+Tests
+=============
+
+Unit tests
+--------------
+
+There is a comprehensive test suite employing CMocka_. You can run all of them using ``ctest`` in the build directory. Individual tests are themselves runnable. Please refer to `CTest <http://www.cmake.org/Wiki/CMake/Testing_With_CTest>`_ documentation for detailed information on how to specify particular subset of tests.
+
+.. _CMocka: http://cmocka.org/
+
+Testing for memory leaks
+------------------------
+
+Every release is tested for memory correctness. You can run these tests by passing the ``-T memcheck`` flag to ``ctest``. [#]_
+
+.. [#] Project should be configured with ``-DCMAKE_BUILD_TYPE=Debug`` to obtain meaningful description of location of the leak. You might also need ``--dsymutil=yes`` on OS X.
+
+
+Code coverage
+-------------------
+
+Every release is inspected using `GCOV/LCOV <http://ltp.sourceforge.net/coverage/lcov.php>`_. Platform-independent code should be fully covered by the test suite. Simply run
+
+.. code-block:: bash
+
+  make coverage
+
+
+or alternatively run ``lcov`` by hand using
+
+.. code-block:: bash
+
+  lcov --capture --directory . --output-file coverage.info
+  genhtml coverage.info --output-directory out
+
+Fuzz testing
+-----------------
+
+Every release is tested using a fuzz test. In this test, a huge buffer filled with random data is passed to the decoder. We require that it either succeeds or fail with a sensible error, without leaking any memory. This is intended to simulate real-world situations where data received from the network are CBOR-decoded before any further processing.
