+Selecing tests based on their node ID
+-------------------------------------
+
+You can provide one or more node IDs as positional arguments to select
+only specified tests. This makes it easy to select tests based on
+their module, class, method, or function name::
+
+    $ py.test -v test_server.py::TestClass::test_method
+    =========================== test session starts ============================
+    platform linux2 -- Python 2.7.3 -- py-1.4.20 -- pytest-2.5.2 -- /home/hpk/p/pytest/.tox/regen/bin/python

+
+    test_server.py:11: TestClass.test_method PASSED
+
+    ========================= 1 passed in 0.01 seconds =========================
+
+You can also select on the class::
+
+    $ py.test -v test_server.py::TestClass
+    =========================== test session starts ============================
+    platform linux2 -- Python 2.7.3 -- py-1.4.20 -- pytest-2.5.2 -- /home/hpk/p/pytest/.tox/regen/bin/python
+    collecting ... collected 4 items
+
+    test_server.py:11: TestClass.test_method PASSED
+
+    ========================= 1 passed in 0.01 seconds =========================
+
+Or select multiple nodes::
+
+  $ py.test -v test_server.py::TestClass test_server.py::test_send_http
+    =========================== test session starts ============================
+    platform linux2 -- Python 2.7.3 -- py-1.4.20 -- pytest-2.5.2 -- /home/hpk/p/pytest/.tox/regen/bin/python

+    test_server.py:3: test_send_http PASSED
+
+    ========================= 2 passed in 0.01 seconds =========================
+
+.. note::
+
+    Node IDs are of the form ``module.py::class::method`` or
+    ``module.py::function``.  Node IDs control which tests are
+    collected, so ``module.py::class`` will select all test methods
+    on the class.  Nodes are also created for each parameter of a
+    parametrized fixture or test, so selecting a parametrized test
+    must include the parameter value, e.g.
+    ``module.py::function[param]``.
+
+    Node IDs for failing tests are displayed in the test summary info
+    when running py.test with the ``-rf`` option.  You can also
+    construct Node IDs from the output of ``py.test --collectonly``.
