Dennis Snell 4d562a102d HTML API: Ensure that breadcrumbs are properly retained after seeking.
In some cases, it's possible to seek back into a location found inside
an element which has been closed before the point in the document where
the `seek()` was made. In these cases the breadcrumb stack is lost, and
calling `get_breadcrumbs()` after the seek will return the wrong information.

In this patch, the HTML Processor takes a conservative approach and
moves to the front of the document, then reparses the document until
it reaches the sought-after location. This ensures consistency on
the stack of open elements and active formats, and preserves
breadcrumbs.

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.
