The offline 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 for testing an MHP or an SPP called by service requests from the MHP.
   
4. File service simulators
   Simulate the DAM service and TAM service for testing UAP access to DAM or TAM files.
   
5. OpenTP1 function simulator
   Simulates processing of OpenTP1 functions by using the corresponding simulation functions that have the same names as the OpenTP1 functions.
   
6. Operating command simulator
   Simulates the processing of operating commands executed by a test UAP.
   
7. Tester file creation
   Creates the tester files required when using the simulators.
   
8. Continuous command execution
   During testing, continuously executes the offline tester subcommands set in a file.
   
9. Debugger connection
   Runs test UAPs under debugger control.
   
10. Collection of offline tester trace information
    Collects trace information for the UAP being tested.
