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 v8.stopCoverage() is invoked before the process exits.
