on testing factor nodes

[ghost]

I looked at testEqualityNode and think it's great. good job! Some comments/suggestions:

• In testEqualityNode, on line 23, 24, I woudl prefer to see

  EXPECTED_VAR = 1/(1/5 + 1/4); EXPECTED_MEAN = EXPECTED_VAR * (10/5 + 20/4) ;

or, better yet, set m_a=10 and V_a = 5 at the top of the function and work with teh variables. The reason is that I like to see where the EXPECTED_VAR and EXPECTED_MN comes from.

• (for later, low priority). Let's add some comments to the assertions in the test functions that relate them to Loeliger tables. For instance, in testEqualityNode, assertion at line 28 shoudl get comment % LOE2007- II.4) because it tests eq II-4 in Loeliger 2007. Better yet, I dont know how to do this, but it woudl be could to find the test assertions by a function like findAssertion('Loe2007-II.4').
• (low priority) the test fucntion testaddNode has dependencies on other toolbox fucntions like network.addEdge. In the long term, if the test suite expands this could lead to problems. I dont knwo how to resolve that either. My colleage Joris here has a matlab tool called muice that's basically the matlab equivalent of this: http://code.google.com/p/google-guice/ (has something to do with dependency injection. Let me know if you want ot know more.

nice job!

concerning the findAssertion, I guess it would be too much. How about just adding comments like "Loeliger 2007" in the test body and then using Ctrl+F|Ctrl+S?

I'm fine with your resolution on 'findAssertion'.
