covr tracks and reports code coverage for your package and (optionally) upload the results to a coverage service like 'Codecov' http://codecov.io or 'Coveralls' http://coveralls.io. Code coverage is a measure of the amount of code being exercised by a set of tests. It is an indirect measure of test quality and completeness. This package is compatible with any testing methodology or framework and tracks coverage of both R code and compiled C/C++/FORTRAN code.
# If run with no arguments `report()` implicitly calls `package_coverage()` report()
