// asynchronously but the promise that it returns is not awaited by Karma.
// Coverage analysis begins when onRunComplete() is invoked, and output files
// are subsequently written to disk. For more information, see
// https://github.com/karma-runner/karma-coverage/blob/32acafa90ed621abd1df730edb44ae55a4009c2c/lib/reporter.js#L221
