If I recall, we initially generated the coverage report manually by using below set of steps. Then the ServerUtils is used to handle that.
1. Create a jarlist.txt eg:* find /home/thilini/Desktop/wso2greg-3.6.0/repository/components/plugins/ >> /home/thilini/Desktop/wso2greg-3.6.0/repository/components/plugins/jarlist.txt * (jarlist.txt should contain absolute paths of jars. Remove unwanted jars from the list. If not there will be issues when starting the server) 2. xargs -n 1 $JAVA_HOME/jre/bin/java -cp emma.jar emma instr -m overwrite -cp < jarlist.txt 3. ruby dynamicImportsPatcher.rb < jarlist.txt (Before running this step need to install rubyzip. Use sudo apt-get install libzip-ruby1.8) 4. Copy emma.jar to */repository/components/plugins, /repository/components/lib *and */lib *directories. 4. Start Carbon Server 5. Do the test 6. Shutdown server 7. cp wso2greg-3.6.0/coverage.ec . 8. java -cp emma.jar emma report -r html -in coverage.em,coverage.ec <http://coverage.ec/>Thanks Thilini On Tue, Mar 20, 2012 at 8:02 AM, Afkham Azeez <az...@wso2.com> wrote: > Emma has been disabled for the past few months, and inevitably, the code > that does the instrumentation does not work.
