酶：如何模拟作为道具传递的函数

Question

我正在用酶进行测试，但不知道如何模拟作为道具传递的功能。

it("should do not login when submit a user that not exist", () => {
        const mock = jest.fn(() => true);
        const wrapper = shallow(<HomeFormComponent form={{getFieldDecorator: () => mock()}}/>);
        wrapper.find(Form).simulate("submit", {
            preventDefault: () => {},
        });
        console.log(wrapper)
    });

一个错误。

TypeError: getFieldDecorator(...) is not a function

在我的index.js中

      render() {
      const { getFieldDecorator } = this.props.form;
      }
      return (<FormItemContainer>
            {getFieldDecorator("password", {
              rules: [
                { required: true, message: "Please input your Password!" }
              ]
            })(
              <Input
                prefix={
                  <Icon type="lock" style={{ color: "rgba(0,0,0,.25)" }} />
                }
                type="password"
                placeholder="Password"
              />
            )}
          </FormItemContainer>)

这行得通吗？

const mock = jest.fn();
const wrapper = shallow(<HomeFormComponent form={{getFieldDecorator: mock}}/>);
