When I want to run my project with the command npm run test
, I get the error below. What is causing this?
FAIL
● Test suite failed to run
SecurityError: localStorage is not available for opaque origins at Window.get localStorage [as localStorage] (node_modules/jsdom/lib/jsdom/browser/Window.js:257:15)

In case, if you are accessing your application with a http://localhost
prefix, you need to update your jest configuration (in your jest.config.js
) as,
"jest": {
"verbose": true,
"testURL": "http://localhost/"
}
In case you do not already have any jest configuration, just include the configuration in your package.json
. For example:
{
"name": "...",
"description": "...",
...
"jest": {
"verbose": true,
"testURL": "http://localhost/"
}
}
or in jest.config.js
:
module.exports = {
verbose: true,
testURL: "http://localhost/",
...
}
or if you have projects
configured:
module.exports = {
verbose: true,
projects: [{
runner: 'jest-runner',
testURL: "http://localhost/",
// ...
}]
}
