The [test:unit|INFO] task launches unit tests:

  [./symfony test:unit|INFO]

The task launches all tests found in [test/unit|COMMENT].

If some tests fail, you can use the [--trace|COMMENT] option to have more
information about the failures:

  [./symfony test:unit -t|INFO]

You can launch unit tests for a specific name:

  [./symfony test:unit strtolower|INFO]

You can also launch unit tests for several names:

  [./symfony test:unit strtolower strtoupper|INFO]

The task can output a JUnit compatible XML log file with the [--xml|COMMENT]
options:

  [./symfony test:unit --xml=log.xml|INFO]
