Scalability Testing: Decompose NSMgr testing

[Bolodya1997]

Test plan

Use cases:

1. Endpoint registers on NSMgr.
2. Endpoint updates itself on NSMgr.
3. NSMgr unregisters expired Endpoint from itself.
4. Forwarder registers on NSMgr.
5. Forwarder updates itself on NSMgr.
6. NSMgr unregisters expired Forwarder from itself.
7. Client sends request to NSMgr.
8. Client sends refresh request to NSMgr.
9. Client closes connection on NSMgr.

Test scenarios:

1. Endpoint registers on NSMgr:
   • Setup
     1. Start fake Registry (just returning OK to all Register/Unregister events).
     2. Start NSMgr.
   • Test
     1. Start E Endpoints each registering itself on NSMgr.
2. Endpoint updates itself on NSMgr:
   • Setup
     1. Start fake Registry (just returning OK to all Register/Unregister events).
     2. Start NSMgr.
     3. Start E Endpoints each registering itself on NSMgr with T update time.
   • Test
     1. Wait T time for updates.
3. NSMgr unregisters expired Endpoint from itself:
   • Setup
     1. Start fake Registry (just returning OK to all Register/Unregister events).
     2. Start NSMgr.
     3. Start E Endpoints each registering itself on NSMgr with T expiration time.
   • Test
     1. Wait T time for unregisters.
4. Forwarder registers on NSMgr:
   • (1)
5. Forwarder updates itself on NSMgr:
   • (2)
6. NSMgr unregisters expired Forwarder from itself:
   • (3)
7. Client sends request to NSMgr:
   • Setup
     1. Start NSMgr.
     2. Start E Endpoints each registering itself on NSMgr.
   • Test
     1. Start C Clients each requesting for E network services (Endpoints).
8. Client sends refresh request to NSMgr:
   • Setup
     1. Start NSMgr.
     2. Start E Endpoints each registering itself on NSMgr.
     3. Start C Clients each requesting for E Endpoints with T refresh time.
   • Test
     1. Wait T time for refreshes.
9. Client closes connection on NSMgr.
   • Setup
     1. Start NSMgr.
     2. Start E Endpoints each registering itself on NSMgr.
     3. Start C Clients each requesting for E Endpoints.
   • Test
     1. Cancel Clients.
10. NSMgr closes expired connection with Client.
    • Setup
      1. Start NSMgr.
      2. Start E Endpoints each registering itself on NSMgr.
      3. Start C Clients each requesting for E Endpoints with T expiration time.
    • Test
      1. Wait T time for closes.
