grunt-not-constantinople v1.0.0

grunt-not-constantinople

Grunt task to easily add Istanbul code coverage using any unit-testing framework.

Getting Started

This plugin requires Grunt ~0.4.4 -- Learn to use Grunt

Install the plugin with this command:

npm install grunt-not-constantinople --save-dev

Enable in your Gruntfile with:

grunt.loadNpmTasks('grunt-not-constantinople');

Quick setup

grunt.initConfig({
  not_constantinople: {
    coverage: {
      options: {
        unitTestTask: 'mochaTest'
      }
    }
  },
  mochaTest: {
    test: {
      options: {
        reporter: 'spec'
      },
      src: ['tests/**/*.js']
    }
  },
});

This uses mochaTest as an example unit testing framework, but you can use any other framework instead. You just have to specify the task to be run as a string value for the unitTestTask option.

The "not_constantinople" task

Overview

In your project's Gruntfile, add a section named not_constantinople to the data object passed into grunt.initConfig().

grunt.initConfig({
  not_constantinople: {
    customized_coverage: {
      options: {
        // REQUIRED OPTION - This should be the task that runs your unit tests (e.g. 'mochaTest', 'nodeunit:myTests', etc.)
        unitTestTask: 'myUnitTestingTask',
        // directory names to be used for your tests and coverage
        directories: {
          root: 'test',
          coverage: 'coverage',
          sourceFiles: 'app/*.js'
        },
        // Coverage thresholds. Set to false to ignore thresholds
        thresholds: {
          statements: 90,
          branches: 90,
          lines: 90,
          functions: 90
        },
        // The format of the coverage reports
        report: {
          type: 'lcov',
          print: 'detail'
        },
        // removes the contents of the coverage folder before running Istanbul
        cleanup: true
      }
    }
  },
});
