[Nmock-general] Re: Some clarifications required on NMock

[Owen R. <OR...@th...>]

ah i see... you're looking for a way to inject mocks for 
acceptance/regression/integration testing...
while you can use nmock to accomplish this sort of task, the framework was 
not designed with this in mind.  nmock, like most mocking frameworks is 
intended to help drive the design of code using unit tests.  it is used to 
design and test the interaction between dependent objects, not for 
layer-based testing.  nat pryce has a very nice blog entry on the subject: 
http://nat.truemesh.com/archives/000342.html

that said, here's one suggestion for how you can use nmock to accomplish 
your task.  if you can avoid having to work with persistent mocks, it will 
make your life much easier.  the challenge is to figure out how to inject 
in-memory mocks into your code.  my recommendation is to try using 
picocontainer and constructor-based dependency injection; however, this 
may require a radically change to your architecture.  alternately, you can 
use service locators (which is kind of like what you already have). martin 
fowler has a nice article describing these two approaches:

owen.

Hi Owen,

Thanks for the reply. Actually our development code will look like the
below one.


class XFactory
{
      //.... some code

      Public X GetXInstance
      {
            get
            {
                  if(InUnitTest)
                  {
                        retyrn return XMock
                  }
                  else
                  {
                        return realX
                  }
            }
      }
}

I hope this will gives the information required.

with regds,
vasu

hi vasu,

> Is it possible to save the Mock class generated by Nmock.
currently no (at least as far as i understand your question).  could you
please explain further why you might want to do this?  i'm not sure if i
understand what you mean by "later time compilation and customization".

cheers,
owen.

ps. in future, please address your queries to the list
(nmo...@li...) rather than directly to the
maintainers.

Hi,

We have a question on NMock. Is it possible to save the Mock class
generated by Nmock. Whether the Mock classes will be available in the disk
for later time compilation and customization. Pls give me these answers.
