-PHPUnit Configuration
----------------------
-
-Each application has its own PHPUnit configuration, stored in the
-``phpunit.xml.dist`` file. You can edit this file to change the defaults or
-create a ``phpunit.xml`` file to set up a configuration for your local machine
-only.
-
-.. tip::
-
-    Store the ``phpunit.xml.dist`` file in your code repository and ignore
-    the ``phpunit.xml`` file.
-
-By default, only the tests stored in ``tests/`` are run via the ``phpunit`` command,
-as configured in the ``phpunit.xml.dist`` file:
-
-.. code-block:: xml
-
-    <!-- phpunit.xml.dist -->
-    <phpunit>
-        <!-- ... -->
-        <testsuites>
-            <testsuite name="Project Test Suite">
-                <directory>tests</directory>
-            </testsuite>
-        </testsuites>
-        <!-- ... -->
-    </phpunit>
-
-But you can add more directories. For instance, the following
-configuration adds tests from a custom ``lib/tests`` directory:
-
-.. code-block:: xml
-
-    <!-- phpunit.xml.dist -->
-    <phpunit>
-        <!-- ... -->
-        <testsuites>
-            <testsuite name="Project Test Suite">
-                <!-- ... -->
-                <directory>lib/tests</directory>
-            </testsuite>
-        </testsuites>
-        <!-- ... -->
-    </phpunit>
-
-To include other directories in the `code coverage analysis`_, also edit the
-``<filter>`` section:
-
-.. code-block:: xml
-
-    <!-- phpunit.xml.dist -->
-    <phpunit>
-        <!-- ... -->
-        <filter>
-            <whitelist>
-                <!-- ... -->
-                <directory>lib</directory>
-                <exclude>
-                    <!-- ... -->
-                    <directory>lib/tests</directory>
-                </exclude>
-            </whitelist>
-        </filter>
-        <!-- ... -->
-    </phpunit>
