ngMocks.globalMock

ngMocks.globalMock marks declarations, services and tokens to be mocked if they appear in kept modules during creating mock modules.

The best place to do that is in src/test.ts for jasmine or in src/setup-jest.ts / src/test-setup.ts for jest.

Let's mark the APP_URL token in order to be mocked in its kept modules.

src/test.ts

ngMocks.globalKeep(AppModule);
ngMocks.globalMock(APP_URL);
ngMocks.defaultMock(APP_URL, () => 'mock');

src/test.spec.ts

// ...
MockModule(AppModule);
// ...
const url = TestBed.inject(APP_URL);
// ...

The url is mock.

Runtime inject() dependencies

ngMocks.globalMock also marks tokens that are only discovered at runtime through Angular's inject() function. This avoids repeating the token in every MockBuilder call.

Configure the token once in src/test.ts, src/setup-jest.ts, or src/test-setup.ts:

ngMocks.globalMock(BASE_PATH);
ngMocks.defaultMock(BASE_PATH, () => '/api/test-path');

The configured value is then available whenever MockBuilder keeps a component, directive, or pipe that injects the token:

    ngMocks.defaultMock(BASE_PATH);

  beforeEach(() => MockBuilder(TargetComponent));

  it('uses the global default for a runtime inject token', () => {
    const fixture = MockRender(TargetComponent);

    expect(fixture.point.componentInstance.basePath).toEqual(
      '/api/test-path',
    );
  });
