Jonny Harris e486ac0745 Query: Improved handling of filtered queries in WP_Query. 
The `WP_Query` class enables developers to customize queries using filters like `posts_fields_request`, `posts_request`, and `the_posts`, which can modify both the queried fields and retrieved post objects. In some cases with these filters, incomplete or invalid post objects lacking essential data may arise. To address this, if any of these filters are active during a query, the `get_posts` method now avoids caching post objects with the usual `update_post_caches` function call, opting for a call to `_prime_post_caches` instead. This may occasionally trigger new database queries to prime the post data cache. While this enhancement may result in rare additional database queries, it ensures that invalid post objects aren't cached, prioritizing data consistency and integrity in filtered query scenarios.

README.txt 

The short version:

1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
