Angular ngrx test with jest throw error ` console.error node_modules/jsdom/lib/jsdom/virtual-console.js:29`


I do the testing for my ngrx/store with jestjs. i got the testing passing result. eventhough getting an error like:

console.error node_modules/jsdom/lib/jsdom/virtual-console.js:29
    Error: Cross origin http://localhost forbidden

Any one help me to understand this above issue? and how to solve it?

Thanks in advance.

UPDATE: as per Luctia suggession i fixed the cors issue. but getting an error like:

Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.Error: Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.

      at mapper (node_modules/jest-jasmine2/build/queueRunner.js:25:45)

need to add any workaround for this?


Solution

  • Seems like you're using the store and effects for the test. I'm going to assume the effect will make an http request, causing this issue.

    That's why I would encourage to mock the service:

    {
      provide: GoogleBooksService,
      useValue: { searchBooks: jest.fn() },
    }
    

    See the NgRx Example App for an example.
