Alexander, I’ve tried your suggestion on brew update and created the issue on testing suites list, check the following.

After installing brew you'll have fresh brew, but no formulae, I guess.
Will the next `brew install` work? I guess, no. You need `brew update`
after this.
I’ve tried to remove the brew and reinstalled it with this command, seems that all needed updates were tried to do during the installation:
==> Tapping homebrew/core
Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...
remote: Enumerating objects: 699135, done.
remote: Total 699135 (delta 0), reused 0 (delta 0), pack-reused 699135
Receiving objects: 100% (699135/699135), 283.20 MiB | 8.49 MiB/s, done.
Resolving deltas: 100% (459609/459609), done.
Tapped 2 commands and 4942 formulae (5,205 files, 310.5MB).
Already up-to-date.

Also the next command with installation passed without any issues and installed all the needed packages.

So it seems logical to do `[ -z "$(which brew) "] && ruby
brew_install_script; brew update` rather than `brew update || ruby
brew_install_script`.

Developers doing `make test` or `cd test && ./test-run.py`. Nobody want
to run a testing script and found that something was changed in its
system. So I'm still on my view.

'It' -- the option? Okay so. Good piece of information to add to the
commit message.
Ok, added.

Okay. Yep, it seems pip assumes --user by default in Travis CI. Maybe I
wrongly remember that --user was added for Travis CI (AFAIR it was done
by Arseniy).

Let's add the info about Mac OS X testing into the relevant issue to
track disabled tests (AFAIR you have one, but it was about testing
during RPM packages build).
Ok, sure:

Why it was okay, but becomes too long?
Because the name of the user on the new mac mini and its home path is really long
echo ~ | wc -c
      28
also the path of tarantool/test/var adds.
