When tests are run generate a coverage report.
To access this coverage report mount any directory to /results in the
container. Coverage output files will be written to /results/coverage
w/in the container.
Later we can do other interesting things with the coverage detected
such as a test pass/fail criteria or submitted to a service such as
coveralls, etc.
