Many projects have a Project.toml that lists test dependencies in the `[extras]` block, following by a

```julia
[targets]
test = [...]

```

block. This way, you can run `julia --project` in the base project directory and then `]test` will automatically pull in all those dependencies.

However, for development purposes, I want to install the extra packages into the base project directory, without actually modifying `Project.toml` to change them into hard dependencies. Is there a way to do `]instantiate` that also includes the extras? E.g. `]instantiate extras`?

I think what you’re looking for is [GitHub - JuliaTesting/TestEnv.jl: Activate your test enviroment, so you can use your test dependencies in the REPL](https://github.com/JuliaTesting/TestEnv.jl)

But then I need to add TestEnv to the dependencies… or do you just install this to your global Julia env?

Install it in the global env, and use it with each of your packages
