Regexp#match? should be considered to be part of the Ruby core library. We are
emulating it for < 2.4, but not having to require the extension is part of the
illusion of the emulation.

`#get`, `#set`, `[]=`, `add_on_empty` and `add_on_blank`.

Should be ActiveRecord::Attributes (ActiveModel::Attributes does not exist)

assert [1, 3].includes?(2) fails with unhelpful "Asserting failed" message

assert_includes [1, 3], 2 fails with "Expected [1, 3] to include 2" which makes it easier to debug and more obvious what went wrong

Fix potentially misleading example.

All indentation was normalized by rubocop auto-correct at 80e66cc4.
But comments was still kept absolute position. This commit aligns
comments with method definitions for consistency.

Recently, the Rails team made an effort to keep the source code consistent, using Ruboco
(bb1ecdcc and below). Some of the case
statements were missed.

This changes the case statements' formatting and is consistent with changes
in 810dff7c and db63406c.

NumericalityValidator#validate_each is never called when allow_nil is true and
the value is nil because it is already skipped in EachValidator#validate.

Thinking .. relative to files is not natural, we are used
to think "parent of a directory", and we have __dir__
nowadays.

Hash syntax auto-correcting breaks alignments. 411ccbda

A few have been left for aesthetic reasons, but have made a pass
and removed most of them.

Note that if the method `foo` returns an array, `foo << 1`
is a regular push, nothing to do with assignments, so
no self required.

Some case expressions remain, need to think about those ones.

The current code base is not uniform. After some discussion,
we have chosen to go with double quotes by default.

In Ruby ^ and $ mean start and end of *line*.

A regexp that validates an email should not check if
some line of the string looks like an email, and maybe
be surrounded by the entire Joyce's Ulysses. What the
regexp has to check is if the string itself looks like
an email.

This validator is used only in tests, the ^/$ anchors
implied no risk.

add documentation of the behaviors of type coercion at the class level

Fix a tiny typo and vertical-align some return results in the
ActiveModel::Errors documentation.

Fixes #25410.
