Quality Assurance: testing•Junit•Integration Testing•User Acceptance Testing

Unit Test casepublic void testRemoveFriend() { GoogleTalkUserData e1 = new GoogleTalkUserData("Horton", "tim", "away"); GoogleTalkUserData e2 = new GoogleTalkUserData("Star", "Bucks", "Busy"); ad2.addFriend(e1); ad2.addFriend(e2); assertTrue(ad2.removeFriend(e2)); assertTrue(ad2.removeFriend(new GoogleTalkUserData( "Horton", "tim", "away")));

}

• There was a failure with this unit test, because the actual method was not dealing very well with objects.

Integration test• public void checkFriendAddition() throws Exception {

• // Ensure that adding a friend makes changes to both the

• // model and the database.

• FriendTempData foundFriend = null;

• controller.removeFriend(friendUserID);

• assertNull(model.findUserByAccountName(friendUserID));

• db = new DatabaseFunctions();

• for (FriendTempData f : db.getFriendListByAccountName(userID)) {

• assertTrue(!f.getUserID().equalsIgnoreCase(friendUserID));

• }

• controller.addFriend(friendUserID);

• assertNotNull(model.findUserByAccountName(friendUserID));

• db = new DatabaseFunctions();

• for (FriendTempData f : db.getFriendListByAccountName(userID)) {

• if (f.getUserID().equalsIgnoreCase(friendUserID)) {

• foundFriend = f;

• break;

• }

• }

• assertTrue(foundFriend.getUserID().equalsIgnoreCase(friendUserID));

• return;

• }

User Acceptance Testing• 1. We asked 10 users to try and run our software. • 2. We asked them to do the following tasks while one of the team

is loggin with cmpt275testing@gmail.com • a) Register with your GoogleTalk account • b) Add cmpt275testing@gmail.com • c) Send cmpt275testing a message • d) Wait for a message coming for cmpt275testing • e) (cmpt275 will sign out) send a message to chatbot and ask him

"What is your name?" and "What is up!" and wait for his respond • f) block cmpt275testing (cmpt275testing will sign again and he

should not find user) • g) delete cmpt275 testing • h) log out
