Hello, I initially sent the following message to the boost-dev mailing list, but I'm thinking this might reach more potential users here on boost-users. Would a library for mock objects be of interest ? The documentation can be found here : http://mat007.users.sourceforge.net/boost_mock/ An archive is also available for download there : http://sourceforge.net/projects/mat007.u/files/boost-mock.zip It's been converted from turtle (http://turtle.sourceforge.net/) which was mentioned on the mailing-lists a couple of times in the past. There is a catch in that it needs Boost.Test from the release branch and doesn't compile with the trunk. The changes are minimal though and I can provide a patch if anyone is interested. Is anyone already using the library who would like to see it in Boost ? Or is anyone using another mock object library who wants to give it a go ? Or even better has anyone tried it and decided to user another library who would like to comment on it ? I would be highly interested in any feedback ! Thank you, MAT.
Really good work. I like the interface and the boost unit test integration. I don't have time to test it now, but i defenitly would love to see it in boost. 2013/9/20 Mathieu Champlon <m.champlon@free.fr>

Hi Mathieu, Can you please summary here in few paragraphs: * What exactly you want to test? * What exactly you want to mock? * How do you want to record your expectations? * How do you want to test against these expectations? * Can you show some concise example if using this library? What do I start with? How do I write a test case? Regards, Gennadiy
Hello, It could be of interest, but there is already google-mock out there, and it is a good tool, I see no reason why to have another mock library. On Jan 13, 2014 5:25 AM, "Gennadiy Rozental" <rogeeff@gmail.com> wrote:

While older versions of google mock could be used independent of google test, it seems that the current versions of google mock have a link dependency on google test. I don't want to link in google test just to use google mock. Have you tried using current versions of google mock without using google test? -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

I didn't check if google.mock could be used separately from google.test. In fact, I am very comfortable with using both of them together. On Jan 20, 2014 6:42 AM, "Richard" <legalize+jeeves@mail.xmission.com> wrote:

Hi Mathieu,
Can you please summary here in few paragraphs:
* What exactly you want to test?
It's probably up to the user to decide what needs to be tested. Any piece of code (sub-system) which interacts with another (the rest of the system) can be tested, with a few restrictions. For instance the library won't be able to inject a different function implementation without some kind of hook (e.g. a function pointer passed to the code under test).
* What exactly you want to mock?
Classes, concepts, functions and function objects are supported, see http://mat007.users.sourceforge.net/boost_mock/boost_mock/reference.html#boo...
* How do you want to record your expectations? * How do you want to test against these expectations? * Can you show some concise example if using this library? What do I start with? How do I write a test case?
Does the motivation example from the introduction answer your questions ? http://mat007.users.sourceforge.net/boost_mock/boost_mock/motivation.html I'll copy it here if you want to discuss it: class view { public: virtual void display( int result ) = 0; }; class calculator { public: calculator( view& v ); void add( int a, int b ); // the result will be sent to the view 'v' }; BOOST_MOCK_BASE_CLASS( mock_view, view ) // declare a 'mock_view' class implementing 'view' { BOOST_MOCK_METHOD( display, 1 ) // implement the 'display' method from 'view' (taking 1 argument) }; BOOST_AUTO_TEST_CASE( zero_plus_zero_is_zero ) { mock_view v; calculator c( v ); BOOST_MOCK_EXPECT( v.display ).once().with( 0 ); // expect the 'display' method to be called once (and only once) with a parameter value equal to 0 c.add( 0, 0 ); } Cheers, MAT.

If I was developing a mocking framework, I'd rely on some classic Unit Testing/Mocking examples to support the motivation, like those about logging or sending e-mail. Simply, I'd translate Roy Osherove's introductory examples: http://www.youtube.com/watch?v=fAb_OnooCsQ Those are so well known within testing community, they are almost idiomatic, hence best for selling a framework.

Hi, Thanks for the link. You're right that a real world use case is likely to be a better example. I'll try and rework the motivation/introduction page. Thank you! Regards, MAT.

If I had known about Turtle when I was writing my tutorials, I would have used it instead of a hand-written fake when talking about creating UI dialogs with TDD: <http://legalizeadulthood.wordpress.com/2009/07/05/c-unit-tests-with-boost-test-part-4/> I think it would have made things a little easier to explain and certainly save work in that you don't have to make the test doubles by writing lots of boiler plate code. I agree that this is the area where Turtle's documentation could use the most improvement -- real-world examples that get away from just showing the syntax and show the mocks being used in a meaningful way. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
