### Question:
TeamService { public List<Team> listTeamsJoined(long userId, String cluster, String path) { return teamBiz.listTeamsByPathAndUser(userId, cluster, path, true); }  @Transactional boolean create(long userId, String teamName, String cluster, String path); UserTeam addApply(long userId, long teamId, Role role); @Transactional void addApply(User user, long teamId, Role role); @Transactional void addMember(User member, long teamId, Role role, User creator); List<UserTeam> listUserTeamsPending(Team team); List<UserTeam> listUserTeamsAgree(Team team); List<UserTeam> listUserTeamsJoined(User user); List<Team> listTeamsToJoin(long userId, String cluster, String path); List<Team> listTeamsJoined(long userId, String cluster, String path); Team get(String teamName); Team get(long teamId); int updateStatus(long id, Status status); int agreeJoin(User user, long id, long teamId); int refuseJoin(User user, long id, long teamId); int updateRole(long id, Role role); boolean hasApplied(long teamId, String cluster, String path); boolean isMaster(long userId, long teamId); boolean isOwner(long userId, long teamId); boolean isAdmin(long userId);  }### Answer:
@Test public void testListTeamsJoined() throws Exception { long userId = 3; String cluster = "local_test"; String path = "/test/sub1"; List<Team> teams = teamService.listTeamsJoined(userId, cluster, path); Assert.assertNotNull(teams); Assert.assertEquals(1, teams.size()); }
