Mutation Testing

We will use Mutate++ to play around.

Preparation

1. git clone git@github.com:nlohmann/mutate_cpp.git && cd mutate_cpp
2. Follow the installation steps, namely:

• Create and activate a new virtual environment for the python install, I use pyenv for that
• In requirements.txt, replace all ">=" by "==", it will save some time adapting some scripts
• pip install -r requirements.txt
• python3 db_create.py

3. cd ..
4. Get the example project: git clone https://github.com/bast/cmake-example.git && cd cmake-example
5. Install the necessary package to build it: sudo apt install -y build-essential cmake
6. In CMakeList.txt, line 5, remove Fortran from the supported languages (unless you have a compiler for it installed)
7. Check that it builds:

• mkdir build && cd build
• cmake ..
• make

8. Run the tests: ctest, it should all pass

Usage

1. In the mutate_cpp folder, start Mutate++: python3 run.py
2. Open the app in your browser with the URL http://127.0.0.1:5000.
3. Follow the tutorial in mutate_cpp, just adapt the path to the source and build folders
4. Try with another project that you can build locally
