It seems obvious once you know, but at first I didn't realise that the
suite name is part of this format. Document it and add some examples.

v1->v2: Expanded to clarify that suite_glob and test_glob are two separate
	patterns. Also made some other trivial changes to formatting etc.

 ===============
 
 By passing a bash style glob filter to the ``exec`` or ``run``
-commands, we can run a subset of the tests built into a kernel . For
-example: if we only want to run KUnit resource tests, use:
+commands, we can run a subset of the tests built into a kernel,
+identified by a string like ``<suite_glob>[.<test_glob>]``.
+
+For example, to run the ``kunit-resource-test`` suite:
+
+.. code-block::
+
+	./tools/testing/kunit/kunit.py run kunit-resource-test
+
+To run a specific test from that suite:
+
+.. code-block::
+
+	./tools/testing/kunit/kunit.py run kunit-resource-test.kunit_resource_test
+
+To run all tests from suites whose names start with ``kunit``:
+
+.. code-block::
+
+	./tools/testing/kunit/kunit.py run 'kunit*'
+
+To run all tests whose name ends with ``remove_resource``:
+
+.. code-block::
+
+	./tools/testing/kunit/kunit.py run '*.*remove_resource'
+
+To run all tests whose name ends with ``remove_resource``, from suites whose
+names start with ``kunit``:
 
 .. code-block::
 
-	./tools/testing/kunit/kunit.py run 'kunit-resource*'
+	./tools/testing/kunit/kunit.py run 'kunit*.*remove_resource'
 
 This uses the standard glob format with wildcard characters.
