@liubko Yeah, this issue has come up very recently. More info here

[detj]

@liubko so, since npm run test uses the config/karma.config.js file, making the below modification makes the tests pass.

below sassLoader: webpackConfig.sassLoader, line, add

postcss : webpackConfig.postcss

And the tests will pass. This is no way a solution to this problem but at least this is help for someone who's trying this starter kit.

More insight is welcome. Thanks.

[davezuko]

Closing as originally resolved with @ptim 's comment, but postcss has now been removed with https://github.com/davezuko/react-redux-starter-kit/releases/tag/v3.0.0 in favor of utilizing css-loader options directly.
