About

This package provides a skeleton for JS unit testing, coverage and mutation testing. The provided config assumes files to be tested match src/**/*.js and test specs match test/**/*.spec.js but it should be straight forward to add more globs to your config.

Installation

npm install --save-dev apc-test

NPM Scripts

Copy these scripts into your package.json file. They are used by the build in Travis (see below)

  "test": "npm run lint && nyc mocha",
  "lint": "eslint *.js test/**/*.js src/**/*.js",
  "coverage": "nyc report --reporter=text-lcov | coveralls",
  "stryker": "stryker run"

Git Ignore

Copy the following into your gitignore:

# Logs
npm-debug.log*
yarn-debug.log*
yarn-error.log*

# Coverage directory used by tools like istanbul
coverage

# nyc test coverage
.nyc_output

# Dependency directories
node_modules/

# Optional npm cache directory
.npm

# Stryker reports and cache
.stryker-tmp
reports

NYC Config

Copy the following into a .nycrc file:

{
  "include": [ "src/**/*.js" ],
  "all": true,
  "watermarks": {
    "lines": [ 90, 99 ],
    "functions": [ 90, 99 ],
    "branches": [ 90, 99 ],
    "statements": [ 90, 99 ]
  },
  "reporter": [ "clover", "text", "text-summary", "html", "cobertura", "lcov" ],
  "cache": true
}

Or copy it cp node_modules/apc-test/.nycrc .

Stryker Config

Add the following to a stryker.conf.js file:

module.exports = config => {
  config.set({
    files: [
      {
        pattern: 'src/**/*.js',
        mutated: true,
        included: true
      },
      'test/**/*.js'
    ],
    testRunner: 'mocha',
    mutator: 'javascript',
    transpilers: [],
    reporter: ['html', 'clear-text', 'progress'],
    testFramework: 'mocha',
    coverageAnalysis: 'perTest'
  })
}

Or copy it cp node_modules/apc-test/.stryker.conf.js .

Travis YML

Add the following to a .travis.yml file:

language: node_js
node_js:
  - 'lts/*'
  - 'node'
after_script:
# Optionally run stryker in CI, although this currently isn't reported
# - npm run stryker
  - npm run coverage

Or copy it cp node_modules/apc-test/.travis.yml .

README Badges

Add the badge images and links to the top of your markdown file:

[![NPM Package][npm-badge]][npm-link] [![License][license-badge]][license-link] [![Build Status][travis-badge]][travis-link] [![Coverage Status][coveralls-badge]][coveralls-link] [![Maintainability][cc-badge]][cc-link] [![Dependencies][dm-badge]][dm-link] [![Dev Dependencies][dmdev-badge]][dmdev-link] [![Greenkeeper badge][gk-badge]][gk-link]

Add the links somewhere else in your markdown file. Replacing my-org-name and my-module-name.

Setting up 3rd party services

These steps assume a public github repo and public npm module.

1. Publish to Github
2. Add to travis CI (may need to sync account first) - https://travis-ci.org/profile/
3. Add to coveralls - https://coveralls.io/repos/new
4. Add to code climate - https://codeclimate.com/github/repos/new
5. Add to greenkeeper - https://github.com/apps/greenkeeper/installations/new
6. Copy codeclimate token to travis
   • Get reporter id from CodeClimate / Project / Settings / Test Coverage
   • Add it to the Travis repo settings as CC_TEST_REPORTER_ID environment variables
7. Check all badge are working (NPM and license won't work yet)
8. Publish to NPM

APC Style

Recommended to be used with apc-style for linting of JS, SCSS and Pug files.
