我有以下扩展Abstract类的类
public class MyConverter extends AbstractConverter<A, B> {
@Override
public B convert(A source) {
// implementation here
}
}
AbstractConverter
来自org.modelmapper
,其声明如下:
public abstract class AbstractConverter<S, D> implements Converter<S, D> {
...
}
现在,从使用Spock的Groovy文件中我想模拟我的类:
class ATestOverThere extends Specification {
def myConverter = Mock(MyConverter) // THIS THROWS THE EXCEPTION
...
}
但是我在初始化模拟时遇到了异常。

似乎我无法模拟使用Spock扩展抽象类的类,是吗?
答案 0 :(得分:1)
在类路径上除了CGLIB之外还有Objenesis,正如Michael Easter正确地说的那样,你的例子可行。不过,不需要使用ByteBuddy。
另请参阅Spock manual。
