make-coverage-badge v1.2.0

make-coverage-badge

Create a coverage badge

Creates a code coverage badge like the following:

Currently just reads from Istanbul's JSON summary reporter and downloads a badge from https://shields.io/. Don't expect too much! Send a PR if you need configuration etc.

Usage

(For Create React Apps)

1. Configure Jest (in package.json):

"jest": {
  "coverageReporters": [
    "json-summary"
  ]
}

2. Run npm test -- --coverage
3. Run make-coverage-badge

Resulting badge will be in ./coverage/badge.svg.

Options

--output-path <path>

Writes the coverage badge to the given path (relative to project root). Defaults to ./coverage/badge.svg.

--report-path <path>

Path to a coverage report file. Defaults to ./coverage/coverage-summary.json.

Prior work

• Coveralls: paid for private repos
• coverage-badger: same approach, but using an XML report and therefore requires XML dependencies
