Boone Gorges 1708a580fd Overhaul SQL generating logic in WP_Meta_Query to avoid unnecessary table joins. The logic used to generate clause SQL in `WP_Meta_Query` is somewhat arcane, stemming mostly from an ongoing effort to eliminate costly table joins when they are not necessary. By systematizing the process of looking for shareable joins - as was done in `WP_Tax_Query` [29902] - it becomes possible to simplify the construction of SQL queries in `get_sql_for_clause()`. Moreover, the simplified logic is actually considerably better at identifying shareable joins, such that certain uses of `WP_Meta_Query` will see joins reduced by 50% or more. Includes integration tests for a representative cross-section of the query clause combinations that result in shared table aliases. Props boonebgorges, sc0ttkclark. See #24093. git-svn-id: https://develop.svn.wordpress.org/trunk@29940 602fd350-edb4-49c9-b593-d223f7449a82		2014-10-17 20:20:04 +00:00

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.
