Dear maintainer(s),

With a recent upload of r-cran-testthat the autopkgtest of r-cran-s2 fails in testing when that autopkgtest is run with the binary packages of r-cran-testthat from unstable on i386. It passes when run with only packages from testing. In tabular form:

                       pass            fail
r-cran-testthat        from testing    3.2.3-1
r-cran-s2              from testing    1.1.7-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of r-cran-testthat to testing [1]. Due to the nature of this issue, I filed this bug report against both packages. Can you please investigate the situation and reassign the bug to the right package?
