The online tester provides the following facilities for testing UAPs:

1. Client UAP simulator
   Simulates client UAP processing so that a server UAP can be tested without a client UAP.
   
2. Server UAP simulator
   Simulates server UAP processing so that a client UAP can be tested without a server UAP.
   
3. MCF simulator
   Simulates message send and receive processing controlled by TP1/Message Control so that an MHP or an SPP called by service requests from the MHP can be tested without TP1/Message Control.
   
4. Disabling resource update
   Disables update processing of resources so that the test UAP does not update resources used by applications.
   
5. Operating command simulator
   Simulates the processing of operating commands issued by a test UAP.
   
6. Tester file creation and editing
   Creates tester files needed for each simulation and outputs them in an edited format.
   
7. UAP trace collection
   Collects UAP trace information for the UAP being tested.
   
8. Merger and editing of UAP trace information
   Merges UAP trace information collected in multiple files and edits the information for output.
   
9. Send message editing
   Collects send messages from test UAPs and edits the messages for output.
   
10. Debugger interlocking
    Executes a UAP to be tested under control of the debugger.
