cli: `pio run --list-targets` should show `envdump`, `exec`, `test` [and others?]

[MacDada]

Configuration

Operating system: MacOS 12.6.1

PlatformIO Version (platformio --version): 6.1.5

Description of problem

When I type pio run --list-targets I don't see the test target. I guess it should be listed, as it actually exists [?].

Actual Results

✗ pio run --list-targets
Environment    Group     Name         Title                        Description

Expected Results

Same as above, but also test target listed.

Additional info

I don't know how I know about the test target. Maybe I just experimented, maybe I read about it somewhere in the docs. Anyway, pio run --target test does work, so it is a target, so my intuition is that it should be listed.

# dump current build environment
pio run --target envdump

OK, so it is not only test, but also envdump and maybe some other values that I don't know about yet. I wish I could get to know them by running --list-targets ;-)

And another one…

To execute a native program, you need to use exec target for the pio run --target command.

~ https://docs.platformio.org/en/latest/platforms/native.html#running-of-program

The exec target is not listed:

✗ pio run -e native --list-targets
Environment    Group    Name    Title    Description
-------------  -------  ------  -------  -------------

But it works:

✗ pio run -e native --target exec
