function assertRejects
import { assertRejects } from "https://deno.land/x/dotenv@v3.2.0/test_deps.ts";

Executes a function which returns a promise, expecting it to throw or reject. If it does not, then it throws. An error class and a string that should be included in the error message can also be asserted. Or you can pass a callback which will be passed the error, usually to apply some custom assertions on it.
