jacoco test reports are cleared

[yezi...@gmail.com]

Hi!

I am using the Jacoco Agent with tomcat to get my test reports and I have got a problem.
when I change some java src and restart tomcat server, next time I get my Jacoco test reports ,the coverage rate of class which I have changed before are cleared.

Is there any way can help to solve my problem?

Thanks.

Hi,

this is exactly how JaCoCo works: coverage data of different versions of
a class cannot be merged.

hi marc

Thanks for your reply.

Our project need a coverage rate report during Unit Test stage.This stage is unstable and has a lot of changes in src.Can you improve Jacoco to solve our problems ?

Many thanks.

Hi,

especially when you have a lot of changes in your code base you should
definitely run all your unit tests again. Best practice would be to
automate unit test execution, it's always "unit test stage" ;-)

We had this discussion before here: It definitely doesn't make sense and
there no reasonable way to merge the execution paths from one version of
a class to a different version.
