The clients registry is a singleton. In Tempest it's filled with
|
|
content from configuration. When testing Tempest lib classes without
|
|
configuration it's handy to have the registry setup to be able to access
|
|
service client factories.

|
This fixture sets up the registry using a fake plugin, which includes all
|
|
services specified at __init__ time. Any other plugin in the registry
|
|
is removed at setUp time. The fake plugin is removed from the registry
|
|
on cleanup.
