Hi, We are using Drools 3.0.6 using a test-driven approach. This works really well in allowing us to get good test coverage around our rules and to create those rules rather easily. However, as the number of tests grows, the execution speed of the test suite in our Continous Integration environment is taking longer and longer (expected, I know). We've broken our rules out into separate .drl files and try to test them in isolation by instantiating a new WorkingMemory in the setup method of each test and then setting the WorkingMemory variable to null in the tearDown method. Is there a way to re-use the WorkingMemory object such that we don't have to create a new one, at the start of a test, and have it garbage-collected, at the end? How are others doing similar things? Our goal is to reduce the execution time of our testsuite. Thanks for any and all replies. John
