istanbul-lib-coverage

An API that provides a read-only view of coverage information with the ability to merge and summarize coverage info.

Supersedes object-utils and collector from the v0 istanbul API.

See the docs for the full API.

```js

var libCoverage = require('istanbul-lib-coverage'); var map = libCoverage.createCoverageMap(globalCoverageVar); var summary = libCoverage.createCoverageSummary();

// merge another coverage map into the one we created map.merge(otherCoverageMap);

// inspect and summarize all file coverage objects in the map map.files().forEach(function (f) { var fc = map.fileCoverageFor(f), s = fc.toSummary(); summary.merge(s); });

console.log('Global summary', summary);

```
