In order to collect code coverage after running executable
file, generate *.gcda and *.gcno file that require by lcov tool
to generate code coverage report.

+### Code Coverage
+
+Host based Unit Tests will automatically i enable coverage data.
+This is primarily leveraged for pipeline builds, but this can be leveraged locally using the
+lcov linux tool, and parsed using the lcov_cobertura python tool. pycobertura is used to
+covert this coverage data to a human readable HTML file. These tools must be installed
+to parse code coverage.
+
+- Windows Prerequisite
+ ```bash
+ Download and install https://github.com/OpenCppCoverage/OpenCppCoverage/tags
+ pip install pycobertura
+ ```
+
+- Linux Prerequisite
+ ```bash
+ sudo apt-get install -y lcov
+ pip install lcov_cobertura
+ pip install pycobertura
+ ```
+
+During CI builds, use the ```CODE_COVERAGE=TRUE``` flag to generate the code coverage XML files,
+and additionally use the ```CC_HTML=TRUE``` flag to generate the HTML file. This will be generated
+in Build/coverage.html.

+There is currently no official guidance or support for code coverage when compiling
+in Visual Studio at this time.
