Sergey Biryukov c438bebad1 Tests: Correct the WP_Test_Stream::mkdir() method.
The method attempted to check if there is already a file with the same name, however the conditional used an undefined variable.

This commit prevents directory creation if a file or directory with the same name already exists, bringing consistency with the PHP `mkdir()` implementation.

Includes adding missing documentation for the method.

Reference: [https://www.php.net/manual/en/streamwrapper.mkdir.php PHP Manual: streamWrapper::mkdir()].

Follow-up to [49230].

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.
