Here is my component code and unit test case for it test case is success but the code inside subscribe is not getting coverage

my component.ts file

getAllType() {
      this.typeRefService.getAllTypes().subscribe((data) => {
        this.types = data.associationTypes;
        if(this.types.length > 0) {
          this.showNoData = false;
        }else {
          this.showNoData = true;
        }
        for (let i = 0; i < this.types.length; i++) {
          this.checkboxItems[i] = false;
          this.codes[i] = this.types[i].code;
        }
        // //console.log(this.types);
      });
    }

my component.spec.ts file

     it('should call a service', () => {
    const associationType= {
      "code": "ALSO_BOUGHT",
      "description": "Product's that are also bought with the given product",
      "name": "string",
      "createdBy": "createuser",
      "modifiedBy": "modifyuser"
    }

   spyOn(component , 'getAllType').and.callThrough()

    service = fixture.debugElement.injector.get(AssociationTypeRefServiceService);//get your service
    // spyOn(service,'getAllTypes').and.callFake(()=>{
    //   return of([associationType])

    // })

    spyOn(service,'getAllTypes').and.returnValue(of(associationType))
    service.getAllTypes()
    console.log(service.getAllTypes())
    expect(service.getAllTypes).toHaveBeenCalledWith()
    
    expect(component.getAllType).toBeTruthy()
    expect(associationType.code).toEqual('ALSO_BOUGHT')

    //
  });

While running unit test it passes but the code inside subscribe((data) => { does not get coverage . What am i doing wrong ? i am using jasmine karma and angular8
