Found this today, when my CI alarmed to me (there I use vue-cli 3.0.0-rc.3). In production we still use hardcode versions of packages in packege.json (for example "@vue/cli-service": "3.0.0-rc.3"), so, as I think, it may be reproduced in many previous releases

Had the same problem after updating to 3.0.0-rc.7. Setting "testURL": "http://localhost/" in Jest config helped. Here's a related question from Stack Overflow: https://stackoverflow.com/questions/51554366/npm-test-fail-with-jest

@epiphone thanks! This work!

Relevant upstream issue in Jest and JSDOM:

• JSDom 11.12 causes SecurityError: localStorage is not available for opaque origins jestjs/jest#6766
• jest : SecurityError: localStorage is not available for opaque origins jsdom/jsdom#2304

If you are using jsdom, make sure you include url in jsdom configuration

const dom = new JSDOM(``, {
url: "https://example.org/",
});
