Jest React - 否则未采用路径

如何解决Jest React - 否则未采用路径

我正在尝试为此 React 组件添加测试覆盖率，并且当 if 语句之后没有 else 时，我在组件上收到此消息“未采用其他路径”。

下面是我的带有开玩笑警告的组件。有人可以帮忙介绍一下这部分吗？

function CustomerSatisfaction(props: FeedbackProps) {
  const [status,setStatus] = useState<
    'idle' | 'active' | 'pending' | 'success' | 'error'
  >('idle');
  const handleSubmit = useCallback(
    async (smileyType: string,options: Record<string,string>) => {
      setStatus('pending');

      try {
        const result = await fetchWithError(() => {
          setStatus('error');
        })('/pub/Feedback/Feedbacks','POST',{
          surveyType: 'service',smileyType,comments: options.comment,ratings: {
            clearness: options['customer_satisfaction.clear'],ease: options['customer_satisfaction.easy'],speed: options['customer_satisfaction.fast'],performance: options['customer_satisfaction.perf'],},pageUrl: window.location.href,serviceId: props.serviceId,productId: props.productId,});

        **(else path not taken)** if (result.success) {
          setStatus('success');
        }
      } catch (e) {
        setStatus('error');
      }
    },[],);

  return (
    <CustomerSatisfactionComponent
      i18n={props.i18n}
      status={status}
      onSubmit={handleSubmit}
    />
  );
}

解决方法

伙计们，如果有人遇到这个问题，这是我的情况的解决方案

it('should render failure state',async () => {
    const component = shallow(
      <CustomerSatisfaction
        i18n={() => ({})}
        serviceId="123"
        productId="123"
      />,);

    (fetchWithError as jest.Mock).mockReturnValue(
      jest.fn().mockResolvedValue({
        success: false,}),);
    const onSubmit: any =
      component.find(CustomerSatisfactionComponent).prop('onSubmit') ||
      (() => {});
    await onSubmit('test',{});
    expect(component).toMatchSnapshot();
  });
