Code coverage for GUI based functional tests

Question

I am trying to get bytecode coverage analysis using a code coverage tool (like Emma or Jacoco) after testing with a GUI based functional testing tool (like HP QuickTest Pro or Selenium).

Anyone who has done this could please give me an idea to start this project?

Answer 1

I am doing this now. My approach is to use JaCoCo ant tasks to instrument the binary byte-code files, and use a specific CLASSPATH to execute the instrumented binaries from an ant build.xml from Jenkins.

The reason for doing the code coverage from byte-code is that there is an existing set-up that runs test scripts for a large application using HP QuickTest Pro . I would imagine that the test coverage is in the single digits, but we need an empirical baseline to demonstrate the possible improvements in code coverage from doing unit tests during a build.
