我有一个测试组件和一些需要观众使用不同模拟的测试。问题是我无法让观众在测试进行时动态更改它们。

基本上我有 2 个从 .json 文件导入的模拟，一个是正确的，另一个是有错误的。

正确：profitability-customer.json 无效：profitability-customer-JSON-error-1.json

在测试 8 中，我需要观众将模拟切换为无效的。

这是我所拥有的：

import * as reportMock from '@app/__mocks__/reports/profitability-customer.json';
import * as reportMockError from '@app/__mocks__/reports/profitability-customer-JSON-error-1.json';

let spectator: Spectator<ProfitabilityCustomerReportComponent>;

beforeEach(() => {
  spectator = createComponent(); 
  spectator.component.reportForm.controls.brands.setValue([testCustomer.brands[1].bkId]);
  testIter++;
});

createComponent = createComponentFactory({
    component: ProfitabilityCustomerReportComponent,
    imports: [SharedModule, HttpClientTestingModule, RouterTestingModule],
    providers: [MapService, DateSelectService,
      mockProvider(HeaderCustomerService, HeaderCustomerServiceMock),
      mockProvider(MapService, MapServiceMock),
      mockProvider(ReportingApiService, myFOO())
    ],
    shallow: false
  });

function myFOO() {
    let ReportingApiServiceMock: any;
    console.log(testIter);
    if (testIter === 8) {
      ReportingApiServiceMock = {
        getReport() {
          return of(reportMockError['profitability-customer-JSON-error-1']);
        }
      };
    } else {
      ReportingApiServiceMock = {
        getReport() {
          return of(reportMock['profitability-customer']);
        }
      };
    }

    return ReportingApiServiceMock;
  };
