PowerMock MockStatic 期望不适用于 EasyMock anyObject

Question

这似乎没问题

EasyMock.expect(URLDecoder.decode("test", "UTF-8")).andThrow(new UnsupportedEncodingException("This is a test"));

这不行

EasyMock.expect(URLDecoder.decode((String) EasyMock.anyObject(), "UTF-8")).andThrow(new UnsupportedEncodingException("This is a test"));

这将引发以下

java.lang.IllegalStateException: 2 matchers expected, 1 recorded.
This exception usually occurs when matchers are mixed with raw values when recording a  method:
foo(5, eq(6));  // wrong
You need to use no matcher at all or a matcher for every single param:
foo(eq(5), eq(6));  // right
foo(5, 6);  // also right

Answer 1

如果你打算在你的期望中使用 1 个匹配器，那么你需要使用所有匹配器。

可悲的是，这在您从 EasyMock 中得到的错误消息中没有得到很好的解释，但是在另一个字符串周围添加一个EasyMock.eq()应该可以解决问题。

EasyMock.expect(URLDecoder.decode((String) EasyMock.anyObject(), EasyMock.eq("UTF-8"))).andThrow(new UnsupportedEncodingException("This is a test"));
