How to run JaCoCo for a sample code ?

[Yogesh Shinde]

I have taken all the code into eclipse from "https://github.com/jacoco/eclemma".
But how can I run JaCoCo for a sample code of mine ?

Thanks,
Yogesh

This repository is not JaCoCo, but EclEmma (the Eclipse plug-in for
JaCoCo). If your want to work on the JaCoCo source code the repository
is https://github.com/jacoco/jacoco

What exactly do you mean by "run a sample code of mine"?. If you want to
*use* JaCoCo there are pre-built distributions.

Problem:
Actually the objective of my thesis project is "Use of mock object in Code Coverage is considered".
1) There is a sample code given (also with test cases given which use mock objects).
2) I have to get and run the source code of code coverage tools (like JaCoCo).
3) This gives 100%(assumption) coverage for sample code which is called by test code using real and mock objects.
4) 100% includes code covered by (real objects) + (mock objects) + (real and mock objects).
5) My interest is into the code covered by (real objects) + (real and mock objects).
6) For this I have to find and modify the "code coverage tool" code.

 Example : Object A has method a1() which calls object B method b1() and object C method c1().
(i) When I run the tool it gives me 100%(assumption) code coverage.
(ii) When I mock the object C and again run coverage tool it gives 100% coverage.
(iii) When I mock the object C and use real object of C also, tools gives 100% coverage.

But after modifying code in "Code Coverage Tool" it should give me output as 50% for case (ii) above because I don't want coverage for code which is called by ONLY mock object.

My Query:
1) Is the code repository for "Code Coverage Tool" JaCoCo is https://github.com/jacoco/jacoco OR https://github.com/jacoco/eclemma ?
2) Which java file do I need to modify for NOT considering coverage for code called by mock objects ONLY ?

Thanks,
Yogesh

Hi,

answering your questions:

1) As stated before the repository for JaCoCo ("Java Code Coverage") is
https://github.com/jacoco/jacoco
2) JaCoCo does not consider the calling context when determine code
coverage for a praticular method or class. Probably there is quite a few
"java files" you need to modify to evaluate calling contexts.
