source helper scripts in test environment when running test_file

[jackwasey]

I have test harness data and functions in a helper-base.R file in tests/testthat/, andtest_file seems to rely on this being sourced manually, whereas test_package sets up a clean test environment.

Sourcing helper-base.R is a work-around, but pollutes the global environment, and I think it would be more consistent and simpler for test_file to source it for the user in a test environment.

Can you use devtools::test(filter = "...") or testthat::test_package(filter = "...")?

That's a good work-around, thanks for that. I think I'd still argue for test_file behaving in a similar way.

That sounds reasonable to me
