Ok I managed to do it without copying akka internal classes.
I'm not sure what I was doing wrong but this seems to work:
enterBarrier("before-split")
runOn(first) {
// split the cluster in two parts (first, second) / (third, fourth, fifth)
for (role1 ← side1; role2 ← side2) {
testConductor.blackhole(role1, role2, Direction.Both).await
}
}
enterBarrier("after-split")
runOn(side1: _*) {
receiveN(side2.size).collect { case MemberRemoved(m, _) => m.address }.toSet
should be(
side2.map(node(_).address).toSet)
}
runOn(side2: _*) {
receiveN(side1.size).collect { case MemberRemoved(m, _) => m.address }.toSet
should be(
side1.map(node(_).address).toSet)
}
