Questions tagged [cmockery]

Cmockery is a testing and mocking library for C.

Cmockery only requires linking with the C library; it does not require use of C++ or a C++ compiler or any advanced or recent features of the C language, thus making it portable and usable in many situations, e.g., testing embedded code.

Correct way to temporarily enable and disable function wrapping in cmocka?

I am using the cmocka library to test some embedded c code. According to the documentation I use the __wrap_ prefix to mock functions so I can isolate my unit tests. However once I do that all calls to the function forever go to the wrapped…

How do I tell gcc to relax its restrictions on typecasting when calling a C function from C++?

I'm trying to use Cmockery to mock C functions called from C++ code. Because the SUT is in C++, my tests need to be in C++. When I use the Cmockery expect_string() macro like this: expect_string(mock_function, url, "Foo"); I get: my_tests.cpp: In…

How do I work around the GCC "error: cast from ‘SourceLocation*’ to ‘int’ loses precision" error when compiling cmockery.c?

I need to add unit tests using Cmockery to an existing build environment that uses as hand-crafted Makefile. So I need to figure out how to build cmockery.c (without automake). When I run: g++ -DHAVE_CONFIG_H -DPIC -I ../cmockery-0.1.2 -I…
