Jest returns Error: secretOrPrivateKey must have a value after upgrade probot

Bug Report

Current Behavior
I update the probot to 11.0.5, and object { Application } = require("probot") is deprecated. I found the equivalent one { probot }.

When I run my unit test, it always returns "Error: secretOrPrivateKey must have a value". I have already mock-up the method I am going to test, how can I fix this error? Thank you.

Before I initialized the app from Application obj, it didn't require me to provide any credentials.

const { Probot } = require("probot");  //Used to be const { Application } = require("probot");
const plugin = require("..");
const pullRequestOpenedPayload = require("./fixtures/pull_request.opened.json");

describe("Size", () => {
  let probot;
  let octokit;

  beforeEach(async () => {
    probot = new Probot(); //Used to be  app = new Application()
    plugin(probot);

    octokit = {
      issues: {
        addLabels: jest.fn().mockReturnValue(Promise.resolve({})),
      },
    };
    probot.auth = () => Promise.resolve(octokit);
  });

  test("creates a label when a pull request is opened", async () => {
    await probot.receive({
      name: "pull_request.opened",
      payload: pullRequestOpenedPayload,
    });
    expect(octokit.issues.addLabels).toHaveBeenCalled();
  });
});

Environment

• Probot version(s): [e.g. 11.0.5]

I would recommend against mocking the octokit instance. If a future version renames the octokit.issues.addLabels method, your tests will still pass, but it will fail in production. I would mock the http requests instead, see https://probot.github.io/docs/testing/

I think new Probot() won't work, try new Probot({ githubToken: "test" }) instead
