i do not think that i really solved the issue. nevertheless i coded
around it a bit and now i can run server side AND client side code
test cases without any problems. feel free to browse through the
honeycrm sourcecode to see how i did it:
http://code.google.com/p/honeycrm/source/browse/#svn/trunk/src/honeycrm/client/test
important to note is the following: since the service (communication
from client to server side) could not be constructed using
gwt.create() when the client side tests are running, i decided to
replace the service before running the tests: see
http://code.google.com/p/honeycrm/source/browse/trunk/src/honeycrm/client/test/AbstractClientTest.java
and http://code.google.com/p/honeycrm/source/browse/trunk/src/honeycrm/client/ServiceRegistry.java
the result is not really satisfying since i cannot run the ui code
test cases and use the correct service (that will be used in
production mode). however, i can at least test all the other stuff and
i can test the ui code with a dummy service if i want to. of course, i
still want to have a real solution (instead of this dirty workaround)
allowing me to test the client code properly. but since i found no
solution yet and the google guys did not help me out either i had to
go on with this workaround until some gwt guru comes and fixes my
issue.
by the way: i am looking for developers who are interested in
participating in the honeycrm project. we welcome everyone who wants
to contribute and give feedback to the project!
kind regards,
ingo
