Grails 2.0 integration test pollution?

Question

So i have a small integration test that houses 5 tests in total. Running that test exclusively results in all tests passed. However running my entire test suite results in 4

Answer 1

My solution as to upgrade all the unit tests to grails 2.0 method of doing tests. When this was done, every test passed. So it seem's that unit tests somehow polluted integration tests. But only on certain hardware configurations.

Answer 2

I had a similar problem when moving from 1.3.7 to 2.0. The integration tests were ok when launched with

grails test-app --integration

but were failing when launched with

grails test-app

I fixed everything by converting unit tests to grails 2.0 test (using annotations).
