It seems like `Pkg.test` is slow because I am using some bigger packages in my own like `JuMP` and `Ipopt`.  
Is it possible to include them before so these unchanged packages don’t get compiled every time I run my tests?  
I tried to use `using JuMP, Ipopt` before running `Pkg.test()` but then the modules are unknown.  
That probably makes sense because `Pkg.test` should run in its own container.  
Whatever… is there any way?

`include("your_package/test/runtest.jl")`? That’ll run the tests in the current session.

But that doesn’t recompile my package, right? I think this will use the old version if I change something.

It will recompile the package if you run it in a new Julia session.

Yes but then I have no advantage because everything will be compiled then, right?

Right, so either `reload` your package, or use [Revise.jl](https://github.com/timholy/Revise.jl)

+1 to Revise.jl

Only packages that changed will be recompiled. Also, one thing that can contribute to slow `Pkg.test` is if you have a `test/REQUIRE` file as then it will always resolve package dependency on testing.
