Code coverage is a metric which indicates the percentage of volume of your source code covered by your tests. It is
certainly a good idea to have code coverage reports generated as part of Continuous Integration – it allows you to keep track of quality of your tests or even set requirements for your builds to have a certain coverage.
Code coverage in Visual Studio is only available in the Enterprise edition. Fortunately, thanks to OpenCover you can still generate coverage reports even if you don’t have access to the Enterprise license.
