|
15 // Overview: |
|
16 // Tests the Client/Server architecture of the Symbian platform. |
|
17 // Tests that messages are completed when a server terminates. |
|
18 // API Information: |
|
19 // CSession2, CServer2, RSessionBase. |
|
20 // Details: |
|
21 // - Create and start a server thread. Verify results are as expected. |
|
22 // - Create and close client sessions to enforce granularity expansion. |
|
23 // - Open and close a session and verify that the heap is OK. |
|
24 // - Open a connection specifying 0 message slots for the session and verify |
|
25 // that the server returns KErrNone. |
|
26 // - Create lot of timers to eliminate kernel granularities. |
|
27 // - Create a client session and validate kernel heap is ok if client is killed. |
|
28 // - Create a client session and validate kernel heap is ok if server is killed |
|
29 // when client has outstanding request to server. |
