karma-mocha-reporter

Karma reporter plugin with mocha style logging.

How does it look like

Installation

The easiest way is to keep karma-mocha-reporter as a devDependency in your package.json.

{
  "devDependencies": {
    "karma": "^1.0.0",
    "karma-mocha-reporter": "^2.0.0"
  }
}

You can simply do it by:

$ npm install karma-mocha-reporter --save-dev

Configuration

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],

    // reporters configuration
    reporters: ['mocha']
  });
};

Options

colors

Type: Object | Boolean

Lets you overwrite the default colors. Possible values are all colors and background colors from chalk.

Possible Values:

Value | Description | Default ------ | ----------- | ------- success | success messages | green info | info messages | grey warning | warn messages | yellow error | error messages | red

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],

    // reporters configuration
    reporters: ['mocha'],

    // reporter options
    mochaReporter: {
      colors: {
        success: 'blue',
        info: 'bgGreen',
        warning: 'cyan',
        error: 'bgRed'
      },
      symbols: {
        success: '+',
        info: '#',
        warning: '!',
        error: 'x'
      }
    }
  });
};

To disable the colors please use the colors option in the karma config.

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],

    // reporters configuration
    reporters: ['mocha'],

    // disable colors
    colors: false
  });
};

symbols

Type: Object

Lets you overwrite the default symbols.

Possible Values:

Value | Description | Default ------ | ----------- | ------- success | success messages | ✔ info | info messages | ℹ warning | warn messages | ⚠ error | error messages | ✖

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],

    // reporters configuration
    reporters: ['mocha'],

    // reporter options
    mochaReporter: {
      symbols: {
        success: '+',
        info: '#',
        warning: '!',
        error: 'x'
      }
    }
  });
};

output

Type: String

Possible Values:

Value | Description ------ | ----------- full (default) | all output is printed to the console autowatch | first run will have the full output and the next runs just output the summary and errors in mocha style minimal | only the summary and errors are printed to the console in mocha style noFailures | the failure details are not logged

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],

    // reporters configuration
    reporters: ['mocha'],

    // reporter options
    mochaReporter: {
      output: 'autowatch'
    }
  });
};

showDiff

Type: String | Boolean

Shows a diff output. Is disabled by default. All credits to the contributors of mocha, since the diff logic is used from there and customized for this module.

Currently only works with karma-mocha >= v0.2.2 Not supported for karma-jasmine since the additional properties needed to render the diff are not supported in jasmine yet.

Possible Values:

Value | Description ------ | ----------- true | prints each diff in its own line, same as 'unified' 'unified' | prints each diff in its own line 'inline' | prints diffs inline

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['mocha', 'chai'],

    // reporters configuration
    reporters: ['mocha'],

    // reporter options
    mochaReporter: {
      showDiff: true
    }
  });
};

divider

Type: String

Default: 80 equals signs ('=')

The string to output between multiple test runs. Set to false or empty string to disable

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['jasmine'],

    // reporters configuration
    reporters: ['mocha'],

    // reporter options
    mochaReporter: {
      divider: ''
    }
  });
};

ignoreSkipped

Type: Boolean

Possible Values:

• false (default)
• true

When setting the ignoreSkipped flag to true, the reporter will ignore the skipped tests in the output and you will see only the tests that where really executed. The summary will still contain the number of skipped tests.

maxLogLines

Type: Number

Lets you set the maximum number of lines which are printed for a failure. The default value is 999. Helps to cut long stack traces. Set the value to -1 to disable stack traces.

printFirstSuccess

Type: Boolean

Possible Values:

• false (default)
• true

Prints the result of an it block after it is run in one browser. This options is useful when you have tests which are conditionally run in one browser only. Otherwise the result of the it block would not be printed because it was not run in all browsers.

// testfile.spec.js
if (navigator.userAgent.match(/firefox/i)) {
  describe('Firefox tests', function() {
    it('this would only be reported when printFirstSuccess is true', function() {
      console.log('firefox test');
    });
  });
}

describe('Other tests', function() {
  it('this should be always reported', function() {
    console.log('hello world');
  });
});
