| Subject: | Undefined subroutine &Foo::Bar::f2 |
t/01-basic.t fails on some of my systems:
...
Undefined subroutine &Foo::Bar::f2 called at t/01-basic.t line 76.
# Tests were run but no plan was declared and done_testing() was not seen.
# Looks like your test exited with 255 just after 2.
t/01-basic.t .............
Dubious, test returned 255 (wstat 65280, 0xff00)
All 2 subtests passed
...
Just a guess: possibly the same problem as described in https://rt.cpan.org/Ticket/Display.html?id=131207 (a module named Foo::Bar already installed) and a possible solution could be something similar as described in https://rt.cpan.org/Ticket/Display.html?id=131249 (use a namespace for the test packages you own).
