> 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
