]test in testenv?

[aplavin]

TestEnv makes it convenient during development and debugging to be in the test env and use test dependencies. But after playing around, one often wants to actually run the testsuite!
Currently, ]test in testenv doesn't work (of course) – it tries to test the temporary project. Can this command be redirected to testing the actual package? So that one doesn't have to switch manually

TestEnv.activate()
# do some code testing...

# now want to run the whole testsuite
]activate .  # would be nice if this wasn't needed
]test

I can't think of an easy way to do it.
I believe ] test PackageName where PackageName is the name of your package will work.

Possibly if we copy the UUID and name into the generated Project.toml it might work it out on its own, but I am not hopeful

Maybe we cannot redirect ]test, but could we provide an API function that does this? I thought that something like

import Pkg
function test_parent()
    p = Pkg.PREV_ENV_PATH
    if isempty(p)
        @warn "no previous environment, use TestEnv.activate()"
    else
        Pkg.test(p[])
    end
end

would work, but apparently TestEnv.jl activates packages without setting Pkg.PREV_ENV_PATH (on v1.11 which I tested), so this does not work. Nevertheless, if it saved the package at the time of calling TestEnv.activate(), this approach would work.

(Disclaimer: maybe it does save it, I am still working through the source so maybe I missed it.)
