Jemmy V2 - question (test-automation, blackbox)

[Rev Kapuganti]

Thank you Shura, thats great details. Out of all the options you have
recommended, I believe the below option sounds feasible because of the
complexities and different custom parameters (configs )required for
launching this heavy loaded OR-POS application and also my test automation
framework of choice(Jruby based - runs on JVM).  Unfortunately a simple
java invocation of the main class with java_options and application params
wouldn't do it.


Preferred option -

If, for whatever reason, it is not possible to start the app from the
harness setup methods, you can try to modify the batch file of yours by
inserting your own class in front of the application main class which, the
way I imagine your script, you already have in the line where java binary
is called.


My question with this option is -  My test suite(cucumber) entry point is
a ruby-file( cucumber's env.rb : which creates an instance of Object class)
and it then calls all the tests under the suite directory. I'm also using a
bunch of JARs for doing a bunch of other things(to talk to databases, my
simulation servers, reporting apps and others). I would like to mix in
jemmy here for talking to the GUI of swing app.

 This cucumber suite(since its Jruby) is run on JVM through
command-line(for example:  Jruby -S cucumber -p test-profile).  Are you
recommending somehow adding this invocation along with the POS app's main
class while launching it through the batch file?
