Include ActiveSupport::Testing::TaggedLogging for Rails >= 7 (rebased)

[JonRowe]

This is #2580 rebased

The failure is due to this line calling name. I recall we have had and had fixed a similar problem not long ago.

Green.
I have mixed feeling from defining the name method for all Rails example groups. A spec with let(:name) works as expected.
Wondering what other side effects might be.

A let(:name) { .. } would override the definition here, and thus if it was not string safe it likely would break... but... this is the case regardless...

I see what you mean. With the var naming, though, name, chances of it not having a to_s are lower.
Still, it would be a weird side effect to show it in tagged logging output.
As far as I understand it, name should evaluate to the example title.
Any idea why it is not yet available in this context?
I tried with RSpec.current_example.metadata[:name], it was empty too.
In any case, @example resolves to nil. And it's not because it's explicitly nullified in the constructor, it is nil if you set a breakpoint above, too.

As an alternative approach with no side effects, we would have to wrap tagger_logger, delegate to it, and provide it some name. In the best case, our example name. Or just nil if it turns out to be impossible.
I can take a stab at it if you think it's a viable approach.

Unfortunately enough, name is used not only in before_setup, but in assertions, too, e.g. this:

        def _assert_nothing_raised_or_warn(assertion, &block)
          assert_nothing_raised(&block)
        rescue Minitest::UnexpectedError => e
          if tagged_logger && tagged_logger.warn?  warning = <<~MSG
              #{self.class} - #{name}: #{e.error.class} raised.

I'll push the wrapped that I've written, but it fails.

I'd go with a risk of name raising when its definition is incapable of .to_s, and it logging nonsense when name is defined.
@JonRowe Any objections on merging as is?
