|
|
|
|
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);
|
|
```
