How to Test OpenStack Keystone or Identity Deployment With Tempest

1)
Install OpenStack using devstack and make it running
http://www.youtube.com/watch?v=AdrbYP7utDE

2)
#mkdir tempest_test
#cd tempest_test
#git clone https://github.com/openstack/tempest.git
#git checkout stable/branch_you_need



3)
You will get dependency errors when running following commands
#nosetests -v tempest

4)
Create virtualenv and install all dependencies
#./run_tempest.sh

5)
Activate virtualenv
#ls -a
#source .venv/bin/activate

6)
Find command help
#nosetests -v tempest --help

7)
Stop running tests after the first error or failure (use -x or --stop option)
#nosetests -vx tempest
or
#nosetests -v tempest --stop

8)
ConfigFilesNotFoundError: Failed to read some config files: /etc/tempest/tempest.conf

=============Solution/Fix================

a)
Goto
#cd tempest_test/tempest/etc
#vim tempest.conf.sample
Read "tempest.conf.sample" file and understand different config options

b)
Copy tempest.conf.sample to /etc/tempest/tempest.conf
#sudo mkdir /etc/tempest
#sudo cp tempest.conf.sample /etc/tempest/tempest.conf

9)
Run only the tests inside the module test_users.py
#nosetests -vx tempest.api.identity.admin.v3.test_users.py

10)

    if 'tokens' not in auth_url:
TypeError: argument of type 'NoneType' is not iterable

=============Solution/Fix================

#sudo vim /etc/tempest/tempest.conf

11)
Run only the tests inside the module test_users.py

    raise exceptions.InvalidConfiguration('you must specify a v3 uri '
InvalidConfiguration: Invalid Configuration
Details: you must specify a v3 uri if using the v3 identity api

=============Solution/Fix================

#sudo vim /etc/tempest/tempest.conf
[identity]
uri=http://127.0.0.1:5000/v2.0/
uri_v3=http://127.0.0.1:5000/v3/

[identity]

uri_v3=http://127.0.0.1:5000/v3/

15)
(Working)
Run only the tests inside the module test_users.py
#nosetests -vx tempest.api.identity.admin.v3.test_users.py

16)
(Summary)
So, The minimum configuration to run identity tempest test

a)
#sudo vim /etc/tempest/tempest.conf
[identity]
uri=http://127.0.0.1:5000/v2.0/
uri_v3=http://127.0.0.1:5000/v3/
admin_password=openstack

OR

[identity]
uri=http://127.0.0.1:5000/v2.0/
uri_v3=http://127.0.0.1:5000/v3/
admin_username=admin
admin_tenant_name=admin
admin_password=openstack

b)
Run only the tests inside the module test_users.py
#nosetests -vx tempest.api.identity.admin.v3.test_users.py
OR
#nosetests -vx tempest.api.identity.admin.v3.test_users
OR
nosetests -vx tempest.api.identity.admin.v3.test_users.py:UsersV3TestJSON.test_list_user_projects
OR
nosetests -vx tempest.api.identity.admin.v3.test_users:UsersV3TestJSON.test_list_user_projects

======
Note:
-vxl 
x ---> Stop running tests after the first error or failure
l ---> Run test in Debug mode: So we can see better error message
