This error is due to the below line in cmocka.h file,
/* Perform an unsigned cast to uintmax_t. */
#define cast_to_uintmax_type(value)
((uintmax_t)(value))

Is there a patch to solve this build issue? This build issue comes when I tried to build cmockalib.

When I visit the web url www.cmocka.org, I found the supported parameter types of function assert_int_equal are integers.
so I thought what if I want to compare two long integer datas.
I looked into the cmocka source code and found that actually function assert_int_equal supports LargestIntegralType which covers long integer.
so I suggest to use
void assert_int_equal (LargestIntegralType a, LargestIntegralType b) instead of void assert_int_equal (int a, int b) during introduce assert macros api on website www.cmocka.org to tell user what we exactly support?

For numerical applications we sometimes need to test if floating point numbers are correct.

two few useful functions are

int assert_double_close(double a, double b, double rtol, double atol);

int assert_double_allclose(double *a, double * b, int size, double rtol, double atol);

The behaviour of these functions can be modelled after the testing functions in numpy:

https://docs.scipy.org/doc/numpy-dev/reference/generated/numpy.testing.assert_allclose.html

I'd like to start working on a PR, if there are no other considerations that these functions were not included in cmocka.

While checking memory leaks, buffer overflows using test_free, test_malloc, etc getting segmentation fault in the following case.

• Mocked Dynamic Memory handling functions like below

#ifdef UNITTEST
    extern void* _test_malloc(const size_t size, const char* file, const int line);
    extern void* _test_calloc(size_t nmemb, const size_t size, const char* file, const int line);
    extern void* _test_realloc(void *ptr, const size_t size, const char* file, const int line);
    extern void _test_free(void *ptr, const char* file, const int line);

    #define malloc(size) _test_malloc(size, __FILE__, __LINE__)
    #define calloc(nmemb,size) _test_calloc(nmemb, size, __FILE__, __LINE__)
    #define realloc(ptr,size) _test_realloc(ptr, size, __FILE__, __LINE__)
    #define free(ptr) _test_free(ptr, __FILE__, __LINE__)
#endif

• Segmentation fault is thrown in the code when test_free tried to deallocate the memory allocated by strdup.
• Below is the Call stack when run through GDB

But when i have replaced strdup with custom strdup to do the same, its working perfectly, No SEG-FAULT been observed. It seems Cmocka is not tracking the memory block allocated by the strdup.

Work-Around:

• I can mock strdup with Custom implementation while running the Test case but looking for straight Forward solution.

Is there any mocking i missed or is it not yet supported by Cmocka ?

Hi guys,
I want to add the builder platform of cmocka to my project. how to build the arm64 library to OS? thanks~

This issue was reported by cppcheck 1.75.

Cmocka version 1.0.1

Coverity is reporting possible dereferencing of null pointer in _function_called. The variable expected_call is dereferenced although it appears that it may be NULL.

Coverity error reader_ _libs_test_cmocka_cmocka-src_src_cmocka.c.html.zip

I currently use 1.1.1 version here

could you please update the package/add versioning support?

Thanks

In our testing scripts, some CMOCKA group tests are called repeatedly (sometimes like 100+ times). This is making our Jenkins job fail with some tests having invalid JUNIT (xml) files [root of XML having nested testsuites tag]. Is there a way to workaround this issue? Any information in this area is greatly appreciated.
Failed XML file format:

?xml version="1.0" encoding="UTF-8" ?>

... so on

Is this the same project as https://gitlab.com/cmocka/cmocka/tree/master ?
If so, perhaps you replace the contents of README.md with a note saying that the project has moved.

Compiling on Ubuntu 16.04 following these steps:

$ git clone https://github.com/clibs/cmocka.git
$ mkdir -p cmocka/build
$ cd cmocka/build
$ cmake ../
$ make

The compilation is broken with a bunch of errors like this:

error: ISO C does not support ‘__FUNCTION__’ predefined identifier [-Wpedantic]

This repo is outdated for 3 years... Is this the proper cmoka repository?

How can I set up a test that uses multiple MPI processes using CMake and cmocka?
I did it for the sequential case but I'm not able to test with MPI

Hi!

I'm sorry if this is has an obvious answer, but I haven't played with C/C++ enough to know for sure; still learning. :)
Also sorry if this has an answer written somewhere; I can be a mole sometimes.

I'm running into an issue trying to setup cmocka for a project, using CMAKE, Ninja, and espressif; all for an ESP32. I'll share what I can, but some things are private for company reasons.

Some information that might help:

• Linux Kernel 6.8.0
• Pop!_OS 22.04 LTS (Ubuntu 22.04 derivative)
• cmake version 3.22.1
• GNU Make 4.3
• ninja 1.10.1
• ESP-IDF v4.4.7-92-g718cdd6c65

I run into this issue when trying to build:

CMake Error at CMakeLists.txt:16 (find_package):
  Could not find a configuration file for package "cmocka" that is compatible
  with requested version "1.1.5".

  The following configuration files were considered but not accepted:

    /usr/local/lib/cmake/cmocka/cmocka-config.cmake, version: 1.1.5 (64bit)

As you can see, I have compiled cmocka, and I have just taken it from the master branch; it compiled without issue.

I have the following CMakeList.txt:

# The following four lines of boilerplate have to be in your project's CMakeLists
# in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)

# (Not part of the boilerplate)
# This example uses an extra component for common functions such as Wi-Fi and Ethernet connection.
set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/protocol_examples_common main/esp-protocols-master/components/esp_modem main/components)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(ThisIsAProjectName)

# Add CMocka CMake modules
list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cmake/cmocka)

if (UNIT_TESTING)
    find_package(cmocka 1.1.5 REQUIRED)
    include(AddCMockaTest)
    add_subdirectory(tests)
endif()

Have I missed anything? Have I missed anything in the documentation? I can't seem to find anything about this.

If you need more information, please ask, and I'll supply it if I can.

Edit

I forgot, but I use a build script (simply called build.sh) to build a bin file, which looks like this:

#!/bin/bash

#/opt/esp/python_env/idf4.4_py3.8_env/bin/python -m pip install --upgrade idf-component-manager
~/.espressif/python_env/idf4.4_py3.10_env/bin/python -m pip install --upgrade idf-component-manager

echo Delete Build folder...
rm -r -f ./build

echo Version.txt contains version
cat ./version.txt

echo Running cmake...

hi,

when i tried to build the cmocka library i got the following error message

Is it possible to run unit tests on Oracle Pro*C code?

If it is possible,

• Should we run tests on the .pc file or the compiled .c file.
• Can anyone please explain the steps to do so?

I tried googling this with no results.

For example, creating a simple database connection and returning via cn.pc file as follows:

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<sqlca.h>

char *p="username/password@SID";

void main()
{  
    EXEC SQL CONNECT :p;

    if(sqlca.sqlcode==0)
    {  
       printf("Database connection successful to %s",p);
    }
    else
    {   printf("\n connection to  %s   failed ",p);
    }

}

How should a test_cn.c file be coded for this?

Dear cmocka expert:
because some tools depend on "cmocka" dependency in my environment, After installing cmocka tool, when i try to compile my build again, the error is shown as title. Could you help me solving this issue? thank you in advance.
