libgdx-单元测试-如何与应用程序线程通信? [英] libgdx - junit testing - how do I communicate with the Application thread?

问题描述

我正在尝试在libgdx游戏上进行junit测试，并且发现此线程非常有用:

I am trying to do junit testing on a libgdx game, and have found this thread to be very helpful: Unit-testing of libgdx-using classes

我有一个类似于以下内容的测试类:

I have a test class similar to the following:

public class BoardTest {

    private static Chess game;
    private static HeadlessApplication app;

    @BeforeClass 
    public static void testStartGame() {

        game = new Chess();

        final HeadlessApplicationConfiguration config = new HeadlessApplicationConfiguration();
        config.renderInterval = 1f/60; // Likely want 1f/60 for 60 fps
        app = new HeadlessApplication(game, config);

    }

    @Test
    public void testSetUpBoard() {

        final boolean isFalse = false;

        Gdx.app.postRunnable(new Runnable() {
            @Override
            public void run() {

                //do stuff to game
                fail(); //see if the test will fail or not

            }
        });
    }
}

当我运行此测试类时，它将运行testSetUpBoard()并通过，而不是像应该的那样失败.我相信，这样做的原因是，根据Gdx.app.postRunnable()，执行的代码位于单独的线程中.有什么方法可以与junit线程通信，以便完成上述测试?

When I run this test class, it runs testSetUpBoard() and passes, instead of failing like it should. The reason for this, I believe, is because the executed code is in a separate thread as per Gdx.app.postRunnable(). Is there any way that I can communicate back to the junit thread, so that I can complete my tests like described?

推荐答案

您可以等待线程完成，如下所示:

You can wait for the thread to finish like this:

private boolean waitForThread = true;

@Test
public void testSetUpBoard() {


    final boolean isFalse = false;

    Gdx.app.postRunnable(new Runnable() {
        @Override
        public void run() {
            //do stuff to game            
            waitForThread = false;
        }
    });

    while(waitForThread) {
        try {
            Thread.sleep(10);
        } catch(Exception e ) {
        }
    }

    // fail or pass...
    fail(); //see if the test will fail or not
}
