Scalability Testing: Decompose Registry testing

[Bolodya1997]

Test plan

Use cases:

1. NSMgr registers Endpoint on Registry.
2. NSMgr updates Endpoint on Registry.
3. NSMgr unregisters Endpoint from Registry.
4. NSMgr creates a find request to Registry.
5. NSMgr creates a watching find request to Registry.
6. Registry unregisters expired Endpoint from itself.

Test scenarios:

1. NSMgr registers Endpoint on Registry:
   • Setup
     1. Start Registry.
   • Test
     1. Start N fake NSMgrs each registering E Endpoints.
2. NSMgr updates Endpoint on Registry:
   • Setup
     1. Start Registry.
     2. Start N fake NSMgrs each registering E Endpoints with T update time.
   • Test
     1. Wait T time for updates.
3. NSMgr unregisters Endpoint from Registry:
   • Setup
     1. Start Registry.
     2. Start N fake NSMgrs each registering E Endpoints.
   • Test
     1. Unregister endpoints.
4. NSMgr creates a find request to Registry:
   • Setup
     1. Start Registry.
     2. Start N fake NSMgrs each registering E Endpoints.
   • Test
     1. Create F find requests from each NSMgr to Registry.
5. NSMgr creates a watching find request to Registry:
   • Setup
     1. Start Registry.
     2. Start N fake NSMgrs each registering E Endpoints.
   • Test
     1. Create W watching find requests from each NSMgr to Registry.
6. Registry unregisters expired Endpoint from itself:
   • Setup
     1. Start Registry.
     2. Start N fake NSMgrs each registering E Endpoints with T expiration time.
   • Test
     1. Wait T time for unregisters.

Tasks

1. Create fake NSMgr CMD.
