[ http://issues.apache.org/jira/browse/LUCENE-721?page=comments#action_12452544 ] Grant Ingersoll commented on LUCENE-721: ----------------------------------------
Care to update this for Clover, Michael? Then I can hook it into the site and the nightly builds. Thanks, Grant > 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 > Priority: Minor > Attachments: code_coverage.patch, emma_report.zip > > > Hi all, > We should be able to measure the code coverage of our unit testcases. I > believe it would be very helpful for the committers, if they could verify > before committing a patch if it does not reduce the coverage. > Furthermore people could take a look in the code coverage reports to figure > out where work needs to be done, i. e. where additional testcases are > neccessary. 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]
