Test.jl and `@testset` are saving my package, but why? (and how make it work without them)

Hi there!

Test.jl and @testset are saving my package in a funny way (and I don’t understand why yet). I am making a semi-automated performance checking package PerfChecker.jl

I use a method in the package with one of its argument being a function called pre_alloc (see the error below). Probably due to environment issues on a distributed worker, the error below is raised.
The code is in /perf/allocs.jl and it uses an env local to /perf/

The funny part is that it works perfectly fine within a test environment (such as the one in test/runtests.jl).

Any idea of what is happening, and how can I make it work outside the (magical) test env?

Issue Allocations check works only within a test environment · Issue #2 · JuliaConstraints/PerfChecker.jl (github.com) is open to discuss it.
