我想用Junit测试我用slick2d写的游戏（它是建立在LWJGL上的）。（也许做单元测试是个坏主意，但我选择了它作为我的家庭作业。）我在单独的线程中运行游戏，模拟鼠标点击，并做Assert测试。它运行良好，直到我有一个以上的测试功能。（我将“test”函数复制并粘贴到第二个函数）在第二个测试函数中创建另一个gameContainer和实际游戏会导致我的测试崩溃。我想我需要在测试后以某种方式重置游戏上下文，但我不知道如何。
以下是我的测试：（我尽量简化了）

@Test
public void test() throws InterruptedException {

    Thread t = new Thread(new engineTest());
    t.start();

    Thread.sleep(3000); // wait for game to initialize

    // Game simulation and asserts are here

    t.interrupt();

    Thread.sleep(1000);
}

我尝试了许多变化，包括调用.exit（）和.destroy（）到游戏容器，但它再次崩溃。
thread函数在这里：

public class engineTest implements Runnable {

  @Override
  public void run() {
      SapiensSlick.main(null); // SapiensSlick is name of the game 
  }
}

当第二个函数正在执行时，我得到这个错误：

[xcb] Unknown request in queue while dequeuing

[xcb] Aborting, sorry about that.
