The problem with the current approach is that the "expect()" calls
happen inside "tests/Pest.php". That means that when something fails, we
can't easily know which exact expectation has failed.
This commit will change the helper functions, and will make the tests
more verbose, but event with that, the developer experience is better.
When nested-structural validation fails, it's challenging to identify
which rule failed from the main exception message. A great example is
the `Issue796Test.php` file. The exception message says:
host must be a string
But you're left unsure whether it's the `host` key from the `mysql` key
or the `postgresql` key.
This commit changes that behaviour by introducing the concept of "Path."
The `path` represents the path that a rule has taken, and we can use it
in structural rules to identify the path of an array or object.
Here's what it looks like before and after:
```diff
-host must be a string
+`.mysql.host` must be a string
```
Because paths are a specific concept, I added a dot (`.`) at the
beginning of all paths when displaying them. I was inspired by the `jq`
syntax. I also added backticks around paths to distinguish them from any
other value.
I didn't manage to fix a test, and I skipped it instead of fixing it
because I want to make changes in how we display error messages as
arrays, and it will be easier to fix it then.
Some templates were a bit confusing, and I would like to favour adding
the `{{name}}` at the beginning of the templates as it helps when
reading nested messages.
I also deleted the regression tests for issue #1348, because it's a
non-issue, actually. The best approach to that problem is indeed using
`When` insteaf of `OneOf`.
Because of how the validation engine works now [1], there's no reason to
keep adding names to each rule. Instead, create a single rule that
handles naming rules with a few other accessories. This change is not
necessarily simple, but it shrinks the `Rule` interface, and it's more
aligned with how the library works right now.
Personally, I think this API is much more straightforward than the
`setName()` method, as it's way more explicit about which rule we're
naming. Because of this change, the behaviour changed slightly, but it's
for the best.
Because of this change, I managed to remove a lot of code, but
unfortunately, it's quite a big-bang commit. It would be too complicated
to make it atomic since names are an intrinsic part of the library.

The "NotBlank", "NotEmpty", and "NotUndef" rules do not display the
input in all cases and instead displays the string "The value". The
problem with that is that one doesn't see which value was passed, which
is not so useful.
This commit will changes those rules to always display the input. If
someone doesn't want the input to show, they can always set a name for
the rule.
Although I love PHPT files, and I've done my fair share of making it
easier to write them in this library, they're very slow, and running
them has become a hindrance.
I've been fidgeting with the idea of using Pest for a while, and I think
it's the right tool for the job. I had to create a couple of functions
to make it easier to run those tests, and now they're working really
alright.
I migrated all the PHPT files into Pest files -- I automated most of the
work with a little script using "nikic/php-parser"; this commit should
contain all the previous PHPT tests as Pest tests.
The previous integration tests would take sixteen seconds, and the Pest
tests take less than a second.
