Testing 3rd party package in my local environment

General Usage
1

I am uncertain how to run the tests of the packages installed in my environment. When i write

] test package_name

It creates temporary project and manifest files.

Is it possible to run the test files in the environment where i ran ] test package_name? How do you ensure that all packages in the environment can function properly with the dependencie versions in the Manifest of my environment?

Does

using Pkg 
Pkg.test("package_name"; allow_reresolve = false)

work? Not sure if that tries to reuse the manifest in the current working directory of it is just doesn’t re-resolve the manifest in package_name.jl’s tests.
