Feature request: copy-pasteable test filters

[gibfahn]

Motivation

Today I have to remember how to pass three different kinds of filters to cargo test or cargo nextest run. I end up having to look these up every time.

Nextest has made a lot of things easier, one of which being that it's really easy to see what each test is called, and where it is in the hierarchy, as they all get listed out as they run.

A common debugging flow for me is:

• cargo nextest run --run-ignored=all
• A test fails
• I want to just run that test
• I copy the failing test line and try to paste it into nexttest's filter
• It doesn't work, so I go look at the help to work out what to do

Proposal

If I have a line in cargo nextest run like:

FAIL [   0.009s] clap_config::clap_skipped main

I want to be able to do something like:

cargo nextest run clap_config::clap_skipped main

to run that test. Instead today I have to do (I think this is right):

cargo nextest run -p clap_config --test clap_skipped -- main

Alternatives

I don't understand enough about how things work today and what would be a breaking change to know the best way to do this. Maybe the easiest way would be to change the format that the tests are printed in today? e.g. maybe something like:

-PASS [   0.022s] mycrate utils::version_sort::tests::test_nonlexical_float
+PASS [   0.022s] ::mycrate::utils::version_sort::tests::test_nonlexical_float

and then cargo nextest run understands that a leading :: means to use this filtering method or something.
