needed to test the Symfony core code itself.

Each test - whether it's a unit test or a functional test - is a PHP class

that should live in the `Tests/` subdirectory of your bundles. If you follow

that should live in the ``Tests/`` subdirectory of your bundles. If you follow

this rule, then you can run all of your application's tests with the following

command:

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 tweak the configuration for your local machine.

``app/phpunit.xml.dist`` file. You can edit this file to change the defaults or

create an ``app/phpunit.xml`` file to setup a configuration for your local

machine only.

Store the ``phpunit.xml.dist`` file in your code repository and ignore the

By default, only the tests stored in "standard" bundles are run by the

``phpunit`` command (standard being tests in the ``src/*/Bundle/Tests`` or

``src/*/Bundle/*Bundle/Tests`` directories) But you can easily add more

directories. For instance, the following configuration adds the tests from

the installed third-party bundles:

By default, only the tests from your own custom bundles stored in the standard

directories ``src/*/*Bundle/Tests`` or ``src/*/Bundle/*Bundle/Tests`` are run

by the ``phpunit`` command, as configured in the ``phpunit.xml.dist`` file:

..code-block::xml

But you can easily add more directories. For instance, the following

configuration adds tests from a custom ``lib/tests`` directory:

..code-block::xml

To include other directories in the code coverage, also edit the ``<filter>``

section:

..code-block::xml
