[ http://issues.apache.org/jira/browse/LUCENE-721?page=comments#action_12457084 ] Grant Ingersoll commented on LUCENE-721: ----------------------------------------
OK, I committed this, with a minor change so that it is off by default (thanks Erik, for the ANT info). To run, you need three things: 1. clover.jar in ANT lib 2. clover.license in ANT lib 3. On the command line or in the your ANT properties, if you want it on all the time, you must specify -Drun.clover=true Thanks, Micheal. I will incorporate this into the nightly build per http://issues.apache.org/jira/browse/LUCENE-708 > Code coverage reports > --------------------- > > Key: LUCENE-721 > URL: http://issues.apache.org/jira/browse/LUCENE-721 > Project: Lucene - Java > Issue Type: New Feature > Components: Other > Reporter: Michael Busch > Assigned To: Grant Ingersoll > Priority: Minor > Attachments: clover.patch, code_coverage.patch, emma_report.zip > > > Hi all, > We should be able to measure the code coverage of our unit testcases.

It would be nice if we could add a page to the Lucene website > showing the report, generated by the nightly build. Maybe you could add that > to your preview page (LUCENE-707), Grant? > I attach a patch here that uses the tool EMMA to generate the code coverage > reports. EMMA is a very nice open-source tool released under the CPL (same > license as junit). The patch adds three targets to common-build.xml: > - emma-check: verifys if both emma.jar and emma_ant.jar are in the ant > classpath > - emma-instrument: instruments the compiled code > - generate-emma-report: generates an html code coverage report > The following steps are neccessary in order to generate a code coverage > report: > - add emma.jar and emma_ant.jar to your ant classpath (download emma from > http://emma.sourceforge.net/) > - execute ant target 'emma-instrument' (depends on compile-test, so it will > compile all core and test classes) > - execute ant target 'test' to run the unit tests > - execute ant target 'generate-emma-report' > To view the emma report open build/test/emma/index.html -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
