Angular Jasmine + Contentful: How to Test a Contentful call?


I’m using Contentful to load text into my Angular Singel Page Application. It works fine but now I want to test it. The test should actually call Contentful and load the text of myPage from my space. Then I want to assert that an expected value (the title field of myPage) is not null.
This way I want to make sure that calling Contentful works from my Frontend / SPA.

The code where I call Contentful is put inside a service called contentful.service.ts. This is the test that I tried for this service:


describe('ContentfulService', () => {
  let service: ContentfulService;

  beforeEach(() => {
    service = TestBed.inject(ContentfulService);

it('should get myPage for the default language en-US', (done) => {   
    service.getMyPage("en-US").then(myPage => {

This is my contentful.service.ts:

export class ContentfulService {
  private clientConsentPage = createClient({
    space: environment.contentfulConsent.spaceId,
    accessToken: environment.contentfulConsent.access_token,
    environment: environment.contentfulConsent.environment

constructor() { }

public getMyPage(locale: string): Promise<Entry<any>> {
    return this.clientConsentPage.getEntries(Object.assign({
      content_type: 'myPage'
    }, { '': environment.contentfulConsent.contentTypeIds.myPage, locale: locale }))
      .then(res => res.items[0]);

As I said this code works fine, only the test fails with either one of the following error:

TypeError: clientConsentPage.getEntries is not a function


Error: Timeout - Async function did not complete within 5000ms (set by jasmine.DEFAULT_TIMEOUT_INTERVAL)

(I don’t know why it’s not always the same error…)
