找不到名称'provide‘

Question

当我使用Mock测试角度时，为什么找不到'provide‘。

​

 beforeEach(() => {

    TestBed.configureTestingModule({
      providers : [
      provide(StrategyTablesService,{useClass:MockstrategyService})
        ]
    });
  });

​

Answer 1

也许你必须使用一个对象provide来代替函数

beforeEach(() => {
  TestBed.configureTestingModule({
    providers: [{ 
      provide: StrategyTablesService, useClass: MockstrategyService }]
  });
});

Answer 2

您需要使用angular.mock.module()

beforeEach(() => {
  angular.mock.module(($provide) => {
    TestBed.configureTestingModule({
      providers: [
        $provide.value(StrategyTablesService, { useClass:MockstrategyService });
      ]
    });
  });
});
