输入Jest单元测试：import React Component from react;import StyleSheet View Text Image AppState Linking from react-native;import BottomSheet from BottomSheet;import LColors from assetsStringsLColors;impor

这是一个使用Jest进行单元测试的示例代码。你可以使用Jest来测试React Native组件的各个功能和方法。

import React, { Component } from 'react';
import { StyleSheet, View, Text, Image, AppState, Linking } from 'react-native';
import BottomSheet from '../BottomSheet';
import LColors from '@assets/Strings/LColors';
import { bottomSpace, scaleSize, screenHeight } from '@utils/layout';
import { UIActivityIndicator } from 'react-native-indicators';
import { getList, doPayment, checkPay } from '@api/Order';
import ACTION_TYPE from '../Order/OrderAction';
import LTouchableOpacity from '../TouchAble/LTouchableOpacity';
import { aliPay, wxPay } from '@utils/native';
import TimerText from './TimerText';
import { Base64 } from 'js-base64';
import DialogContainer from '@common/UIComponents/Dialog/DialogContainer';
import { track } from '@utils/dataAnalytics';
import IconFont from '@assets/iconfont';
import LNumberText from 'imou-rn/dist/components/LNumberText';
import LToast from 'imou-rn/dist/components/LToast';
import { getImageUrlForPath } from '@utils/layout';
import LNetImage from '../LNetImage';
import { log, toast } from '@common/Utils/LogUtil';

export default class PayModal extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: null,
      selPayWayIndex: 0,
      time: '',
      isLoading: true,
      isNetError: false,
      leftTime: 10000,
      confirmModalVisible: true,
      appState: AppState.currentState,
      paymentId: '',
    };
    this.isGoToSuccess = false;
    this.onBack = this._handleBack.bind(this);
  }

  _handleAppStateChange(nextAppState) {
    if (
      this.state.appState &&
      this.state.appState.match(/inactive|background/) &&
      nextAppState === 'active'
    ) {
      this.doWhileGetPayResult();
    }
    this.setState({ appState: nextAppState });
  }

  doWhileGetPayResult() {
    const { paying, visible } = this.state;
    if (!paying || this.isChecking || !visible) return;
    this.isChecking = true
