By default, all tests are runned in the same jvm instance, that's why your static assignments are not reset.
You have 2 solutions : - clean up the static state between each test - use forkMode = always. It will create a new jvm for each test. However, as you can understand, it will perform much slower Vincent 2010/11/20 Kristian Rosenvold <[email protected]> > It sounds *very* much to me like the static state is not being reset > properly; you're not running in parallel unless you're using some exotic > custom stuff. > > Did you try to run multiple tests at once from eclipse ? > > Kristian > > > lø., 20.11.2010 kl. 21.17 +0100, skrev Iron Eagle: > > Hi, > > > > thank you, for your awnser. > > > > I have no explicit configuration of the surefire plugin in my pom file.
