java无法使用TestNG和JMockit注入@Test注释的方法

Question

基本上，我想检查test（）函数是否调用静态方法JOptionPane.showInputDialog("Enter a string.")。这就是我迄今为止所取得的成就

使用的库：

1. TestNG 7.4.0
2. JMockit 1.49

当前测试代码：

package com.example;

import javax.swing.*;
import org.testng.annotations.Test;
import mockit.Mocked;
import mockit.Verifications;

public class Activity1Test {
    @Test
    public void shouldShowInputDialogOnUpdateTextButtonClick(@Mocked JOptionPane jOptionPane) {
        Activity1 activity1 = new Activity1();
        activity1.test();

        new Verifications() {{ JOptionPane.showInputDialog("Enter a string."); }};
    }
}

test（）函数：

public void test() {
    JOptionPane.showInputDialog("Enter a string.");
}

不幸的是，它给了我这个错误：
