Is the Eclipse Workbench already started at that time?
You need to make sure Eclipse UI and SWT are ready to work before
starting your test.

Its Better if you use the Junit Plugin Test to Run the Swtbot Tests.

Hi Pawan,

Thanks for the reply but there are some advance annotations provided in TestNG framework(like @Beforetest) those are not supported in Junit.
