Anyone tried using emma (emma.sf.net) to look at test coverage for our
tests? That might help ensure we don't trim them down too much?
I suspect we will soon reach a point where there are significantly fewer
obvious opportunities for small contributions - e.g. 1.5 generification,
etc from looking at JAPI reports. Having test coverage reports might
help by highlighting areas for improvement.
I had a quick try with:
ant -f make/build.xml
ant -f modules/nio/make/build.xml test
java -cp emma.jar emma instr -m overwrite -cp deploy/jdk/jre/lib/boot/nio.jar
and then:
java -Xbootclasspath/p:emma.jar \
-cp build/tests:modules/nio/bin/test:junit.jar:. \
junit.textui.TestRunner \
org.apache.harmony.tests.java.nio.channels.SocketChannelTest
(Running all the tests is a little tricky because test depends on build,
which depends on clean which wipes out the instr'd jar. ;-( )
Sadly it dies horribly with the stack trace below. I'll take another
look when I have a little more time, but I thought I'd mention it in
case anyone else had any thoughts on the subject.
Regards,
Mark.
