由于NullPointerException,此JUnit测试(和其他)总是失败。当我调试时,它返回错误" Source not found"在线sq.setPlayers(球员); 下面是使用的类方法及其依赖项的列表。我无法想象为什么它不起作用。
public class SingleEliminationTest {
private Queue queue;
private Match currentMatch;
private SingleElimination sq;
public void setUp() {
queue = new Queue(4);
sq = new SingleElimination();
}
@Test
public void setPlayers()
{
ArrayList<String> players = new ArrayList<String>();
players.add("Max Atkins");
players.add("Hannah Marlow");
players.add("Liam Ross");
players.add("Chandlar Bruce");
sq.setPlayers(players);
assertEquals("Not enough players", queue.length(), 4);
}
public class SingleElimination implements IManager
{
private Queue queue;
private Match current;
public SingleElimination()
{
queue = new Queue(5);
}
/**
* Set the players or teams to use in the competition
* @param players the players or teams
*/
public void setPlayers(ArrayList<String> players)
{
for(String player : players)
{
queue.enQ(player);
}
}
public class Queue
{
Object[] queue;
int head;
int tail;
int length;
public Queue(int startSize)
{
queue = new Object[startSize];
head = tail = length = 0;
}
// Adds an Object to the back of the queue.
public void enQ(Object o)
{
if(length == queue.length)
{
//queue = new Object[queue.length * 2];
}
queue[tail++] = o;
length++;
if(tail == queue.length)
{
tail = 0;
}
}

您需要注释setup
方法,否则无法运行。我对JUnit不是很熟悉,但我怀疑@BeforeClass
或@Before
会做你期望的事。
答案 1 :(得分:1)
如果您希望自己的设置方法在每次测试之前运行 (任何使用@Before
注释的方法),请使用@Test
注释,使用@BeforeClass
如果您希望您的设置方法只运行一次,则注释。
答案 2 :(得分:0)
您需要使用setUp
为@Before
方法添加注释。它没有被运行。
