Globals like `$pages` were leaking between tests, resulting in various
bits of weirdness.

Filters and actions have been the basis of WordPress' plugin functionality since time immemorial, they've always been a reliable method for acting upon the current state of WordPress, and will continue to be so.
Over the years, however, edge cases have cropped up. Particularly when it comes to recursively executing hooks, or a hook adding and removing itself, the existing implementation struggled to keep up with more complex use cases.
And so, we introduce `WP_Hook`. By changing `$wp_filter` from an array of arrays, to an array of objects, we reduce the complexity of the hook handling code, as the processing code (see `::apply_filters()`) only needs to be aware of itself, rather than the state of all hooks. At the same time, we're able te handle more complex use cases, as the object can more easily keep track of its own state than an array ever could.

* Automatically delete objects that we were created during `wpSetUpBeforeClass` - posts, comments, terms (except 1), and user (except 1)
* The amount of leftover data between tests was breathtaking - use the new function: `_delete_all_data()`
* Commit database transactions for all `TestCase`s, not just those that implement `wpSetUpBeforeClass` and `wpTearDownAfterClass`
* The tests run 10-20 seconds faster now

When a filter or action hook is deprecated, the corresponding `apply_filters()`
or `do_action()` calls should be switched out with `apply_filters_deprecated()`
or `do_action_deprecated()`. The latter functions will throw a deprecation
before invoking the original hook.

Using more than one instance of `WP_UnitTest_Factory` causes all kinds of craziness, due to out-of-sync internal generator sequences. Since we want to use `setUpBeforeClass`, we were creating ad hoc instances. To avoid that, we were injecting one `static` instance via Dependency Injection in `wpSetUpBeforeClass`. All tests should really use the `static` instance, so we will remove the instance prop `$factory`.
Replace `$this->factory` with `self::$factory` over 2000 times.
Rewrite all of the tests that were hard-coding dynamic values.

This makes it way easier to add fixtures, and tear them down, without needing to instantiate `WP_UnitTest_Factory` in every class - removes the need to call `commit_transaction()` in each individual class.

The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.
A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available. However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.
The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.

Renames `reset_permalinks()` to `set_permalink_structure()` (mimicking `$wp_rewrite->set_permalink_structure()`) and allows it to accept an optional permalink structure. In this way, we can double dip using it to both set and reset the permalink structure from anywhere.
Removes alot of duplicated code from tests.

Continuing with the "code is poetry" theme after [34719], we need to continue
to update the option in the database on non-multisite in this
`wp_insert_term()` test.

[34718] introduced a 'db_version' check to term meta functions, to ensure that
they don't run when the term meta schema is not yet in place. This call to
`get_option()` causes a database hit during Multisite tests, due to the
presence of the `WP_INSTALLING` constant. See #31130. The extra database
queries are causing cache tests to fail.
In similar cases, we have `markTestSkipped()` when `is_multisite()`. Because
the term meta API is so extensive - term meta caches can be primed anywhere a
`WP_Query` loop is fired up - we implement a more generous workaround in this
case. To prevent `get_option( 'db_version' )` from hitting the database during
multisite unit tests, we use a 'pre_option_' filter.
Heaven help us.

Failure to set this variable meant that passing the home URL to `go_to()`
(without a trailing slash) resulted in a PHP notice, and failed to reset the
globals properly.

* Do the `expectedDeprecated()` check in `assertPostConditions()` instead of `tearDown()`. Previously, `fail`ing inside of `tearDown()` was causing the rest of the teardown process to be aborted, resulting in inter-test leakage.
* Collect all `expectedDeprecated` and `expectedIncorrectUsage` annotations in an entire method and display them all when `fail`ing, instead of showing only the first one.

Examples: if you clean up directories in a test, or a test fails before the directories are cleaned, or a test fails before the `'upload_path'` option is reset, the next call to `wp_upload_dir()` will recreate the directories you just tried to delete.
These changes ensure that `src/foo` and `/tmp/wp-unit-test` directories are deleted immediately after `wp_upload_dir()` is fired in the tests.

In general, skipped tests should live only in patches, which are committed at
the same time that the corresponding bug is fixed. In cases where it's
necessary to skip a test, use `markTestSkipped()` to declare this fact
explicitly.
We continue to check Trac when using `WP_UnitTestCase` to run non-core tests.

microtime is by default a string. Doing a greater then or less than check of that string is a bad idea since it uses the first part (the micro part of microtime) rather then the actual time. This adds a helper to convert microtime output into a float which we can then use to properly compare the output of microtime.
This fixes an intermittent test failure.

A growing number of plugins and other WP-based projects use the core test
tools, such as WP_UnitTestCase, as the basis of their own tests and continuous
integration setups. At the same time, many of these third-party plugins use
custom post types and taxonomies, which are generally registered a single time
during a run of the tests: at 'init', before the testcases have run. Wiping out
these globals between tests will mess with these third-party builds.
Best practice for plugin developers is probably to clean up their own post types
and taxonomies and then reinitialize before each test. But, in the interest of
not breaking everyone's builds, the core test suite will not enforce this.
Fixes#29827.
git-svn-id: https://develop.svn.wordpress.org/trunk@29869 602fd350-edb4-49c9-b593-d223f7449a82
Registering a post type or taxonomy during a unit test causes modifications to
global variables. If the test fails to clean up these globals - either by
neglecting to call _unregister_post_type()/_unregister_taxonomy() at all or by
failing before getting a chance to do so - tests that run later in the suite
can fail, leading to much gnashing of teeth. Wiping all taxonomies and
restoring to the defaults before each test ensures that we always start with a
clean slate.
