emock's Issues

连续mock两个不同的类内普通方法，发现走的同一个will()

class BaseFoo {
public: 
    int GetValue() {return 10;}
    int GetValue2() {return 20;}
};

TEST(emockTest, test0)
{
    FooA fooA;
    BaseFoo baseFoo;
    EMOCK(&BaseFoo::GetValue2).stubs().will(returnValue(2));
    EMOCK(&BaseFoo::GetValue).stubs().will(returnValue(1));
    std::cout<<"=== emockTest: "<<baseFoo.GetValue2()<<" "<<baseFoo.GetValue()<<std::endl;
}

你好，我像上边这样写打印得到的是=== emockTest: 1 1
我的编译环境是Visual Studio 15 2017
使用的是c++ 11 的标准set(CMAKE_CXX_STANDARD 11)
我单步调试看了一下，调用函数时，

// \\include\\emock\\\HookMockObject.h
    template <typename RT>
    ChainableMockMethod<RT> invoke(const void* api) 
    {
      return ChainableMockMethod<RT>(getInvokable(api)); 
    }

这里的api每次都是同一个，都是最后用EMOCK设置的函数的地址。

单步调试时中间有几步提示加载的模块中为找到当前堆栈
然后就到EMOCK_API_HOOK_FUNCTOR_DEF(1);
后边就。。没太看懂，，我是希望找到invoke里的api是在哪传入的，为什么两次都传入相同的。
希望大佬帮忙看看，thanks。

在ARM LINUX上跑的时候报错非法指令

是不是当前使用的一些汇编不支持arm64？

mock 类成员函数失败（虚函数和普通成员函数都失败）

使用 msvc ，但是 win32 平台是好的），使用demo为给定demo，x64平台有问题

当测函数有多个参数时还可以指定出参吗？

比如测试函数 void function(int in1, int2, int &out1, int &out2)，可以分别指定出参out1 out2为某个值吗

While generating makefile this error occurs in windows. I guess sys/mman.h is not available for windows. Then how can I run emock in windows. Can anyone please tell the step by step procedure to get emock running? It would be helpful.

你好，请问mock普通成员函数为什么会崩溃？

1、我mock动态链接库dll中的普通函数总是会报异常。
emock语句可以正常执行。调用mock后的函数时报如下异常：
发生异常：W32/0xC0000005
Unhandled exception at 0x00007FF9B14677BB in XXX.exe: 0xC0000005: Access violation executing location 0x00007FF9B14677BB.
2、mock虚函数虽然没有异常，但是mock没有生效，还是走的mock前的函数流程。
请问这是什么原因呢？
感谢回复！

文档

有详细的使用配置文档和使用文档吗？另外简单看了一下代码结构，里面的python 脚本有何用处呀？

mockcpp 多线程使用mock函数时会报错

VS2019 MSVC x64场景下mock类的普通成员函数时会奔溃，不能成功，详情分析见描述

分析过程如下：
HookMockObject::method函数中api的地址为0x00007ff797a93680
JmpOnlyApiHookImpl结构体初始化时api地址为0x00007ff797a93680，stub地址为0x0000021cf1320000
进入JmpCodeImpl结构体初始化时，from地址0x00007ff797a93680， to地址为0x0000021cf1320000
使用(unsigned long)to - (unsigned long)from公式计算后的结果为FFFF 8225 5988 C980。这个数值明显大于unsigned int能存放的大小。
因此m_code中存放的计算数值已经不对了。

然后我又参考mockcpp的源代码，在JmpCodeImpl的构造函数中，修改为
#if BUILD_FOR_X64
::memcpy(m_code, jmpCodeTemplateLong, sizeof(jmpCodeTemplateLong));
set_jmp_code_long(m_code, from, to);
#elif BUILD_FOR_X86
::memcpy(m_code, jmpCodeTemplate, sizeof(jmpCodeTemplate));
set_jmp_code(m_code, from, to);
#endif
其中
const unsigned char jmpCodeTemplateLong[] =
{ 0xFF, 0x25, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };

inline void set_jmp_code_long(unsigned char base[], const void* from, const void* to)
{
(uintptr_t)(base + 6) = (uintptr_t)to;
}
这样处理后mock类的普通成员函数可以成功，但是类实例的成员变量地址被修改到了，导致类析构时奔溃。

mock的思路没有看懂，所以代码修改不动，还请指导一下。

MINGW64 NOT SUPPORT

有计划发布一个release版本么

当前只有master分支，没有打tag，没有版本号，项目引入需要填版本号。
请问有计划发布一个release版本么？

defined but not used [-Wunused-function]

1.问题现象
编译时出现如下报错：
emock/types/ValueHolder.h:54:13: warning: ‘emock::Constraint* emock::{anonymous}::constraint(const emock::Constraint*)’ defined but not used [-Wunused-function]
Constraint* constraint(const Constraint* c)
2.问题分析
在C程序中，如果定义了一个静态函数或变量，而没有去使用，编译时会有一个警告：
'at_wait_send_finish' defined but not used [-Wunused-function]，
当前报错是由于函数定义在 .h 头文件中，但是没有使用。
3.解决办法
把函数定义在 .cpp 源文件中
4.参考信息：
https://stackoverflow.com/questions/2845748/function-defined-but-not-used-warning-in-c
https://blog.csdn.net/hanhui22/article/details/108869744

如何把EMOCK之后的函数设置为不被MOCK的状态

我想在多个TEST中 mock同一个函数，但是mock的返回值结果是不一样的，例如如下代码，TEST-01设置fun返回值为1，TEST-02设置fun返回值为2. 我的运行结果是TEST-01是成功的，但是TEST-02是失败的。怎么样才能是TEST-02也成功吗？


int fun()
{
  return 0;
}

// Success
TEST(Demo, 01)
{
  EMOCK(fun)
    .expects(atLeast(1))
    .will(returnValue(1));

  EXPECT_EQ(1, fun());

}

// Fail, because 'fun' return value is 1. 
TEST(Demo, 02)
{
  EMOCK(fun)
    .expects(atLeast(1))
    .will(returnValue(2));
  
  EXPECT_EQ(2, fun());
}

how to use .after(const InvocationMockerNamespace& ns, const std::string& name)

if I have a mock like this:
EMOCK(&CLASS_NAME_A::FUNCTION_NAME_A).expects(once()).id("1");

how can i ref to it from another EMOCK?
EMOCK(&CLASS_NAME_B::FUNCTION_NAME_B).expects(once()).after(???, "1").will(ignoreReturnValue());

what should i fill for ???

请问常函数可以mock吗？

请问常函数可以mock吗？我mock常函数总是报语法不对。另外在wiki中的使用手册是不是看不到了？多谢回复。

emock/src/Trampoline.cpp line 135 logical error "unsigned long begin, end, last_end = 0;"

emock/src/Trampoline.cpp :
line 135 "last_end = 0;"
line 153 "last_end = end;"
when do line 130 while, the line 153's effect will be covered by line 135.
so line 135 should before line 130.

like this:
unsigned long begin, end, last_end = 0;
while(!feof(fp)) {
...

同一个函数在目标被测函数中多次调用(会有不同结果)该如何mock？

如何在同一个用例中mock同一个函数多次，并且期望的行为每次都不同？
例如下面的示例：

class a {
public:
    int aFunc(int i) {
        // do something, return different value
        // or read differen value from file...
    }
};

class call {
public:
    int call_aFunc(int x) {
        int ret = 0;
        if (x==y) {
            ret = x * aobj.aFunc(x);  // expect return 2
        } else if (x%y==0) {
            ret = x % aobj.aFunc(x);  // expect return 10
            rer += y*aobj.aFunc(y);   // expect return 6
        } else if (x/y) {
            rer += y/aobj.aFunc(y);   // expect return 8
        } else {
            rer += aobj.aFunc(x);   // expect return 0
        }
        return rer += aobj.aFunc(ret);   // expect return 666
    }
a aobj;
int y;
};

mockcpp中有类似的语法：
.stubs().will(returnValue(10)).then(returnValue(6)).then(returnVaule(666));

emock也支持类似的语法，但是实测then没效果，每次返回的都是will中设定的10.

系统：Linux x86_64，编译器：g++

请问下如何恢复打桩前？

发现
EMOCK(&Foo::bar1)
.stubs()
.will(returnValue(1));
后Foo::bar1就永远打桩成这样了。
我有个场景
先打桩跑一下，然后再恢复没打桩之前的状态继续跑。不知道如何操作。多谢
