-Time-sensitive Tests
---------------------
-
-Use Case
-~~~~~~~~
-
-If you have this kind of time-related tests::
-
-    use Symfony\Component\Stopwatch\Stopwatch;
-
-    class MyTest extends \PHPUnit_Framework_TestCase
-    {
-        public function testSomething()
-        {
-            $stopwatch = new Stopwatch();
-
-            $stopwatch->start();
-            sleep(10);
-            $duration = $stopwatch->stop();
-
-            $this->assertEquals(10, $duration);
-        }
-    }
-
-You used the :doc:`Symfony Stopwatch Component </components/stopwatch>` to
-calculate the duration time of your process, here 10 seconds. However, depending
-on the load of the server your the processes running on your local machine, the
-``$duration`` could for example be `10.000023s` instead of `10s`.
-
-This kind of tests are called transient tests: they are failing randomly
-depending on spurious and external circumstances. They are often cause trouble
-when using public continuous integration services like `Travis CI`_.
-
-Clock Mocking
-~~~~~~~~~~~~~
-
-The :class:`Symfony\\Bridge\\PhpUnit\\ClockMock` class provided by this bridge
-allows you to mock the PHP's built-in time functions ``time()``,
-``microtime()``, ``sleep()`` and ``usleep()``.
-
-To use the ``ClockMock`` class in your test, you can:
-
-* (**Recommended**) Add the ``@group time-sensitive`` annotation to its class or
-  method;
-
-* Register it manually by calling ``ClockMock::register(__CLASS__)`` and
-  ``ClockMock::withClockMock(true)`` before the test and
-  ``ClockMock::withClockMock(false)`` after the test.
-
-As a result, the following is guarenteed to work and is no longer a transient
-test::
-
-    use Symfony\Component\Stopwatch\Stopwatch;
-
-    /**
-     * @group time-sensitive
-     */
-    class MyTest extends \PHPUnit_Framework_TestCase
-    {
-        public function testSomething()
-        {
-            $stopwatch = new Stopwatch();
-
-            $stopwatch->start();
-            sleep(10);
-            $duration = $stopwatch->stop();
-
-            $this->assertEquals(10, $duration);
-        }
-    }
-
-And that's all!
-
-.. tip::
-
-    An added bonus of using the ``ClockMock`` class is that time passes
-    instantly. Using PHP's ``sleep(10)`` will make your test wait for 10
-    actual seconds (more or less). In contrast, the ``ClockMock`` class
-    advances the internal clock the given number of seconds without actually
-    waiting that time, so your test will execute 10 seconds faster.
-
-Troubleshooting
-~~~~~~~~~~~~~~~
-
-The ``@group time-sensitive`` works "by convention" and assumes that the
-namespace of the tested class can be obtained just by removing the ``\Tests\``
-part from the test namespace. I.e. that if the your test case fully-qualified
-class name (FQCN) is ``App\Tests\Watch\DummyWatchTest``, it assumes the tested
-class FQCN is ``App\Watch\DummyWatch``.
-
-If this convention doesn't work for your application, you can also configure
-the mocked namespaces in the ``phpunit.xml`` file, as done for example in the
-:doc:`HttpKernel Component </components/http_kernel/introduction>`:
-
-.. code-block:: xml
-
-    <!-- http://phpunit.de/manual/4.1/en/appendixes.configuration.html -->
-    <phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
-             xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/4.1/phpunit.xsd"
