cy.percySnapshot() crash Cypress if percy is not running

[MarosPistej]

Issue

If integration file contain cy.percySnapshot() but you are trying to run only Cypress (you are writing tests and don't want send snapshots to percy yet), when test reach cy.percySnapshot() it crash with unresolved Promise. Whole error in screenshot bellow.

Replication

1. build example project from https://github.com/percy/example-percy-cypress
2. modify package.json to start and open Cypress without percy cypress open instead of percy exec -- cypress open

"scripts": {
    "percy:cypress": "cypress open",
    "start:server": "serve -l 8000 .",
    "test": "start-server-and-test start:server 8000 percy:cypress"
  },

3. run npm test
4. in Cypress window select todo.spec.js to begin test
5. when Cypress reach cy.percySnapshot()at line 9 it crash
   

Known workaround

modify cypress/support/index.js file and include code bellow

import { isPercyEnabled } from "@percy/sdk-utils";
isPercyEnabled();

or

downgrade Cypress to version 6.4.0

Hey @MarosPistej Thanks for the issue! This is related to #315 & unfortunately external to Percy. I'll close this since it's a dupe of #315
