any way to guarantee test environment is clean before starting next test?

[brucespringfield]

using Arquillian to run Integration Tests on JBoss, but it seems that memory is not being released from the previous test before the next test starts. We are seeing very periodic test results. Tests will fail on one build, Next test run will be all successful. Tests will fail on the following run, but a different set of tests than the failures on the first run. The next test run will be all successful. The following build will have tests fail, but again another set of tests than previously will fail.

I cannot really get the full picture from this description. Can you answer following, so I can understand better:

• Are the tests failing randomly within one build?
• What kind of container are you using? Is it remote JBoss or do you start it for each and every build?
• How do you know that memory is not released?
• Are your tests executed against stateful components?
