如何在Java中使用Jupiter测试返回新实例的实用方法？

<dependencies>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-api</artifactId>
        <version>5.8.1</version>
        <scope>test</scope>
    </dependency>
</dependencies>

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

public class MyTest {
    @Test
    public void testNewInstance() {
        // 测试代码
    }
}

public class MyClass {
    public MyClass() {
        // 构造函数
    }
}

public class MyTest {
    @Test
    public void testNewInstance() {
        MyClass instance1 = new MyClass();
        MyClass instance2 = new MyClass();
        
        assertNotSame(instance1, instance2);
    }
}
