Currently, Test Suite is using surefire plugin to run integration tests. Failsafe is more suitable to do this, and the goal is to migrate from surefire to failsafe for IT.
However, there is a difference in how surefire and failsafe behaves when running a single test from CLI.
Surefire ignores <includes> pattern by default. This is optional (http://jira.codehaus.org/browse/SUREFIRE-806).
Failsafe does not ignore <includes> thus will not execute some tests that surefire would. Currently, this is not optional (http://jira.codehaus.org/browse/SUREFIRE-856).
It needs to be decided whether to ignore <includes> by default, in which case http://jira.codehaus.org/browse/SUREFIRE-856 needs to be resolved before migrating to failsafe (https://jira.jboss.org/browse/AS7-4065), or not.
