function takeCoverage

Usage in Deno

import { takeCoverage } from "node:v8";
takeCoverage(): void

The v8.takeCoverage() method allows the user to write the coverage started by NODE_V8_COVERAGE to disk on demand. This method can be invoked multiple times during the lifetime of the process. Each time the execution counter will be reset and a new coverage report will be written to the directory specified by NODE_V8_COVERAGE.

When the process is about to exit, one last coverage will still be written to disk unless stopCoverage is invoked before the process exits.

Return Type

void
