Simple unit testing example with Check and CMake

This project is a complete C unit test with the Check library, using CMake as a build tool.

Status

Installing

To run this project the following programs need to be installed on your system:

Cmake
Check
Gcov
Lcov
Valgrind

Then, do as follows:

$ mkdir build && cd build
$ cmake ..
$ make
$ make test

Don't do make install unless you want to install the sample library.

sample.c and sample.h are built as a library. src/main.c:main() is a client of libsample.a, just as tests/test_sample.c:main().

After running make test, you will find the test files into Testing folder.

Code Coverage Support

This example implements Code Coverage Reports using either using either gcov or lcov. If you want to check them, you should run the following command after make test:

$ make gcov
$ make lcov

The coverage reports will be into Coverage folder. In the case of lcov, you can see into the browser, opening the index.html file on the folder above.

Valgrind Support

This example also implements a memory leak check with valgrind, thus allowing a full test of the application. If you want to check them, you should run the following command after make:

$ make test_sample_valgrind

It is important to note that, unlike code coverage generation, for each add_executable in the build, you will need to create a specific target for the valgrind with add_custom_target.

In the future, we plan to make a macro to simplify this task. At this moment, we only provide the means to add valgrind into build script.

Thanks

We have done our best to keep the code as simple as possible, both in the building scripts and in the test scripts, in order to be very straightforward and easy to understand.
