Karma Helpful Reporter gives you a customizable report after you run your Karma tests.

The errors from failed tests are displayed hierarchically based on the test suite and nesting level. console.log() messages are output at the bottom below the test summary and grouped by browser.

Install with npm:

npm install --save-dev karma-helpful-reporter

Inside your karma.conf.js

• add require('karma-helpful-reporter') to the plugins array
• add 'helpful' to the reporters array

Optionally, add the helpfulReporter object with as many properties from the below set as you'd like.

• The listed properties' values are the default ones

// karma.conf.js
module.exports = function(config) {
  config.set({
    plugins: [ require('karma-helpful-reporter') ],
    reporters: [ 'helpful' ],

    // Optional reporter settings
    helpfulReporter: {
      animationStyle: 'braille',
      clearScreenBeforeEveryRun: false,
      hideBrowser: false,
      maxLogLines: 42,
