[classlib] [testing] Coverage (was Re: 37% of total test execution time is spent in a single test)
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.

Yes please, upload the list into JIRA. I'm going to experiment with the list
and source coverage of HY API too.
When I tried to experiment with HY API by unit tests code coverage
measurement via Emma I saw such errors.
The reason why runtime dies is that Emma instruments core classes and
inserts calls to its classes, which, in their turn, depend on the being
initialized core classes (for example, initialization of java.lang.Object is
working, it calls instrumented code, i.e. Emma class to store profiling
information, but the class in its turn depends on Object).
Thanks,
Vladimir

Re: [classlib] [testing] Coverage (was Re: 37% of total test execution
time is spent in a single test)
Posted by Paulex Yang <pa...@gmail.com>.
Mark,
I'm glad that there is someone else has interest on emma, I've tried it
before. AFAIK, emma works by instrumentation, but sometimes for classes
in bootclasspath, the instrumentation cannot work, there are two cases:
1. Some instrumented classes cannot be loaded by VM.
2. Some classes cannot be instrumented
I have tried to look more inside to find some way to work around but I
haven't got enough time yet.
Specifically for nio-channel module, I had a list for these two cases (I
believe the data is a little outdated and should be reevaluated)
case 1.
BaseByteBuffer.class
Buffer.class
BufferFactory.class
ByteBuffer.class
CharArrayBuffer.class
CharBuffer.class
HeapByteBuffer.class
ReadWriteCharArrayBuffer.class
ReadWriteHeapByteBuffer.class
FileChannel.class
AbstractInterruptibleChannel.class
FileChannelImpl.class
WriteOnlyFileChannel.class
LockManager.class
LockManager$1.class
ReadOnlyFileChannel.class
case 2:
ByteChannel.class
Channel.class
GatheringByteChannel.class
InterruptibleChannel.class
WritableByteChannel.class
And I have got some ant script and more excluded list for emma, if
anyone has interests, I can upload it to JIRA.
