CMOCKA/CMAKE template

Purporse

• Streamline the setup of new C projects
• Make it easy to setup a develoment enviroment
• Allow TDD for embedded systems
• Provide easy LSP usage via compile_commands.json
• correctly use the CTEST command.
• Avoid having to setup ruby/ceedling with it's dependency hell

10 directories, 24 files

The actual code is all stored inside the src direcotry with any libs/submodules stored inside their own subdirectories.

The code we use to test stuff gets stored inside the dir "tests" in the projects root.

The compile_commands.json file in the project root is actaully a symlink to the generated compile_commands.json file inside the build directory. So if you notice your LSP isn't working correctly it probably means that you haven't ran cmake yet.

Running and building the project

# change into the build dir
cd ./build

# generate the make files and make everything.
cmake ../ -DUNIT_TESTING=ON; make all;

# Run the tests
ctest

Adding tests

To actually add tests to the project create a new directory inside the "tests" dir. From there it will need a source.c and CMAKELists.txt file.

You will also need to include it inside the tests/CMakeLists.txt file as well.

add_subdirectory(new_test)

RoadMap

Things I want to add in the future:

• Automatic module creation
• template generation
• header --> mocking
• report generation
• embedded specific scripts for common hardware items

##TDD stuff

• what does a struct typedef <name_struct> *struct actually mean?
