performed **inside the container**.
-The script **run_tests.sh** launches the test in an automated way.
-Although it is possible to execute the different tests manually, it is
-recommended to use the previous shell script which makes the call
-to the actual scripts with the appropriate parameters.
+Note: In Colorado release, the scripts **run_tests.sh** is now replaced with a
+new Functest CLI. One difference, is that tests run through the Functest CLI
+will always clean-up OpenStack resources. See the `Troubleshooting`_ section of this
+document, where this difference is discussed.
+
+The Functest CLI offers two commands (functest tier ...) and (functest testcase ... )
+for the execution of Test Tiers or Test Cases::

+ ['odl']
-It is located in *$repos_dir/functest/docker* and it has
-several options::
-
- ./run_tests.sh -h
- Script to trigger the tests automatically.
-
- usage:
- bash run_tests.sh [-h|--help] [-r|--report] [-n|--no-clean] [-t|--test <test_name>]
-
- where:
- -h|--help show this help text
- -r|--report push results to database (false by default)
- -n|--no-clean do not clean up OpenStack resources after test run
- -s|--serial run tests in one thread
- -t|--test run specific set of tests
- <test_name> one or more of the following separated by comma:
- vping_ssh,vping_userdata,odl,onos,tempest,rally,vims,promise,doctor,bgpvpn
-
- examples:
- run_tests.sh
- run_tests.sh --test vping_ssh,odl
- run_tests.sh -t tempest,rally --no-clean
-
-The *-r* option is used by the OPNFV Continuous Integration automation mechanisms
-in order to push the test results into the NoSQL results collection database.
-This database is read only for a regular user given that it needs special rights
-and special conditions to push data.
-
-The *-t* option can be used to specify the list of a desired test to be launched,
-by default Functest will launch all the test suites in the following order:
-
- 1) vPing test cases
- 2) Tempest suite
- 3) SDN controller suites
- 4) Feature project tests cases (Promise, Doctor, SDNVPN)
- 5) vIMS suite
- 6) Rally suite
Please note that for some scenarios some test cases might not be launched.
-Functest calculates automatically which test can be executed and which cannot given
-the environment variable **DEPLOY_SCENARIO** to the docker container.
-
-A single or set of test may be launched at once using *-t <test_name>* specifying
-the test name or names separated by commas in the following list:
-*[vping_ssh,vping_userdata,odl,onos,rally,tempest,vims,promise,doctor]*.
-
-Functest includes cleaning mechanism in order to remove
-all the OpenStack resources except what was present before running any test. The script
-*$repos_dir/functest/utils/generate_defaults.py*
-is called once by *prepare_env.sh* when setting up the Functest environment
-to snapshot all the OpenStack resources (images, networks, volumes, security groups,
-tenants, users) so that an eventual cleanup does not remove any of this defaults.
-
-The *-n* option is used for preserving all the possible OpenStack resources created
-by the tests after their execution.
-
-The *-s* option forces execution of test cases in a single thread. Currently this
-option affects Tempest test cases only and can be used e.g. for troubleshooting
-concurrency problems.
+For example, the last example displayed only the 'odl' testcase for the given
+environment. In this system the deployment does not support the 'onos' SDN
+Controller Test Case; for example.
+
+**Important** If you use the command 'functest tier run <tier_name>', then the
+Functest CLI utility will call **all valid Test Cases**, which belong to the
+specified Test Tier, as relevant to scenarios deployed to the SUT environment.
+Thus, the Functest CLI utility calculates automatically which tests can be
+executed and which cannot, given the environment variable **DEPLOY_SCENARIO**,
+which is passed in to the Functest docker container.
+
+Currently, the Functest CLI command 'functest testcase run <testcase_name>', supports
+two possibilities::
+
+ * Run a single Test Case, specified by a valid choice of <testcase_name>
+ * Run ALL test Test Cases (for all Tiers) by specifying <testcase_name> = 'all'

The reason to include this cleanup meachanism in Functest is because some
test suites such as Tempest or Rally create a lot of resources (users,
tenants, networks, volumes etc.) that are not always properly cleaned, so this
function has been set to keep the system as clean as it was before a
full Functest execution.

Automated testing
