What does `rails spec` do that `rspec` does not?

Question

What is it that rails spec does, if anything, that rspec alone does not?

I was looking for a way to run only specific RSpec tests from the command line, and the only way I found requires running rspec directly (rspec --tag focus ..., not via rails spec. I could do that, but I'm concerned that maybe doing so bypassing some important setup or other functionality.

`rake` would work, but I believe starting with Rails 5, `rails` is the preferred way to invoke `spec`, `db:migrate`, etc. See https://stackoverflow.com/questions/38403533/rails-dbmigrate-vs-rake-dbmigrate. — Keith Bennett, Dec 17 '19 at 12:01

It seems it calls rails test:prepare before actually calling rspec:

Marek, thanks. Are you pretty sure that this the exact difference, that is, there are no other differences? – Keith Bennett Dec 21 '19 at 15:32
I am not, to be honest. But most of the times, testing with `rspec` works as expected. – Marek Lipka Dec 23 '19 at 06:05
