John Blackbourn 4ab922d224 Build/Test Tools: Switch back to running the PHPUnit test suite against the src directory instead of build.
Some PHPUnit tests were concerned with the state of files in the `build` directory. In order to allow the tests to run without requiring a build to be run first, these have been moved into assertions that run after the build step (and therefore cause it to fail if they do not pass), or into QUnit tests as necessary.

Various other PHPUnit tests implictly depend on built JavaScript files being present. These files are now touched during the test setup to avoid PHP warnings if the `build` files are not present.

The `wp-tests-config-sample.php` file and the GitHub Actions configuration have also been changed so `ABSPATH` uses `src` instead of `build`, therefore allowing the PHPUnit tests to be run without a build having to be run first. This means all new local installations of WordPress will use `src` for PHPUnit testing. If you would like to switch your existing installation over then change the location of `ABSPATH` in `wp-tests-config.php` to point to `src` instead of `build`.

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.
