Coverage Badges     

Create coverage badges from different coverage reports.

Coverage badge examples:

Installation

yarn add --dev coverage-badges

or

npm install --save-dev coverage-badges

Configuration

Create .coveragebadgesrc file in JSON format.

Simple config example (for jest coverage)

.coveragebadgesrc example

{
  "source": "./coverage/coverage-summary.json",
  "attribute": "total.statements.pct"
}

packadge.json example

"scripts": {
    "premake-badge": "$(yarn bin)/jest --coverage",
    "make-badge": "$(yarn bin)/coverage-badges",
},
"jest": {
  "coverageReporters": [
      "text",
      "lcov",
      "json-summary"
    ],
}

Run

  yarn make-badge

This config creates a coverage badge in a default directory ./badges.

You can add ![Coverage](./badges/coverage.svg) to your README.md after the badge creation.

Advanced config example (using multiple coverage report from jest coverage and simplecov coverage for ruby)

},
"jest": {
  "coverageReporters": [
    "text",
    "lcov",
    "json-summary"
