How to install packages which are needed only for development

On my system, I installed all those packages in the default (v1.1) environment. Is that the correct way of doing things?

It’s one way, I usually use that myself

@ffevotte

It appears to me that, when a package is activated, you get access to:

Yea, well, if those are in the LOAD_PATH (see below).

@ffevotte

is it possible to avoid by-hand editing of Project.toml ?

No.

@ffevotte

nother thing which is not clear to me: in which environment does Pkg.test install test-specific dependencies if they were missing?

It’s a temporary environment that is cleaned up when tests are done.

@ffevotte

I haven’t found any place in the documentation (neither of modules nor of Pkg) where these details are clearly documented.

Stacking of LOAD_PATH is documenter here: Environment Variables · The Julia Language.

Question 1: Is the above a good way of doing things ?

Sure, seems easiest.

Question 2: How can I test this? I.e make sure I did not forget any tools in my list. I currently:

1. move the whole ~/.julia directory away;
2. try and install everything in an empty environment, then check that I can perform everything asked in the training session;
3. move my original ~/.julia back.

Is there a better way of doing this?

Instead of moving things you can set DEPOT_PATH to some test-directory, e.g. by setting JULIA_DEPOT_PATH, see Environment Variables · The Julia Language
