Run()后边没有写实现，是为了用宏定义将测试用例放入到 Run 的实现里，例如：
TEST(AddTestDemo)

EXPECT_EQ(3, Add(1, 2));

}
上述代码将 { EXPECT_EQ(3, Add(1, 2)); EXPECT_EQ(2, Add(1, 1)); } 接到 Run() 的后面

真假断言

/*
比较断言
EXPECT_EQ(v1, v2) 验证条件: v1 == v2
EXPECT_NE(v1, v2) 验证条件: v1 != v2
EXPECT_LT(v1, v2) 验证条件: v1 <  v2
EXPECT_LE(v1, v2) 验证条件: v1 <= v2
EXPECT_GT(v1, v2) 验证条件: v1 >  v2
EXPECT_GE(v1, v2) 验证条件: v1 >= v2

Note:
1. 参数应满足 EXPECT_*(Expect, Actual)的格式，左边是期望值，右边是实际值
2. 在断言失败时，会将期望值与实际值打印出来
3. 参数值必须是可通过断言的比较操作符进行比较的，参数值还必须支持 << 操作符来
将值输入到 ostream 中
4. 这些断言可以用于用户自定义型别，但必须重载相应的比较操作符（如 == 、< 等）
5. EXPECT_EQ 对指针进行的是地址比较。即比较的是它们是否指向相同的内存地址，
而不是它们指向的内容是否相等。如果想比较两个 C 字符串(const char*)的值，
请使用 EXPECT_STREQ 。特别一提的是，要验证一个 C 字符串是否为空(NULL)，
请使用 EXPECT_STREQ(NULL, c_str)。但是要比较两个 string 对象时，
应该使用 EXPECT_EQ

Example:
EXPECT_EQ(3, foo());
EXPECT_NE(NULL, pointer);
EXPECT_LT(len, v.size());

指针比较
EXPECT_PTR_EQ(p1, p2)            验证条件: *p1 == *p2
EXPECT_PTR_NE(p1, p2)            验证条件: *p1 != *p2
EXPECT_PTR_RANGE_EQ(p1, p2, len) 验证条件: 任意 i (*p1 + i) == (*p2 + i)  i∈[0,len)
EXPECT_PTR_RANGE_NE(p1, p2, len) 验证条件: 存在 i (*p1 + i) != (*p2 + i)  i∈[0,len)

Note:
1. 参数应满足 EXPECT_PTR_*(Expect, Actual)、
EXPECT_PTR_RANGE_*(Expect, Actual, len)的格式，
即参数表中期望值在实际值左边
2. EXPECT_PTR_EQ 比较的是指针所指元素的值，如果要比较
指针指向的地址是否相等，请用 EXPECT_EQ
3. EXPECT_PTR_RANGE_* 比较的是从 p1，p2 开始，
长度为 len 的区间，请确保区间长度有效

Example:
int a[] = {1,2,3,4,5};
int b[] = {1,2,3,4,6};
int *p1 = a, *p2 = b;
EXPECT_PTR_EQ(p1, p2);                      通过
p1 = a + 4, p2 = b + 4;
EXPECT_PTR_EQ(p1, p2);                      失败
EXPECT_PTR_EQ(p1, std::find(a, a + 5, 5));  通过
EXPECT_PTR_RANGE_EQ(a, b, 5);               失败

1. 容器可以是 STL 容器，自定义的容器，或者数组，但不可以是指针
2. 容器的数据类型要能够进行比较，类型一致或可以发生隐式转换
3. EXPECT_CON_EQ 测试失败时，会打印首次不相等的两个值
