Use your system’s CMake and gcc to configure, compile, and test.


If your system already has compatible versions of CMake and gcc installed, the project can be configured and build locally.


  • CMake 3.5+
  • gcc
  • git (optional)


Install/Compile CppUTest

Your distribution may include CppUTest as a system package. You can use it to good effect for most tests. If you prefer to build your own version, read on.

I prefer to use a bleeding-edge build (after v3.8) to incorporate a bugfix for copiers and comparators. If you aren’t doing that, building from v3.8 should be fine.

$ git clone
$ cd cpputest/cpputest_build/
$ git checkout 2b45d38c5c3dd71447bfe0ae993786a6da898658
# Alter the CMake flags as you see fit.
$ cmake -DC++11=ON -DTESTS=OFF ..
$ make
$ sudo make install && sudo ldconfig

Test Build

Compiling unit tests is optional. For illustration, this project will compile tests by default.

Configure and Compile

Configure and compile as for a typical CMake project:

$ cd build_test/
$ cmake ../cpputest_intro
$ make

Run Tests

CMake will run all test suites with:

$ ctest
# or
$ make test

To run individual test executables, run:

# ./bin/<test_executable>
$ ./bin/test_cpputest_intro

I prefer to colorize the tests’ output with:

$ ./bin/test_cpputest_intro -c

Production Build

It is important to distinguish between test and production builds. Unit tests often override behavior of production code with mocks, custom functions, and memory leak checks.

Configure and Compile

Configure and compile in a different build directory to avoid conflicting with the test build:

$ cd build/
$ cmake ../cpputest_intro -DCOMPILE_TESTS=OFF
$ make

Run Production Code

This project illustrates unit testing on a library so there are no production executables to run.
