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 enable coverage data.
+
+For Windows, This is primarily leverage for pipeline builds, but this can be leveraged locally using the
+OpenCppCoverage windows tool to parse coverage data to cobertura xml format.
+
+- Windows Prerequisite
+ ```bash
+ Download and install https://github.com/OpenCppCoverage/OpenCppCoverage/releases
+ python -m pip install --upgrade -r ./pip-requirements.txt
+ stuart_ci_build -c .pytool/CISettings.py -t NOOPT TOOL_CHAIN_TAG=VS2019 -p MdeModulePkg
+ Open Build/coverage.xml
+ ```
+
+ - How to see code coverage data on IDE Visual Studio
+ ```
+ Open Visual Studio VS2019 or above version
+ Click "Tools" -> "OpenCppCoverage Settings"
+ Fill your execute file into "Program to run:"
+ Click "Tools" -> "Run OpenCppCoverage"
+ ```
+
+
+For Linux, 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 to parse it to cobertura xml format.
+
+- Linux Prerequisite
+ ```bash
+ sudo apt-get install -y lcov
+ python -m pip install --upgrade -r ./pip-requirements.txt
+ stuart_ci_build -c .pytool/CISettings.py -t NOOPT TOOL_CHAIN_TAG=GCC5 -p MdeModulePkg
+ Open Build/coverage.xml
+ ```
+ - How to see code coverage data on IDE Visual Studio Code
+ ```
+ Download plugin "Coverage Gutters"
+ Press Hot Key "Ctrl + Shift + P" and click option "Coverage Gutters: Display Coverage"
+ ```

This works on both Windows and Linux but is currently limited to x64 architectures. Working on getting others, but we

For Windows add below tool for code coverage
1. OpenCppCoverage: parsing pdb file to generate coverage
data
2. pycobertura: show up html format data for coverage data
For Linux add below tool for code coverage
1. lcov: parsing gcda gcno file to generate coverage data
2. lcov-cobertura: convert coverage data to cobertura format
3. pycobertura: show up html format data for coverage data
