//in my component i have 

{this.props.auth.isLoadding && 
   <p className='text-info positionMessage'>Is registring...</p>
}

//in my test i have 

it('should start a new component with set props', () => {
const props = {
    auth: {
        isAuth: false,
        isLoadding: false
    }
}
    const wrapper = shallow(<ScreensCreateAccount {...props}/>)

    wrapper.setProps({isLoadding: true})
    //here is code for testing if <p>...</p> appeared. how can i do this?
})

我的组件以开头this.props.auth.isLoadding = false，当将其更改为true时，html也随之更改，添加<p className='text-info positionMessage'>Is registring...</p>。我如何使用酶的浅层测试呢？
