Angular 无法覆盖MockStore

我使用provideMockStore对多个选择器进行单元测试。我需要覆盖其中一个测试用例的MockStore。代码如下。它没有覆盖存储。我在那里看过文档，其中提到mockStore=TestBed.inject（mockStore）。它抛出读取“类型“TestBedStatic”上不存在属性“inject”的错误 “@angular/cli”：“~8.2.1”， “@ngrx/core”：“^1.2.0”， “@ngrx/effects”：“^8.2.0”， “@ngrx/entity”：“^8.2.0”， “@ngrx/路由器存储”：“^8.2.0”， “@ngrx/schematics”：“^8.2.0”， “@ngrx/store”：“^8.2.0”

TestBed.inject

是一个角度9函数

对于angular 8，请使用

TestBed.get

谢谢您的回复。我尝试了mockedStore=TestBed.get（MockStore）；但出现了一个错误：NullInjectorError:没有MockStore的提供程序！您无法从v8中的

TestBed

获取

MockStore

（这是一个bug）。您必须获取存储并将其强制转换到MockStore.TestBed.get（存储）作为Mockstore@timdeschryver这个问题有没有被追踪到？@ChrisPaton
