WDIO v6 Compatibility

Installation

• NPM

npm install wdio-coverage-reporter --save-dev

reporters: [
  'dot',
  'coverage'
],

Configuration

This plugin is fetching the test coverage information after each test into .nyc_output.

• The page under test must be instrumented. Check NYC.
• The report must be generated with NYC, after the WDIO run.

An example with instrumented code and static server can be found in test/integration. Usually, the framework of your choice has already middleware for serving and instrumenting on the fly.

Example(please add more with PR):

• https://github.com/istanbuljs/babel-plugin-istanbul

{
"scripts": {
    "test": "npm run-script instrument && npm run-script wdio && nyc report",
    "instrument": "nyc instrument ./webapp ./dist --complete-copy --delete",
    "wdio": "npx wdio wdio.conf.js",
