Ensure incremental coverage gains are not lost, and positively reinforce good testing habits. Automatically bump up global Jest thresholds whenever coverage goes above them.

- Conventional `jest.config.js` (`package.json` config unsupported)

- `json-summary` coverage report (see [usage](#usage))

jest-it-up exposes a standalone CLI tool (see [options](#options)), but you most likelly want to use it in a post-test script.

    "test": "jest --coverage", // or set `collectCoverage` to `true` in Jest config

    "posttest": "jest-it-up" // must run from the same directory as `jest.config.js`

    'json-summary' // plus any other reporters, e.g. "lcov", "text", "text-summary"

      branches: 0, // or your current numbers

Once tests finish running, jest-it-up will update configured thresholds to match higher coverage numbers, if any.
