Java Stack Overflow Model Unit Tests

AAA pattern Unit Test

Hello, I'm trying to follow the AAA pattern in Unit Test, but I would like to know if it's ok to add some Act code in the @Before annotation. In order to keep my code DRY, I set the method alice.askQuestion, for example, inside the @Before annotation because it will be used repeatedly through the tests. I put an example of my code in order to know if this structure is ok? Should I add as comments when is Arrange, Act and Assert? Thanks.

@Before public void setUp() throws Exception {

    Board board = new Board("Java");
    alice = board.createUser("alice");
    bob = board.createUser("bob");
    charlie = board.createUser("charlie");
    question = alice.askQuestion("What is a String?");
    bobAnswer=bob.answerQuestion(question,"A sequence of characters");
    bobPost=bob.answerQuestion(question,"A sequence of characters");

}


@Test
public void reputationGoesUpIfQuestionUpvoted() throws Exception {

    bob.upVote(question);

    assertEquals("Reputation doesn't goes up by 5",5,alice.getReputation());
}

I think putting those in setUp() is fine as long as you are aware that it will get executed prior to each test method.
