how to clear the execution result so far

[lvhu...@gmail.com]

Hi,

I was using the jacoco agent in tcpserver mode, and use ant to dump the execution result remotely. It seems that jacoco execution result is cumulative, i.e., result for each test run will be added to the existing result so far. So, how can I clear the current execution result so that I can get the 'clean' or 'ur' execution result of a particular test run?

Thanks.

See documentation of "dump" Ant task at https://www.jacoco.org/jacoco/trunk/doc/ant.html

set "reset" parameter to "true" to reset data on agent side

and

do not append it to same "destfile" or set parameter "append" to "false" to overwrite file.

Thanks Evgeny!
'reset' will reset data after dumping... so, in order to get the clean execution result, I guess I should dump (to reset), then launch my test, then dump again (to really get the execution result). Is there a better approach?

Thanks.

1. start your application

2. request dump with reset - you'll get execution data of startup

3. do your first test

4. request dump with reset - you'll get execution data of your first test

5. do your second test

6. request dump with reset - you'll get execution data of your second test

7. etc

 

Is there a better approach? 

This does exactly what you asked/wanted to do. So better in what? by which criteria? What does not satisfy you in the above approach?

The approach in my post dumps twice to get the result, so by "better" I meant if we can dump only once.

The approach you stated is essentially the same as mine, so I guess the answer is 'нет' - we already got what we need.

Thanks.

For step 2 you can just reset without actually requesting a dump. See documentation of „dump“ task.

Thanks Marc. So it will be something like 

    <jacoco:dump address="192.168.0.156" port="20279" reset="true" dump="false"/>
right?
