如何以编程方式更改方法

Question

I am writing a test application to test an Operation Contract in the a service

Test client:

here is how I am making a call from my test to get the returned bool value

   bool operateResult =  TestContext.ServiceOperator.Operate(ref Inputmessage);

Service:

The operate method above calls another method

      bool  Operate(){
        OperatorProcess(msg, interface);
      }

        private bool OperatorProcess(ref Message MessageData, string SendInterface)
        {
        parse(message);
        validate(message);
        Transfer(message);
        }

From my test my goal is to test the operator method but in the process operator I don't want to reach the Transfer(message) I want it to exit right after validate and get the result.

How can I programmatically modify it from my test application? Thanks

Note : the transfer method send the parsed and validated method to another service and I want to stop it from sending my request to that service.

Answer 1

Why don't you try extending the class that contains the OperationProcess function and overriding the function then calling your overridden function that only does the few parts you care about... You can keep the parts in your function that you care about and only the functionality you need to test for.

You can declare a global boolean variable test then set it to true during testing and set it to false during production, then you method will look similar to

private bool OperatorProcess(ref Message MessageData, string SendInterface)
{
    parse(message);
    validate(message);
    if(!TEST)  Transfer(message);
}

Alternatively, if you don't want to create a global variable, then you can just add a parameter to the method signature

private bool OperatorProcess(ref Message MessageData, string SendInterface, bool performTransfer)
{
    parse(message);
    validate(message);
    if(performTransfer)  Transfer(message);
}
