Question

当我运行jest时，我遇到了包findNodeHandle react-native的问题。我的代码是这样的：

import { findNodeHandle, TextInput } from 'react-native';

export default class Input extends Component {
    componentDidMount() {
        findNodeHandle(this.refInput);
    }

    render() {
        return (
            <TextInput
                ref={ref => this.refInput = ref}
            />
        )
    }

当我运行开玩笑时，它会显示此错误：

    Invariant Violation: Unable to find node on an unmounted component.

at invariant (node_modules/react-native/node_modules/fbjs/lib/invariant.js:44:15)

at findNumericNodeHandleFiber (node_modules/react-native/Libraries/Renderer/ReactNativeFiber-dev.js:3250:14)

我想是在嘲笑包react-native并对待函数findNodeHandle，但我找不到一种方法来进行模拟。

我怎么解决这个问题？

react-native：49.5
开玩笑：21.2.1
