Pex From Code (Z3, Dynamic Symbolic Execution) RRS feed

  • Question

  • I have a simple method, for example:

    public int MyMethod(int a){
                if (a == 0)
                    return 1;

                else
                    return 2;
    }

    Is there a class in Microsoft.Pex.Framework.dll which will solve the path conditions for me if I pass this method to it?

    I am trying to use Microsoft's bit of handy work so that I do not have to go to Z3 directly.

    Thank you.

    I'm afraid not, according to the IntelliTest official doc. which does not mention any class that could make it.

    As Jack had suggested, you could post a thread on stack overflow where the PEX team there might give you some other advice.

    Your understanding and cooperation will be grateful.

    Have a good day:)

  • I am trying to find the paths for variable a in the above method.

  • I do also have the method 'MyMethod' in a syntax tree. I can place it in any other data structure but I thought there might be a simple conversion for a syntax tree to Z3 notation.

  • I want to make the call to Intellitest myself and not use the user interface of Visual Studio for it. I am looking for direct access into the Dynamic Symbolic Execution part of Intellitest so that I can pass it some form of code or call and ask it what the paths are.

    I could do this by calling Z3 but then why go through all that trouble if Microsoft already figured that out for me.
