Does anyone has any idea as to how can we configure code coverage for storm topologies?
We have about 5 topologies and we have to setup code coverage for these topologies.
Does Jacoco, cobertura works?
Was finally able to get coverage using Jacoco.
I passed arguments to topology submission "-javaagent:/var/lib/rdp/jacoco/org.jacoco.agent-0.8.1.jar=destfile=/var/lib/rdp/jacoco/jacoco.exec,includes=com.ABC.*".
To generate the report I have to kill the topology and then generate html report from coverage file. Also to overcome killing part, am sending continuous coverage to a 3rd server.

Try to use python green to control python (2.7.x) code quality, and integrated it within jenkins.
In nose, there is --with-xunit parameter to generate nosetests.xml unit test.
In coverage, it is possible to use xml paramter to generate like coverage.xml coverage report.
Both are very good to be integrated with jenkins.
Do you know how to achieve this in green ?
At the moment, Green does not support any means of producing xml output or integrating with Jenkins.
However, subunit support is planned. Once subunit support is in place, you should be able to hook it up to Jenkins.
I want to instrument my entire application, launch it, and then execute some system test runs. How much slower will my application run (manually testing so no ant JVM launch issues)? 1.5X, 2X, 10X, 20X,...
The following studies show Cobertura adds from 30% to 100% to execution time.

I'm trying to get Sonar IT Code coverage to work for me when my unit tests are "covered" via Emma.
My situation :
(1) I have unit tests that make extensive use of JMockit. Removing JMockit is not an option. I want to get unit test coverage reports for these tests.
(2) I have integration tests that simply run the core server side portion of the app (its a Spring web app) with different input scenarios. I want IT code coverage reports for this.
For part (1) I have chosen to use Emma for my unit test coverage mainly because I was having issues with Jacoco and JMockit working together due to both tangling each other up while instrumenting the java classes on the fly. There are some issues with these tools working together - with no solution that I saw as being reliable and non-invasive to the unit tests themselves. So in the end, I chose to use Emma as its does "offline instrumentation" to perform the code coverage. Jacoco does offline as well, but I could not get Sonar to pick up its results in this mode (Maybe I forgot a semi-colon :-) ).
For part (2) [ the IT code coverage part ] I have only seen the ability to specify the following property
sonar.jacoco.itReportPath=build/coverage/jacoco.exec
I can only assume, we need to use Jacoco to instrument the IT tests? Correct me if I'm wrong. So technically I can use Jacoco for this part of the tests because my integration tests do not use JMockit.
This is what I did. I have a separate ant task that recompiles the code base (stripping out the Emma instrumentation) and then repackages the application and runs the jacoco:coverage tool against my integration tests.
Problem is.. my unit tests are Emma based.. so how do you tell Sonar to use the Emma plugin for the Emma unit tests and the Jacoco plugin for the IT tests? Can this even be done?
Here is how I set up my Sonar properties:
sonar.test=test
sonar.sources=src
sonar.binaries=build/compile
# The value of the property must be the key of the language.
sonar.language=java
# Encoding of the source code
sonar.sourceEncoding=UTF-8
sonar.host.url=http://localhost:9000
sonar.dynamicAnalysis=reuseReports
sonar.java.coveragePlugin=emma
sonar.core.codeCoveragePlugin=emma
sonar.jacoco.itReportPath=build/coverage/jacoco.exec
sonar.emma.reportPath=build/coverage
sonar.junit.reportsPath=build/test/report
sonar.surefire.reportsPath=build/test/report
My ant build runs the Emma unit tests (output in Emma form) and then the IT tests are run with the output to the jacoco.exec file. Then I upload to Sonar.
I get the unit test coverage stats - not the IT stats. I'm not really surprised with the results.
But does anyone have an idea where I made a wrong turn?
You already made some efforts using jacoco for your unit-test-coverage. I would continue trying to make that solution work and maybe post your difficulties with that here.
I recommend to try using jacoco for both coverage reports, because Integration-Coverage can only be analysed with jacoco, as you can read here:
http://www.sonarqube.org/measure-coverage-by-integration-tests-with-sonar-updated/
I have consulted the documentation of sonarqube and configuration-websites and did not find a possibility to use different coverage plugins.
You can find the documentation for
Unit-Test-Coverage here: http://docs.codehaus.org/display/SONAR/Code+Coverage+by+Unit+Tests+for+Java+Project
and for Int-Test-Coverage here: http://docs.codehaus.org/display/SONAR/Code+Coverage+by+Integration+Tests+for+Java+Project
`No valid coverage data available
Tracking and trending code coverage works best when like is compared with like. In this regard it is best to only track builds when all unit tests are passing.
This plugin will not report code coverage until there is at least one stable build.`
what should i do to have a rails stats report
#krs - From what you've said in your comments, you are correct.
rails stats only provides code coverage metrics for tests at that point in time. rails stats does not intend to keep data between builds and report test results vs. code converage.
You can connect your CI to an external service to see test coverage vs. test results. (EG, https://coveralls.io).
Please add coverage.xml file outside the project.It works fine for me.
Reasking my older question:
Java test coverage: who covers what?
Background: I look at sonar's coverage report for a class and want to know, which test contributes to the coverage of a specific line / branch, so that it easy to got to that test and add the test for the newly introduced if-branch.
Are there other (preferably free) alternatives to clover in the IDE? Perhaps even such that they can be included into sonar ?
Or maybe tricks to enhance, accumulate information with some scripting in emma-reports ?
Or even further, patch emma or cobertura to log the required info (instead of logging a "1" for counting, one could well log the names of class under test and the test, I assume)
Thanks!
You should definitely give a try to JaCoCo. Its integration with Sonar allows to benefit from new features, for example :
merge coverage by unit and integration tests. See http://www.sonarsource.org/sonar-3-3-in-screenshots/
track the relations between tests and tested code (since sonar 3.5). You can find a screenshot on the documentation page: http://docs.codehaus.org/display/SONAR/Resource+Viewer#ResourceViewer-CoverageTab
