I am trying to setup a Firebase Cloud Functions repo to run mocha test. However, it throws the following error when I use import * as firebase from "firebase-functions-test"; or const firebase = require("firebase-functions-test")();. You can see in my code that I haven't even called the actual firebase functions yet so I think this a setup issue.
Question: What change do I need to make mocha test running for Firebase Functions testing using import syntax?
Working test code
import { assert } from "chai";
describe("Sanity Check", () => {
it("should pass", () => {
assert.equal(0, 0);
});
});
Failed Test Code using require
const test = require("firebase-functions-test")();
import { assert } from "chai";
describe("Sanity Check", () => {
it("should pass", () => {
assert.equal(0, 0);
test.cleanup();
});
});
Failed code using import
import * as firebase from "firebase-functions-test";
import { assert } from "chai";
const test = firebase();
describe("Sanity Check", () => {
it("should pass", () => {
assert.equal(0, 0);
test.cleanup();
});
});
