+Q: Can I find out which tests ran which lines?
+..............................................
+
+Yes! Coverage.py has a feature called :ref:`dynamic_contexts` which can collect
+this information.  Add this to your .coveragerc file::
+
+    [run]
+    dynamic_context = test_function

+Coverage.py can do a number of things:
+
+- By default it will measure line (statement) coverage.
+
+- It can also measure :ref:`branch coverage <branch>`.
+
+- It can tell you :ref:`what tests ran which lines <dynamic_contexts>`.
+
+- It can produce reports in a number of formats: :ref:`text <cmd_report>`,
+  :ref:`HTML <cmd_html>`, :ref:`XML <cmd_xml>`, and :ref:`JSON <cmd_json>`.
+
+- For advanced uses, there's an :ref:`API <api>`, and the result data is
+  available in a :ref:`SQLite database <dbschema>`.
