Question

对于以下模拟：

class MockUI8CBuff : public UI8CBuff_I {
 public:
    MOCK_METHOD2(put, unsigned(const uint8_t* start, unsigned n));
};

以下测试片段

MockUI8CBuff BFO;

uint8_t arr[] = {1, 2, 3};

EXPECT_CALL(BFO, put(ElementsAreArray(arr, 3), 2))
    .WillOnce(Return(1));

我收到以下错误

为什么会出现此错误？以下作品：

EXPECT_CALL(BFO, put(Pointee(1), 2))
    .WillOnce(Return(1));

无法将指针与数组进行比较。您应该使用如下语法：

EXPECT_CALL(BFO, put(_, _))
    .With(Args<0,1>(ElementsAre(1, 2, 3)));   // ElementsAreArray can also be used

使用Array作为参数的预期方法调用
