import { asserts } from "https://dotland.deno.dev/x/pagic@v1.6.3/deps.ts";
const { assertRejects } = asserts;
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.
Parameters
optional
ErrorClass: Constructor
