Test cases need to support variable environment args and values

[yeti9990]

Need to add .env support or OS environment variables for test cases to work in different labs and environments.

Minimally we'll need to support:

• grid_mgr (either hostname or IP)
• ssl_verify (either False or '/path/to/certfile')
• username / password credentials
• certificate (a user certificate for CAS testing, this will be '/path/to/usercert')

there may be others as well.

This suggests using pytest-env as the best method.

The solution is to install:

• pytest-env
• pytest-dotenv

use either the pytest.ini or create a .env which i think is best. The pytest.ini will override .env or os environ.

my .env looks like:

GRID_MGR=192.168.40.60
USERNAME=admin
PASSWORD=infoblox
SSL_VERIFY=False
WAPI_VER=2.12
