Jacoco requires Main method!

[Shekhar]

Hello,

I am trying to find coverage of my automation testing code using Jacoco-ant plugin. But the issue is my code base doesn't contain any Main method, so when I run the Jacoco code coverage over it, it shows -"No Main method found, please declare your main method as ...".
Is it possible for Jacoco to provide coverage when there are classes without any main method or in any way is it possible to skip the check for main method?

Thanks
Shekhar

Hi Shekhar,

JaCoCo does not require a main method. Actually it is the JVM which requires a main method to execute any Java program.

1) How do you run your application without JaCoCo?
2) What did you try to run the application with JaCoCo?

It will be helpful if you provide your Ant scripts for both cases.

Hey Marc,

I am actually using ant to build the code base and have integrated Jacoco to check the coverage and generate the report, the problem is the code base mostly consists of Functional testing codes, which don't use main but are rather run using Junit annotations (@Test), I am unable to get the JVM to execute those @Test methods and get the coverage. 

I have attached the part of ant build file which includes Jacoco.

Thanks

Hi Shekar,

and how did your Ant file look before you added JaCoCo (my question 1)?

Hey Marc,

Actually I created this jacocoTests target newly. Earlier it was cobertura based so we decided to shift from cobertura to Jacoco.

I am having trouble in getting the code containing @Test annotation to run.

Thanks

Is it that hard to precisely answer Marc question and show

In absence of above details, one can only guess how you execute your tests and can only suggest you to read documentation - https://www.jacoco.org/jacoco/trunk/doc/ant.html

JUnit tests in Ant typically executed using junit task - https://ant.apache.org/manual/Tasks/junit.html

And above documentation contains example for JUnit:

<jacoco:coverage>

    <junit fork="true" forkmode="once">

        <test name="org.jacoco.examples.HelloJaCoCoTest"/>

        <classpath>

            <pathelement location="./bin"/>

        </classpath>

    </junit>

</jacoco:coverage>

Or one can also suggest to use Google. There are plenty of examples in internet - https://itaffinity.wordpress.com/2012/06/05/generating-and-customizing-junit-and-code-coverage-reports-with-ant/

If above doesn't help, then please finally provide more details by answering the question of Marc.

Thanks
