karma-runscript-preprocessor

Runs a script on rebuild. Suitable to use on karma-webpack with a single test-loader file. The script execution can bail the test running if error happens, which is handy to run some checks even before the test run (e.g. jsxhint).

Installation

npm install karma-runscript-preprocessor --save-dev

Configuration

module.exports = function(config) {
  config.set({
    files: [
      'test-loader.js'
    ],

    preprocessors: {
      'test-loader.js': [ 'runscript', 'webpack' ]
    },
    runscript: {
      script: 'run-lint.sh', 'script, baseDir is your pwd'
      stopOnError: true, //on false it will not cancel the test run when script failed
      messageOnError: "(any message you want, even integration with CI)"
    }
};
