在我的Java Gradle项目中运行JUnit测试时出现Assertion Error。Junit AssertionError
在该试验中我测试下面的方法：
@Override
public Projectile shoot(Point initialPosition, int angle, Player player)
{
if (!onCoolDown)
{
if (Config.soundfx)
{
sound = Gdx.audio.newSound(Gdx.files.internal("soundEffects/shoot.mp3"));
Random r = new Random();
double randomValue = 1.2 + (1.4 - 1.2) * r.nextDouble();
sound.setPitch(sound.play(1.0f), (float)randomValue);
//sound.play(1.0f);
}
shotsRemaining--;
onCoolDown = true;
cooldownTimer.schedule(new TimerTask() {
@Override
public void run()
{
onCoolDown = false;
}
}, cooldown);
Point aimPoint = new Point();
aimPoint.x = initialPosition.x + (int) (Math.sin(Math.toRadians(angle)) * 30);
aimPoint.y = initialPosition.y + (int) (Math.cos(Math.toRadians(angle)) * 30);
return new Projectile(angle, 10, ammunition, player, aimPoint, 0);
}
return null;
}
，这是JUnitTest：
@Test
public void testShoot_posY_posX_posAngle() {
System.out.println("shoot");
Point initialPosition = new Point(10, 10);
int angle = 10;
Player player = new Player("testPlayer", "");
HandGun instance = new HandGun("testHandGun", 0, new CircleCharacter("testCharacter", 0, 0, initialPosition));
Projectile expResult = new Projectile(angle, 10, instance.getAmmunition(), player, initialPosition, 0);
Projectile result = instance.shoot(initialPosition, angle, player);
assertEquals("projectile: " + result.toString() + " does not equal expected projectile: " + expResult.toString(), expResult, result);
}
，这是错误：
java.lang.AssertionError: projectile: does not equal expected projectile: expected:<[email protected]> but was:<[email protected]>

整个除assertEquals之外的测试工作。 只要它尝试执行assertEquals，它就会抛出异常。
