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

```julia
] 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

```julia
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.
