如何创建用于单元测试的CellInfo对象？

import android.telephony.CellInfo;
import android.telephony.CellInfoCdma;
import android.telephony.CellSignalStrengthCdma;

public class CellInfoTest {

    public static void main(String[] args) {
        // 创建一个新的CellInfoCdma对象
        CellInfoCdma cellInfo = new CellInfoCdma();

        // 设置CellInfoCdma对象的属性
        cellInfo.setTimeStamp(System.currentTimeMillis());
        cellInfo.setCellIdentity(new CellIdentityCdma(123, 456, 789, 0));
        cellInfo.setCellSignalStrength(new CellSignalStrengthCdma(-70, -90, 0, 0));

        // 执行单元测试逻辑
        // ...

        System.out.println("CellInfoCdma created for unit testing: " + cellInfo.toString());
    }
}
