未加载错误配置-ReactJS测试用例

Question

我已经为组件中的功能编写了一个测试方案，该方案处理的是单击按钮。在运行测试时，出现错误

**Error      Config not loaded thrown**

这是我的测试用例

it('should dispatch handleForwardTranslation', (done) => {
        const mockStore = configureMockStore();
        const storeData = {
          dispatch: () => {},
          translator : initialState.translator
        };
        const store = mockStore(storeData);
        const spy = jest.fn();
        store.dispatch = spy;
        const wrapper = shallow(<COAForwardTranslations store={store} />).dive();
        wrapper.update();

        wrapper.instance().handleForwardTranslation();

        expect(spy);
        done();
      });

在容器中看起来像这样。我还有其他功能都可以正常工作，但是此特定功能似乎引发了错误。

        class COAForwardTranslations extends Component
        {
            this.state = {
                    SegmentMapRequest : {
                    BranchCode: '',
                    GroupId: '',
                    GlCompanyCode: '',
                    GlAccount: '',
                    SourceMode: '',
                    SourceSystem: '',
                    JournalCategory: '',
                    EffectiveDate: ''
                }
          this.handleForwardTranslation = this.handleForwardTranslation.bind(this);
          handleForwardTranslation()
            {
                this.props.getForwardTranslation(this.state.SegmentMapRequest);
            }
    render()
        {
            return(
         <Button style ={{float:"right"}} bsStyle="primary"  onClick={this.handleForwardTranslation}>Translate</Button>
    )}
        }
export const mapStateToProps =(state) =>({
        segmentMapResponse: state.translator.segmentMapResponse
})

export const mapDispatchToProps = (dispatch)=>({
        getForwardTranslation: (SegmentMapRequest)=>{
            dispatch(getForwardTranslation(SegmentMapRequest));
    }
})
export default connect(mapStateToProps,mapDispatchToProps)(COAForwardTranslations);
