Does karma has feature to read environmental variables in karma tests?

Can we read environmental variables in karma tests? If yes, can somebody let me know . process.env is not recognized in karma test.

The report names no file, test, or entry point; start by reproducing the process.env failure in a Karma test and inspect the project’s existing environment-handling documentation and tests. Done should mean a clear, supported way to read environment variables in Karma tests, with behavior documented and covered by a regression test.
