autotest_package() returns NULL

[joelnitta]

I am trying to use autotest_package() on my in-development package, but I'm not getting any results:

Congratulations @joelnitta, that is indeed exactly what the package is supposed to do when your package is in perfect working order, as explained at the end of this README section. NULL means all tests pass and behaved exactly as expected. Feel free to close, or even to submit a pull request with modified README text if you think it could be explained more clearly. Thanks!

[joelnitta]

Whoops, my bad for not reading the README thoroughly!

Though I think the behavior could perhaps be improved if it issued a message to the effect of "All tests passed" instead of NULL. There would be no doubt then... even for users who didn't read the README carefully enough 😅

What about a message like those issued by successful tests in testthat? (the random happy emoji is optional but welcome 😁)

[mpadge]

Great idea - I'll leave this issue open to implement it, or as said feel free to submit pull request. Thanks!

Is it ok if the result is literally "nothing" (empty line) .. ? In my case the result does not return NULL , however the var in the environment in RStudio indicates NULL , and the datatable output is empty. I assume the package is in "perfect working order" :), but I just want to be sure before going ahead (with ssr package) .. By the way, I do agree with @joelnitta that a message like "All tests passed" would be more informative and unambiguous

Thanks @schneiderpy. More work on autotest to come very soon, including addressing this issue. I don't know what you mean by "nothing" (some aspect of your RStudio configuration, i guess), but you shouldn't worry. The function always returns NULL when all checks are passed.
