+How to test code that interacts with the Database
+=================================================
 
-If your code interacts with the database, e.g. reads data from or stores data into
-it, you need to adjust your tests to take this into account. There are many ways
-how to deal with this. In a unit test, you can create a mock for a ``Repository``
-and use it to return expected objects. In a functional test, you may need to
-prepare a test database with predefined values, so a test always has the same data
-to work with.

 Mocking the ``Repository`` in a Unit Test

+If you want to test code which depends on a doctrine ``Repository`` in isolation,
+you need to mock the ``Repository``. Normally you inject the ``EntityManager``
+into your class and use it to get the repository. This makes things a little
+more difficult as you need to mock both the ``EntityManager`` and your repository
+class.
+
+.. tip::
+
+    It is possible (and a good idea) to inject your repository directly by
+    registering your repository as a :doc:`factory service</components/dependency_injection/factories>`
+    This is a little bit more work to setup, but makes testing easier as you
+    only need to mock the repository.
