Automated test demo

This is a minimal example that uses googletest and CMake in order to instrument the code with automated tests.

Some features

• CMake functionality for testing
• googletest framework as git submodule
• For Travis CI support see .travis.yaml file

Building with tests

cd <project_path>
git submodule update --init  # To checkout googletest

mkdir build
cd build
cmake ../
make
ctest

Some rationale for git submodule

In order to build this package you will need to checkout googletest which is necessary to compile the test source code. I have tried several approaches to googletest/gtest including OS package manager, git and ExternalProject of CMake. In my opinion the most reliable is to incorporate googletest as git submodule. External Project did require some configuration and had to che
