Ok I could not see the MW or methods as object use but now I get it.
So the granularity is already good.
I would really like the support for coverage in Pharo ecosystem and not only on build system.
I would really like that we push tests to the next level :).

First, configuration looks for classes and packages ( look at .smalltalk.ston file )
Second, you take all the methods inside the classes and packages.
If a method is an extension ( for instance, method A of class C is under package P. But class C is under package P2), then select all the methods of the class of the method ( this logic is under discussion in two issues of SmallTalkCI.
Third, SmallTalkCI wraps each method ( install a wrapper in the method's class that is called instead of the real method ).
When a wrapper is called, marks a Boolean to true, and calls the original method.
Finally, the coverage is the number of covered methods marked as true compare to the total number of covered method.
( Note : the wrapping is not done using reflectivity whereas it can be a good idea ? )

Thanks I could not find it.
I read the code and it is still unclear what is the logic. I could not figure out what we get lines here.
I would like to resurrect the AST interpreter to get some information on AST level coverage.
What is see is that so far this is a heuristic that is used in SmalltalkCI.

Hi
I would like to know exactly how the test coverage is computed.
I read all the code of SmalltalkCi and I could not find it.
