I used grails 1.1beta1 and copied the code from the testing plugin document page(http://www.grails.org/Testing+Plugin) into a new application.
If I add the following assert in testCreateSomething()
assertEquals 1, testService.countItems("Bangle")
this function can pass the test. But the second function, testCountItems(), failed.
Without the assert, both tests are OK. It seems the new assert in the first function influenced the result of the second function.
Please refer to Line 28 of MyServiceTests.groovy. It seems this line cause the failure of testCountItems().
