How do I get Code Coverage analysis? [message #112184] Mon, 10 September 2007 18:34 Go to next message

I'm using Eclipse 3.3, TPTP 4.3 (although some features report 4.4) and
am using Java 1.5. I can't seem to generate any Code Coverage analysis
from running my plugin tests.

My setup: My test project is fragment that runs inside of the context of
the main plugin. The tests are run as JUnit Plugin tests.

When I profile the tests I get execution analysis data and can browse
where the time was spent, but the code coverage window says:

No execution statistics is available for display.
Either you have no trace selected in the Profiling Monitor view or
the current selection does not contain execution statistic information.

Note:
This view is available only if the trace contains execution
statistics. To collect this type of information, on the Profile tab in
the Launch configuration, choose the Execution Time Analysis option.

But this exactly what I set in the profiling window. So I ask How do I
get Code Coverage of my plugin tests using Java 1.5?

Cheers

Mark,
For Java 1.5+, JVMPI has been replaced with JVMTI, which does
not support method level code coverage. In TPTP and Java 1.4 or less, you
can use the Method Level code coverage
function. Method Level code coverage is another analysis type for the Java
Profiler data
collector in the Profiling launch configuration. For more information, see:

http://help.eclipse.org/help33/index.jsp?topic=/org.eclipse. tptp.platform.doc.user/tasks/tevwcode.htm

If you are interested in using the TPTP Method Level code coverage with
TPTP JUnit/Plug-in tests, please see the work-around here:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=138736#c17

TPTP does provide a line level code coverage tool as a Technology
Preview. However, this tooling is depredated (in place of EMMA integration)
and cannot be used with test execution. You can
learn about the TPTP Line Level Code Coverage tool (including a viewlet) for
the latest release at:

http://www.eclipse.org/tptp/home/downloads/downloads.php >> Deprecated
Technology
Previews >> Code Coverage

Moving forward, we are working at integrating EMMA for line level code
coverage with test execution in TPTP (see defect
https://bugs.eclipse.org/bugs/show_bug.cgi?id=170800). Please feel free to
comment or contribute to this defect.
