我一直在尝试使用 Mockito 模拟具有可变参数参数的方法:
I've been trying to get to mock a method with vararg parameters using Mockito:
interface A {
B b(int x, int y, C... c);
}
A a = mock(A.class);
B b = mock(B.class);
when(a.b(anyInt(), anyInt(), any(C[].class))).thenReturn(b);
assertEquals(b, a.b(1, 2));
这不起作用,但是如果我这样做:
This doesn't work, however if I do this instead:
when(a.b(anyInt(), anyInt())).thenReturn(b);
assertEquals(b, a.b(1, 2));
这可行,尽管我在存根方法时完全省略了可变参数参数.
This works, despite that I have completely omitted the varargs argument when stubbing the method.
有什么线索吗?
Mockito 1.8.1 引入 anyVararg() 匹配器:
Mockito 1.8.1 introduced anyVararg() matcher:
when(a.b(anyInt(), anyInt(), Matchers.<String>anyVararg())).thenReturn(b);
另请参阅历史记录:https://code.google.com/存档/p/mockito/issues/62
编辑弃用后的新语法:
when(a.b(anyInt(), anyInt(), ArgumentMatchers.<String>any())).thenReturn(b);
