 Available Tests
 ===============
 
 Tests can be listed with ``ansible-test sanity --list-tests``.
 
-This list is a combination of two different categories of tests, "Code Smell" and "Built-in".
+See the full list of :ref:`sanity tests <all_sanity_tests>`, which details the various tests and details how to fix identified issues.
-
-Code Smell Tests
-----------------
-
-Miscellaneous `scripts <https://github.com/ansible/ansible/tree/devel/test/sanity/code-smell/>`_ used for enforcing coding standards and requirements, identifying trip hazards, etc.
-
-These tests are listed and accessed by script name. There is no actual test named ``code-smell``.
-
-All executable scripts added to the ``code-smell`` directory are automatically detected and executed by ``ansible-test``.
-
-Scripts in the directory which fail can be skipped by adding them to `skip.txt <https://github.com/ansible/ansible/blob/devel/test/sanity/code-smell/skip.txt>`_.
-This is useful for scripts which identify issues that have not yet been resolved in the code base.
-
-Files tested are specific to the individual test scripts and are not affected by command line arguments.
-
-Built-in Tests
---------------
-
-These tests are integrated directly into ``ansible-test``.
-All files relevant to each test are tested unless specific files are specified.
-
-A full list of tests can be obtained by doing ``ansible-test sanity --list-tests``.
-

-~~~~~~~~~~~
-
-Verifies that ``ansible-doc`` can parse module documentation on all supported python versions.
