Colin Stewart 7d96189ba1 Build/Test Tools: Add sys_get_temp_dir() to open_basedir tests.
In PHPUnit 10.3.5, 9.6.13 and 8.5.34, the child processes used for process isolation now use temporary files to communicate their result to the parent process.

This caused a failure in some tests that set the `open_basedir` PHP directive to a value that did not include `sys_get_temp_dir()`.

This adds `sys_get_temp_dir()` to the `open_basedir` value set by the tests to ensure that permission is still granted for the temporary directory.

PHPUnit uses `sys_get_temp_dir()`. To ensure the result is the same, Core's `get_temp_dir()` function is not used.

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.
