Exclusion of method (main)

[Brandon Largeau]

Hello,

I searched a lot about this but nothing really work.

I'd like to exclude "main(String[] args)" from the coverage because this isn't really a functionnality to test.

I'm using jacoco through Gradle.

Why do I want that ? Because main isn't covered by the tests (since there's nothing to test in it).

Should I put a call to main in the JUnit test ?

I tested @Generated or even @ExcludeFromCodeCoverage but doesn't work.

Thanks you!

Hi,

the @Generated annotation needs to be of retention CLASS or RUNTIME.

 Hint: javax.annotation.Generated which ships with the JDK has retention SOURCE and does not work for JaCoCo.

In an addition to what was already written by Mark:

Please also note that we do not recommend to use annotations for manual tagging - they are not designed for this,

as written on page https://github.com/jacoco/jacoco/wiki/FilteringOptions

A Generated annotation should only be used for code actually generated by compilers or tools, never for manual exclusion.

Yes, you can do this.

Or your main method can be the only method of a class and so you can exclude the whole class.

Or you can simply ignore the fact that the main method shows as uncovered.

Hello,

Thanks for the answers !

So I think there's no way to exclude a method fromt the coverage using Jacoco I think.

I'll put the main method alone and exclude it then, thanks for the idea.

Any tuto on how to achieve that using Gradle ? I already tested some idea from the internet but nothing actually work.

Thank you for your help.
