[richa]

Hi there!!

i've made two clsses one with SwtTest and other is SwtTestTest..
however, when i try to run this prg as Junit test, i dont get any error n i've to forcibly terminate the error.
n yes one time it gave me an error at ArrestionError at getinstrumented
please check the code n do let me know wht the prob is.. where i'm wrong..

the code is as follows..
for class SwtTest

not the test class n tht is SwtTestTest

thanx:)

Have you run this on a command line?
If you are on windows, when it hangs, press Ctrl+Break and you will get a dump of all running threads.  It should be obvious which thread is stuck, then you need to work out why it is stuck and how to fix it.

thanx Barrie for the suggestion.. but i;m running the prg in eclipse as JUnit test.
n ctrl+Break is not working for me. n my prg do give an error but takes a long time .. like after an hour or so...

However, i've a doubt, i'm getting a null pointer exception at the line..
Text ttext1 = (Text)(finder.find(shell, new ClassMatcher(Text.class)));
assertSame(super.findText1(), ttext1);
n i'm not able to make out y..
now finder is the reference variable WidgetFinder class..

and what is the link between CCT and CCfindingTest??? like how and where is actually CCT calling CCFT??

last question.. can you tell me if there is any link for abbot.swt api..

thanx a lot
regards richa
