@vitest/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.
import * as libCoverage from "@vitest/istanbul-lib-coverage";
const map = libCoverage.createCoverageMap(globalCoverageVar);
const 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
for (const f of map.files()) {
const fc = map.fileCoverageFor(f);
summary.merge(fc.toSummary());
}
console.log("Global summary", summary);
