0”

I wonder if any can give us a clue on how to resolve this issue. Thanks

I bypassed test/index.js. Just went for the test files directly. I followed this link https://github.com/webpack-contrib/karma-webpack and got the tests passing. @ljharb very similar idea to your suggestion above. Added the code below to my karma.config.

    preprocessors: {
      'test/*_test.js': [ 'webpack' ],
      'test/**/*_test.js': [ 'webpack' ]
    },

    files: [{ pattern: 'test/*_test.js', watched: false }, { pattern: 'test/**/*_test.js', watched: false }],

Hi @ljharb, I set up the pattern { pattern: ‘test/**/*.json’, included: false, served: true} but still the error above persists. However, while running karma start all dependencies are built except one

./~/enzyme-adapter-react-16/build/ReactSixteenAdapter.js 92.1 kB {0} [built] [1 error]

I did not spotted this earlier. I guess this causes the error in the title of this post. Thank you for your help
