'lintr::expect_lint_free()' fails when run by goodpractice

[richelbilderbeek]

goodpractice is right, but I am having trouble getting a clean result of goodpractice.

If I have a minimal package with only this test:

test_that("Package style", {
  lintr::expect_lint_free()
})

Building on Travis CI passes fine.

However, when Travis script runs the next line, with the command goodpractice::gp(), I get
this log error message:

It is good practice to

  ✖ checking tests ... Running ‘testthat.R’ ERROR Running the tests in

I expect the goodpractice::gp() test to work on Travis. When I run it locally, it also just works.

I hope you enjoy my thorough bug report and I hope I can wish you good luck to fix this 👍
