covr-package: covr: Test coverage for packages

Description Details Author(s) See Also


covr tracks and reports code coverage for your package and (optionally) upload the results to a coverage service like 'Codecov' or 'Coveralls' 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.


A coverage report can be used to inspect coverage for each line in your package. Using report() requires the additional dependencies DT and htmltools.

# If run with no arguments `report()` implicitly calls `package_coverage()`
