Which is the correct code structure to be followed for getting the best output using TestModules in Canoe?

I am using CANoe 10.0 to do some Diagnostic testing and I have to generate reports for the tests. So, I am using Test Setup to create my test cases using CAPL. I know that the test starts from the function "MainTest". After this, I don't know how to structure my test case and which functions to use to get the correct format in the report. For example, I want to send a Diagnostic request and expecting a particular response. I want to be able to show in the report, the sending of the message, what response was received and what response was expected. Based on this, the verdict should be displayed.
