How to run a package's testthat tests

  • A+

For a given installed package, how do I run its testthat tests? I'm not a developer of the installed package, I'm a user. I just want to run its test suite to confirm its tests pass in my environment. I've tried test_check and test_package but I see errors.

To be more specific, I know its test suite fails and I want to run the tests in an interactive R session so I can debug it.

R doesn't install the testthat tests by default. To do so try :

install.packages('eplusr', INSTALL_opts="--install-tests", type='source') 

Then, either:


or alternatively using the built-in testInstalledPackage:
