Closes #244
The testthat helpers are sourced into the pkgload env, and these might depend on non-exported bindings. Sourcing the helpers by default when
export_all = FALSE
will cause unexpected behaviour in that case. This patch changes the default to matchexport_all
.In particular, this makes
devtools::run_examples()
more reliable.Ideally I'd make
export_all = FALSE, helpers = TRUE
an error, but I don't have a sense of how much of a breaking change that would be for devtools-based tools.
