 Running Symfony Tests
 =====================
 
-Before submitting a :doc:`patch <patches>` for inclusion, you need to run the
-Symfony test suite to check that you have not broken anything.
+The Symfony project uses a third-party service which automatically runs tests
+for any submitted :doc:`patch <patches>`. If the new code breaks any test,
+the pull request will show an error message with a link to the full error details.

-To run the entire test suite, including tests that depend on external

-The test suite needs the following third-party libraries:
-
-* Doctrine
-* Swift Mailer
-* Twig
-* Monolog
-
-To install them all, use `Composer`_:

-Step 2: Install vendors.
+To run the Symfony test suite, `install PHPUnit`_ 4.2 (or later) first. Then,
