Javascript 运行多个测试时，rxjs/redux可观察操作以错误的顺序调度

我正在为jasmine的redux可观察史诗写一些测试。当“单独”运行一个测试时（使用

fit（…）

），测试通过，但当与另一个测试结合运行时（使用

it（…）

），测试失败，因为操作的调度顺序错误。感谢您的帮助

这里有一些史诗，所以除非必要，否则我不会发布它们

这是（某种）测试文件：

const epicMiddleware = createEpicMiddleware(combinedEpics)
const mockStore = configureMockStore([epicMiddleware])

describe('my test', () => {
  let store

  beforeEach(() => {
    store = mockStore(...)
    jasmine.Ajax.install()
  })

  afterEach(() => {
    jasmine.Ajax.uninstall()
    epicMiddleware.replaceEpic(combinedEpics)
  })

  // test 1 passes
  it("test 1", () => {
    jasmine.Ajax.stubRequest("url-1").andReturn({
      status: 200,
      responseText: JSON.stringify({ ... })
    })

    store.dispatch(initializePage())

    expect(store.getActions()).toEqual([
      { type: INITIALIZE_PAGE },
      { type: MY_ACTION1 },
      { type: INITIALIZED_PAGE }
    ])
  })

  // test 2 passes with `fit` but not with `it` 
  it("test 2", () => {
    jasmine.Ajax.stubRequest("url-2").andReturn({
      status: 200,
      responseText: JSON.stringify({ ... })
    })

    store.dispatch(initializePage())

    expect(store.getActions()).toEqual([
      { type: INITIALIZE_PAGE },
      { type: MY_ACTION2 },
      { type: INITIALIZED_PAGE }
    ])
    /**
     * With `fit` the actions come in the order [INITIALIZE_PAGE, MY_ACTION2, INITIALIZED_PAGE]
     * With `it` the actions come in the order [INITIALIZE_PAGE, INITIALIZED_PAGE, MY_ACTION2]
     */
  })
})

事实证明，如果我在

beforeach

中创建

epicMidleware

而不是使用

epicMiddleware.replace（combinedEpics）

，它是有效的。像这样：

describe('my test', () => {
  let store
  let epicMiddleware
  let mockStore

  beforeEach(() => {
    epicMiddleware = createEpicMiddleware(combinedEpics)
    mockStore = configureMockStore([epicMiddleware])
    store = mockStore(...)
    jasmine.Ajax.install()
  })

  afterEach(() => {
    jasmine.Ajax.uninstall()
  })

  ...
