java - 使用 mockito 从 Object 模拟 BeanInfo 类

Question

假设我有以下方法结构：

protected static void sub(Object obj, String filler) {

    class cls = obj.getClass();
    BeanInfo beanInfo = Introspector.getBeanInfo(cls);

    // Other code...
}

给定这种结构，我如何模拟 BeanInfo 类？

Answer 1

将此逻辑移动到单独的方法：

static BeanInfo beanInfo(Object obj) {
    Class cls = obj.getClass();
    BeanInfo beanInfo = Introspector.getBeanInfo(cls);
}

然后模拟beanInfo方法。

Answer 2

You should code with dependency injection in mind. Then you can pass the mock as a parameter in your test.

protected static void sub(BeanInfo beanInfo, String filler) {
    // code...
}
