I wanted to poke around Distributed.jl. But the tests on the current commit included in Julia 1.10 are failing. I tried to clone Distributed.jl, activate its project, and then `import` it (per the instructions in the Pkg.jl readme), but since the tests start separate processes, the test processes don’t have the import fix.

So I need to build Julia from source. Not a huge deal, but on my 11th gen i5 laptop, it takes 10ish minutes to build Julia which is pretty rough to have in your testing hot loop.

Is there a better way?

You can download the nightly and then you should be able to dev it

To clarify:

1. [Download nightly binary here](https://julialang.org/downloads/nightlies/)
2. Clone Distributed.jl master branch into my `dev` directory for that nightly install
3. Using nightly REPL, run

```julia
] 
pkg> generate testing_distributed
pkg> activate testing_distributed
pkg> develop Distributed

```

But then how do I run the tests for Distributed.jl?
