Two C/C++ testing tools, mockcpp and testngpp.

	mockcpp --- A C/C++ Mock Framework
	-------------------------------------
	https://github.com/sinojelly/mockcpp
	https://gitee.com/sinojelly/mockcpp

mockcpp is a jmock-like generic C/C++ Mock Framework, which doesn't use complex template technique which will result in very heavy compiling overhead.

C/C++ test framework

This project provided two tools for C/C++ testing.

Name	Description	Path
mockcpp	C/C++ mock framework	mockcpp
testngpp	C/C++ test framework	mockcpp/tests/3rdparty/testngpp

The sample project to use these tools is at :
https://gitee.com/sinojelly/testngpp-mockcpp-sample

You can use mockcpp with other C/C++ test framework, such as gtest, Catch2, CppUTest etc. The sample projects are at:
https://gitee.com/sinojelly/gtest-with-mockcpp
https://gitee.com/sinojelly/catch2-with-mockcpp

You can use mockcpp testngpp prebuilt libraries and header files, or use their source code.

If you use the prebuilt libraries, be sure they are built on the same os and compiler as the project that is being tested.

mockcpp features

OS	Compiler	Virtual method mock	Global function mock	Overloaded function mock

mockcpp's Issues

VS2010 error C4519: default template arguments are only allowed on a class template

系统：win10
IDE：VS2010
版本：master版本/2.7分支

Cmake选择VS2010后编译mockcpp通过，但是include到工程后，提示
“mockcpp/ChainingMockHelper.h(61): error C4519: default template arguments are only allowed on a class template”。
然后尝试使用mockcpp目录下的test确认下，也是cmake选择VS2010生成的工程，VS2010打开后，编译时同样报一样的错误：
“mockcpp/ChainingMockHelper.h(61): error C4519: default template arguments are only allowed on a class template”

ChainingMockHelper.h文件的61行是一个 "}"

template <typename V, typename D = std::default_delete<V>>
Constraint* eq(const V* val)
{
	return new IsEqual<std::unique_ptr<V, D> >(val);
} <-----line61

期望大佬回复

How can i mock nonvirtual member function?

i try to mock a nonvirtual member function, but it show me error like this:

unknown file: Failure
C++ exception with description "Virtual method address should be odd, please make sure the method long (Cfoobar::*)(long) is a virtual method" thrown in the test body.

i want to know below information:

1. Is mockcpp support mock nonvirtual member function?
2. if it's support, how can it do that?

// sample code
// mock target class---want to mock nonvirtual function: foobar_l
class Cfoobar {
public:
    Cfoobar() {}
    virtual ~Cfoobar() {}
    long foobar_l(long x) {return x;}
};
// unit test for this class
class CcallCfoobarByobj {
public:
    CcallCfoobarByobj() {}
    virtual ~CcallCfoobarByobj() {}
    Cfoobar cfoobar;
    long callfoobar_l(long x) {return cfoobar.foobar_l(x);}
};
// unit test case
TEST(verifyMockcpp, memberFunctionByObj_Mock) {
    MockObject<Cfoobar> mocker;
    MOCK_METHOD(mocker, foobar_l).stubs().will(returnValue(36));

    CcallCfoobarByobj obj;
    EXPECT_EQ(obj.callfoobar_l(2), 36);
    mocker.verify();
    EXPECT_EQ(obj.callfoobar_l(2), 2);
}

Can't work right under cygwin

What steps will reproduce the problem?
A simple one file teset:

#include <gtest/gtest.h>
#include <mockcpp/mockcpp.hpp>

void func()
{
    std::cout<<"In real func\n";
}

TEST(Test, should_call_func_once)
{
    MOCKER(func)
            .expects(once());
    func();
    GlobalMockObject::verify();
}

int main(int argc, char **argv) {
    testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

What is the expected output? What do you see instead?
I expect TEST pass, but I got:
[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from Test
[ RUN      ] Test.should_call_func_once

What version of the product are you using? On what operating system?
Windows XP, cygwin(gcc/g++ 4.5.3), gtest 1.6.0, mockcpp 2.6

Please provide any additional information below.

ProcStub may cause coredump when invoke a function be mocked concurrently

I found this problem in my job, to reproduce that problem, the simplified model is as follows:

int echo()
{
    return 0;
}

TEST(ProcStubTest, test1)
{
    MOCKER(echo)
        .stubs()
        .will(invoke(+[]{
            return 1;
        }));
    std::vector<std::thread> thds;
    for ( int i = 0; i < 4; i++ )
    {
        thds.emplace_back([]{
            for ( int i = 0; i < 100; i++ )
            {
                EXPECT_EQ(1, echo());
            }
        });
    }
    for ( auto&& t : thds )
    {
        t.join();
    }
    GlobalMockObject::verify();
}

problem:
when invoke the function be mocked concurrently，the operator= of result (member of ProcStub object) will be invoked concurrently, however, it's not thread safe, may cause double free/accessing freed memory etc..

In order to test my conclusion, I add a mutex for ProcStub as follows:

MOCKCPP_NS_START

        .stubs()
        .will(invoke_thread_safe(+[]{
            return 1;
        }));
    std::vector<std::thread> thds;
    for ( int i = 0; i < 4; i++ )
    {
        thds.emplace_back([]{
            for ( int i = 0; i < 100; i++ )
            {
                EXPECT_EQ(1, echo());
            }
        });
    }
    for ( auto&& t : thds )
    {
        t.join();
    }
    GlobalMockObject::verify();
}

It seems works and no longer cause coredump（although the implementation may not be so graceful）.

Compile error

What steps will reproduce the problem?
1. cmake
2. make fails, never got to "make install"

how can i mock overloaded template functions

i try to mock overloaded template functions：

template <typename M>
  void publish(const boost::shared_ptr<M>& message) const
{
  //do
}

template <typename M>
  void publish(const M& message) const
{
  //do
}

my code is :

MOCKER((void(ros::Publisher::*)(const map_service::MapChanged &))&ros::Publisher::publish<const map_service::MapChanged &>)
.stubs();

i want to mock the second template function, but it doesn't work.
Thanks for your help!

是否支持 apple clang 和 ndk clang?

移动平台上 c++使用也很广泛, 是否有相关说明?

怎么取消指定MOCKER

GlobalMockObject::verify(); 或者GlobalMockObject::reset();可以取消所有的MOCKER，但是，如果我想保留一部分MOCKER，只取消另一部分MOCKER，需要怎么做？

while running in linux multi-thread, maybe have coredump

sample test code:
`#include <stdio.h>
#include <pthread.h>
#include <sys/syscall.h>
#include <unistd.h>
#include "gtest/gtest.h"
#include "mockcpp/mokc.h"

int int_ret_func(int a, int b)
{
printf("call orginal function %s\n", FUNCTION);
return a + b;
}

int stub_int_ret_func(int a, int b)
{
int tid = (int)syscall(__NR_gettid);
printf("call stub function %s, tid: %d\n", FUNCTION, tid);
return a * b;
}

void void_ret_func(int a, int b, int c)
{
printf("call orginal function %s\n", FUNCTION);
}

void stub_void_ret_func(int a, int b, int c)
{
int tid = (int)syscall(__NR_gettid);
printf("call stub function %s, tid: %d\n", FUNCTION, tid);
}

void *threadFunc(void *arg)

while (1) {
int ret = int_ret_func(2, 3);
EXPECT_EQ(ret, 6);
void_ret_func(2, 3, 4);
usleep(1000);
}

return NULL;

}

TEST(TestSuite, Factorial_Stub)
{
MOCKER(int_ret_func).stubs().will(invoke(stub_int_ret_func));
MOCKER(void_ret_func).stubs().will(invoke(stub_void_ret_func));

#define TID_CNT 8
pthread_t tid[TID_CNT];
for (int loop = 0; loop < TID_CNT; loop++) {
    pthread_create(&tid[loop], NULL, &threadFunc, NULL);
}

for (int loop = 0; loop < TID_CNT; loop++) {
    pthread_join(tid[loop], NULL);
}

}`
running result:

because of data using after free, need to fix

EnglishManual mistake

The EnglishManual had a mistake:

    Output through pointer: outBound(point, constraint) 
should be
    Output through pointer: outBoundP(point, size, constraint) 

And it's better to add examples for outBound/outBoundP into EnglishManual.
I have many foreign follows using testngpp/mockcpp.

Thanks.

   CURRENT_DIR=$(cd `dirname $0`; pwd)
   INSTALL_PATH=~/test_tools/mockcpp_install 改为 INSTALL_PATH=${CURRENT_DIR}/../3rd/mockcpp
   XUNIT_NAME=testngpp 改为 #XUNIT_NAME=testngpp
   #XUNIT_NAME=gtest 改为 XUNIT_NAME=gtest
   #XUNIT_HOME=/usr/local 改为 XUNIT_HOME=${CURRENT_DIR}/../3rd/gtest
   修改 CMakeLists.txt 加上 set(CMAKE_CXX_STANDARD 14) 编译选项
   执行sh build_install.sh
5. 准备测试用例
   cd /tmp/gtest_mockcpp
   mkdir code && cd code
   vim CMakeLists.txt

Can not use MOCKER(malloc) to mock malloc

If you use MOCKER(malloc) to mock malloc function, it crash.

because mockcpp need malloc.

I think, maybe we can use MOCKABLE(malloc) to mock malloc.

But, we can't use MOCKER and MOCKABLE at the same time now.

2.7版本删除了以前版本提供的MOCKER_CPP宏？

int32_t func1Stub(Class1*o, int32_t in, int32_t &out)
{
    if (in >=1) {
        out = 1;
    } else {
        out = 0;
    }
    return 0;
}

MOCKER_CPP(&Class1::func1, int32_t (Class1::*)(int32_t, int32_t&)).defaults().will(invoke(func1Stub));

早期版本可以对类的普通函数这么打桩。在2.7版本中有什么替换方案？

Android Termux + Clang环境下 testngpp 有些so加载不成功。

使用 的 ltdl 动态库加载方式。
存在的问题如下：
1、有些库加载不成功。这是tesgngpp问题。参见图1.
2、虚接口mock问题。这是 mockcpp问题。参见图2.

mockcpp does not build against latest googletest 1.13

The main branch of mockcpp does not build against the latest version of googletest (v1.13 onwards) when specifying gtest as the unit test framework. The build fails when building ports/failure/gtest_report_failure.cpp.o because the included gtest.h forces an error with a message about the compiler being required to support C++14.

This was seen on Windows, using both cygwin and WSL Ubuntu.

This error occurs because the mockcpp build enforces c++11 compilation. The relevant code is in src/CMakeLists.txt::83:

IF(MSVC)
    ADD_DEFINITIONS(-DMSVC_VMG_ENABLED) #  /Z7)
    SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /vmg")
	INCLUDE_DIRECTORIES(BEFORE ${MOCKCPP_SRC_ROOT}/3rdparty/msinttypes)
ELSE(MSVC)
    ADD_DEFINITIONS(-std=c++11)
ENDIF(MSVC)

When the -std flag is removed, the latest version of googletest builds without problem.
Presumably the enforcing -std flag is there for a reason, but can it be either removed completely, or removed for gtest dependency?

Android Termux + Clang环境下mockcpp存在的问题

这个运行环境是比较少见的，mockcpp起初也没考虑这样的运行环境，它的很多特性跟编译器关系很大，所以会存在较多问题。
1、虚接口mock报错。mockcpp认为它可能不是虚接口。
2、ApiHook报错，Illegal Instruction.
3、InterfaceInfo测试不过，未抛出预期的异常。
4、格式相关测试有不通过的。

is change of license valid?

非常抱歉打扰作者， 我想确认下这个 mockcpp 从 GPL 切换到 MIT 是否有效， 按照社区的做法，似乎需要所有版权方、所有贡献者的授权才能收回 GPL license 的限制。

in Googletest, mockcpp throw C++ exception lead to subsequent testcase timeout

OS: Ubuntu 18.04
Compiler: Clang15.0.6
Googletest: Googletest 1.13.0
mockcpp: 2.7

func.c
int add(int a, int b){
return a+b;
}

func.h
int add(int a, int b);

mockcpp.cpp
#include "gtest/gtest.h"
#include "gmock/gmock.h"
#include "mockcpp/mockcpp.hpp"
extern "C" {
#include "func.h"
}

TEST(mockcpp, test_basic_add){
//This is a simple case to get mockcpp exception
MOCKER(add).expects(once()).with(eq(2),eq(2)).will(returnValue(4));
int ret;
ret = add(1,2);
EXPECT_EQ(ret, 3);
GlobalMockObject::verify();
}

TEST(mockcpp, test_basic_add_timeout){
int ret;
//time out when call mock object
ret = add(2,3);
EXPECT_EQ(ret, 5);
}

int main(int argc, char *argv[]) {
::testing::InitGoogleMock(&argc, argv);
return RUN_ALL_TESTS();
}

As the title says, mockcpp will throw an exception at the end of the test_basic_add case.
in this case, because there is no execution that matched argument function.
But in the next testcase, it will timeout when calling add, although we have called the verify() function

Observed from the debugger tool, it is stuck on mockcpp::ApiHookFunctor() ApiHookFunctor.h:168:1
-> std::mutex::lock

So I would like to ask if it is possible to provide a more comprehensive function than verify to clear all settings (including unlock mutex)
We can put it in the SetUp, so that each testcase has a clean environment
Or, is there any suitable solution to avoid this problem?

thanks

outBoundP 该怎么使用呢？大神们帮忙看看吧~！

最近项目中用到mockcpp当需要调用带有输出指针参数的函数时遇到问题，代码如下 ；

void function(int32_t *val)
{
}
int32_t expect = 10;
int32_t* bb = (int32_t*)malloc(sizeof(int32_t));
MOCKER(function).stubs().with(outBoundP(&expect, sizeof(expect)));
function(bb);
EXPECT_EQ(*bb, 10);
这里会在调用function时报错误 0xC0000005: 读取位置 0x0000000000007FF7 时发生访问冲突。
不知道这里到底怎么使用？ 环境windos10 +visual studio 2017 +mockcpp 2.6

怎么mock返回值是引用类型的函数

returnValue 只能指定返回值类型的， 感觉需要 returnRef

Compile error when using API Hook on Visual Studio 2019

The error information is:

mockcpp/ApiHookGenerator.h(52,34): error C2039:  'freeApiHook': is not a member of 'mockcpp::ApiHookFunctor<F,10>'

I think this issue may be related to the code below in https://github.com/sinojelly/mockcpp/blob/master/include/mockcpp/ApiHookFunctor.h

#if _MSC_VER >= 1920    // VS 2019 
#define MOCKCPP_API_HOOK_FUNCTOR_DEF(n) \
__MOCKCPP_API_HOOK_FUNCTOR_DEF(n, __stdcall)
#else
#define MOCKCPP_API_HOOK_FUNCTOR_DEF(n) \
__MOCKCPP_API_HOOK_FUNCTOR_DEF(n, ); \
__MOCKCPP_API_HOOK_FUNCTOR_DEF(n, __stdcall) 
#endif

Maybe some template features changed in Visual Studio 2019, so the code above must be modified to compile pass.
I just have modified it to pass the compilation, but not test using API hook tests (they crashed now, see #18 ).

Whether CMAKE_SOURCE_DIR can be changed to PROJECT_SOURCE_DIR?

mockcpp/src/CMakeLists.txt

Line 16 in 30e1bf9

SET(MOCKCPP_SRC_ROOT ${CMAKE_SOURCE_DIR})

When I compiled mockcpp in my test code directory, CMAKE_SOURCE_DIR points to my root directory, which leads to the wrong path at compile time.I suggest changing it to PROJECT_SOURCE_DIR.
My directory structure is as follows:

linux-jbfy:~/demo # tree
.
├── CMakeLists.txt          # CMAKE_SOURCE_DIR is "~/demo"
├── testcase                # my testcase folder
├── mockcpp
│   ├── CMakeLists.txt      # PROJECT_SOURCE_DIR is "~/demo/mockcpp"
│   ├── src
│   │   ├── CMakeLists.txt  # use CMAKE_SOURCE_DIR, and get wrong path"~/demo", should be "~/demo/mockcpp"
...

stubs() does not take effect

1、code
static int add(int left, int right)
{
return left + right;
}

TEST(ft_test, demo)
{
GlobalMockObject::reset();
MOCKER(add).stubs().with(any()).will(returnValue(300));
EXPECT_EQ(300, add(1, 4));
}

2、test result

3、googletest+mockcpp

MinGW 的 new/delete 行为，与其它有差异。
已经在 mem_checker/debug_new.cpp 中定义 NOT_USE_MEM_CHECKER 宏，避免 new/delete 重载导致问题。
还是遇到 delete mock对象出错。说明编译器确实在 delete 行为方面有差异。

MinGW GCC 8 compile error.

Maybe because the pointer is 8 bytes, not 4 bytes.

如何突破20个接口的限制呢？

outbound does not work when mock a member fucntion of a class with a output parameter

I want to use mockcpp to mock a member function of a class. The member function 
has a output parameter. I want to assign the value of the output parameter. but 
it doesnot work. Compilation can complete successfullly. But the output 
parameter is not assigned the mocked value. My code is below:

class Parameter
{
public:
int a;
Parameter() {a=0;}
}

class MyClass
{
public:
virtual void func(Parameter &b) { b.a = 1;}
}

Parameter p;
p.a = 2;
MockObject<MyClass> mocker;
MOCK_METHOD(mocker,  func ).stubs().with(outBound(p));

When MyClass::func is invoked, the output parameter p.a is not 2, but 1.

The API Hook actually modifies a few bytes at the entry of the function to a jmp instruction that jumps to another stub function. VS 2019 does not work in this way, probably because of adding a new protection to the code segment. If you have any information, you are welcome to provide clues or submit a PR.

API Hook 实际上是修改了代码段函数入口处的几个字节，把它改成了跳转到另外一个stub函数的jmp指令。VS 2019这种方式不可工作，可能是对代码段的修改增加了新的保护措施。如果有人了解相关信息，欢迎提供线索或者提交PR。

which kind of open source protocols do you complied with?

except for apache 2.0 ，there is something else ?

There is a link error if I use MOCKCPP_USE_MOCKABLE in my test project.

What steps will reproduce the problem?
1. Compile and install mockcpp in default configuration. 
2. Compile my test project, with /DMOCKCPP_USE_MOCKABLE.
3. (VS2005) Generation the following link error:
ut.obj : error LNK2001: "public: static class mockcpp::ChainableMockObject 
mockcpp::GlobalMockObject:

What version of the product are you using? On what operating system?
mockcpp 2.4, Windows XP and Visual Studio 2005.

Please provide any additional information below.
I think it may be better to provider a new cmake entry for 
MOCKCPP_USE_MOCKABLE.

How to returnStringvalue using MOCKER assertion?

Please leave a syntax example to returnStringValue using MOCKER assertion.
if not possible using MOCKER assertion if there is any other way please let me know with a sample example.

Does the ARM-Linux platform support it?

I cross-compiled the arm version library with the latest code, and the cross-compiler is gnu-6.5.0.
During the test, it is found that when the arm platform is running, coredump will be called by the function of mock.
The read function is the function of mockcpp piling.

Thank you for the answer!

why Mock does not work?

after i mock a c++ class function, my program still go into the function i mocked.
but, in the same folder, same CMakeLists.txt, another test_cpp file could mock successful.
my project folder like this:
a.cpp
{
b.func();
}
b.cpp
main.cpp
CMakeLists.txt
my test folder :
test_a.cpp
test_b.cpp
test_main.cpp
i want to use b.cpp's function in a.cpp, and i mock b.func in a.cpp for test a.func.

TestXXX.so.so not found issue

If use TestXXX.so in the command line, should remove .so in the name, ref to:sinojelly/test-ng-pp@c443925

仅参考上面一句话可能无法解决。此问题背景：
Linux上(A)已经编译了testngpp的二进制文件，直接放到另外一个Linux电脑(B)运行。
发现 TestXXX.so.so找不到。这可能有两个原因：
1、不支持 TestXXX.so 直接使用到命令行中，testngpp runner加载so的时候，再次追加一个 .so。（这种可能性小，因为B上直接源码编译testngpp，是可以运行的）
2、TestXXX.so 依赖于别的库，导致它加载失败，从而 testngpp runner 追加.so，再次尝试加载，还是失败。（这种情况就需要定位 TestXXX.so 为何加载失败，看起来它依赖于 libtestngpp.so 库，用的是本地路径，应该也是可以加载成功的）

如果命令行直接改成 TestXXX 名字，则看起来 so 加载成功了，但是 在 so 中找符号会失败：
test suite "libadder-ut-TestAdder" can't be loaded : libadder-ut-TestAdder.so: undefined symbol: _ZNK7mockcpp23ChainableMockObjectBase7getNameEv

with约束中 spy和check不能同时使用吗

bug: linux use large page memory, function stubs failed

mprotect for change function head instructions in memory.
current code use 4K size page, in normal machine should be OK;
but in large page (such as 2M size) mechine, mprotect system call return failed, because memory size not in bound.
so here gives a fix, read page size from kernel config, then set mprotect the right size.

单独取消mock的疑问

在mock过程中增加了许多接口的mock，但是无法单独取消某个接口mock，
使用verify()后会全部取消。
请问有没有办法在verify后，保留之前的mock内容？

bool checkGlobalEnable(void* vpIn)

原因分析

destructor 填充到虚表作为析构函数， 编译器调用析构函数，是约定析构函数不能外抛异常的，所以编译器直接省略了外层的 catch 语句，直接就走到了 std::terminate 上

建议方式

可以考虑直接测试 destructor 函数， 或者把 delete (Interface*) mock 语句封装成一个函数， 然后再断言， 即可正常工作

How does it work on VC, VS2003 ?

The function of _cxa_demangle cannot compile.

compile fail on platform that don't have cxxabi.h

What steps will reproduce the problem?
1. compile in qnx

What is the expected output? What do you see instead?
compile failed

What version of the product are you using? On what operating system?
latest version: mockcpp-2.5-20110326.rar 
platform: qnx

Please provide any additional information below.

3. compile mockcpp with cmake -DMOCKCPP_XUNIT=gtest 
-DMOCKCPP_XUNIT_HOME=/home/james/ExtDir/share/MockFramework/mockcpp-samples/tool
s/gtest 
-DCMAKE_INSTALL_PREFIX=/home/james/ExtDir/share/MockFramework/mockcpp/install ..
4. make install
4. cp install/lib/libmockcpp.a

What is the expected output? What do you see instead?
the result should be gtest's statistics, but the test program is exit, if there 
are some other test cases, maybe won't get invoked.

What version of the product are you using? On what operating system?

OutBound 类构造函数初始化值列表存在乱序

mockcpp/include/mockcpp/OutBound.h

Line 33 in 4c2b6d4

: ref(val), DecoratedConstraint(constraint)

应该先构造基类，后构造成员，当前会产生编译告警
