+This guide is a starting point for configuring Tempest. It aims to elaborate
 on and explain some of the mandatory and common configuration settings and how
 they are used in conjunction. The source of truth on each option is the sample
 config file which explains the purpose of each individual option. You can see
 the sample config file here: :ref:`tempest-sampleconf`
 
-Lock Path
----------
-
-There are some tests and operations inside of tempest that need to be
-externally locked when running in parallel to prevent them from running at
-the same time. This is a mandatory step for configuring tempest and is still
-needed even when running serially. All that is needed to do this is:
-
- #. Set the lock_path option in the oslo_concurrency group

 Auth/Credentials

-Tempest currently has 2 different ways in configuration to provide credentials
-to use when running tempest. One is a traditional set of configuration options
-in the tempest.conf file. These options are in the identity section and let you
-specify a regular user, a global admin user, and an alternate user set of
-credentials. (which consist of a username, password, and project/tenant name)

-Tempest Field Guide to Third Party API tests
-============================================
-
-
-What are these tests?
----------------------
-
-Third party tests are tests for non native OpenStack APIs that are
-part of OpenStack projects. If we ship an API, we're really required
-to ensure that it's working.
-
-An example is that Nova Compute currently has EC2 API support in tree,
-which should be tested as part of normal process.
-
-
-Why are these tests in tempest?
--------------------------------
-
-If we ship an API in an OpenStack component, there should be tests in
-tempest to exercise it in some way.
-
-
-Scope of these tests
---------------------
-
-Third party API testing should be limited to the functional testing of
-third party API compliance. Complex scenarios should be avoided, and
-instead exercised with the OpenStack API, unless the third party API
-can't be tested without those scenarios.
-
-Whenever possible third party API testing should use a client as close
-to the third party API as possible. The point of these tests is API
-validation.
