Jacoco integration (regression) test not showing coverge results

[Harriet Severino]

I am running a regression test for a web-app and need to collect code coverage. I followed these steps to setup:

https://github.com/Accenture/adop-cartridge-java/issues/12

Rebuild the app jar file with jacoco activated and rsync'ed to server

Restarted tomcat using the javaagent:

-javaagent:/foo/sonarqube/jacoco-0.7.8/lib/jacocoagent.jar=output=tcpserver,jmx=true"

I am using the example from http://www.eclemma.org/jacoco/trunk/coverage/org.jacoco.examples/org.jacoco.examples/MBeanClient.java.html to reset and dump the data.

Run the reset command

Run the regression test

Run the dump command

I get a file jacoco-client.exec output. It is a bit bigger than the output file from my unit-test maven run. Therefore, I assume I am correct upto this point.

Sync data file (jacoco-client.exec) to sonar-system, using rsync

sonar-project.properties 

# Required metadata

sonar.projectKey=java-sonar-runner-simple

sonar.projectName=FOO Regression Test

sonar.projectVersion=FOO-2.2

# Comma-separated paths to directories with sources (required)

sonar.sources=src

# Language

sonar.language=java

Run sonar-runner

$ sonar-runner -Dsonar.host.url=http://dev-devtools-cps01.kendall.corp.akamai.com:9000/sonar

I get the run in sonarqube, but no coverage data is shown. How do I get the coverage data into sonarqube, assuming I collected coverage data.

I run unit tests via the maven plugin and get coverage in sonarqube, so I can get coverage %s.

Hi,

First, the customary courtesies (Hi, Thx, ...) are appreciated here. :-)

Do you see anything in your analysis log that relates to JaCoCo? I'm looking at a log from one of our internal projects, & I see:

[INFO] Sensor JaCoCoSensor [java]
[INFO] Analysing /home/travis/build/SonarSource/sonar-rule-api/target/jacoco.exec

Also, I don't understand your last sentence

I run unit tests via the maven plugin and get coverage in sonarqube, so I can get coverage %s.

Is this on a separate project?

I have rsync-ed the jacoco-client.exec file from the server under test. 

sonar-runner.properties sets:

sonar.jacoco.itReportPath=target/jacoco-client.exec

# set location of code under test

sonar.sources=/project/src/main/java/com/akamai/cps

# set location of tests

sonar.tests=/project-regression/src/main/java/com/akamai/cps/testing/

sonar.language=java

I run

sonar-runner -Dsonar.host.url=http://fqdn.sonar.server:9000/sonar

In the output I see:

13:49:59.974 INFO  - Sensor SurefireSensor (done) | time=478ms

13:49:59.974 INFO  - Sensor JaCoCoSensor

13:50:00.139 INFO  - Sensor JaCoCoOverallSensor (done) | time=129ms

How do I get class files?

I compile the war file in the directory, on this build server, with jacoco activated.

Rsync the war file onto the test server

Restart web tomcat to load the new war file

Send a reset JMX command

run the regression test

Send a dump JMX command

rsync the jacoco-client output file back to the build server.

Run sonar-runner to analyze results

Hi,

As your log indicates, you're not getting your JaCoCo data included in the analysis because you're not providing the .class files to the analysis:

No JaCoCo analysis of project coverage can be done since there is no class files.

Use sonar.java.binaries to point to their location.
