Re: [R-pkg-devel] Is using global assignment in package tests allowed?

It may bear repeating that use of a test runner package is NOT required by CRAN Repo Policy, Writing R Extensions, or any other official text. If any one of these candidate packages is too complicated, or confusing, or lengthens your test setup, or [your reason here] then consider not using it. Choice is a good thing, and we have a free option of using one or none of the different available testing packages.

Re: [R-pkg-devel] Is using global assignment in package tests allowed?
I don't know the answer to your question, but "beyond my ken" doesn't sound like a very convincing reason. Mucking with any environment that isn't yours is asking for trouble... the behavior you depend on today may come into conflict with the code you are coordinating with when you least expect it. Is your code in a public version control repo?
