Easier unit tests and better examples with exampletestr and covr
Nolan R., Padilla-Parra S.
<ns4:p>In spite of the utility of unit tests, most R package developers do not write them. <ns4:italic>exampletestr</ns4:italic> makes it easier to <ns4:italic>start</ns4:italic> writing unit tests by creating shells/skeletons of unit tests based on the examples in the user's package documentation. When completed, these unit tests test whether said examples run <ns4:italic>correctly</ns4:italic>. By combining the functionality of <ns4:italic>exampletestr</ns4:italic> with that of <ns4:italic>covr</ns4:italic>, having ensured that their examples adequately demonstrate the features of their package, the developer can have much of the work of constructing a comprehensive set of unit tests done for them.</ns4:p>
