在携程使用 TestNG/JUnit 并行跑 Appium 有两个关键的地方：

• 独立使用的 Appium Server Wrapper
• 控制并行的 Device Store Queue

Word is Cheap,示例代码如下 (公布这些代码是希望大家更多的精力放到改进 Appium 本身)：

public abstract class AbstractDeviceStore<T extends Device> implements
        DeviceStore<T> {

    protected static final Logger log = LoggerFactory
            .getLogger(AbstractDeviceStore.class);

    protected final ReentrantLock lock;
    protected final Condition notEmpty;
    protected final TreeSet<Device> devicesInUse = new TreeSet<>();
    protected final Set<T> devices = new TreeSet<>();

    protected AbstractDeviceStore() {
        lock = new ReentrantLock(true);
        notEmpty = lock.newCondition();
    }

    @Override
    public Device take() throws InterruptedException {
        final ReentrantLock lock = this.lock;
        lock.lockInterruptibly();
        try {
            // log.debug("devices in use size {}", devicesInUse);
            while (devicesInUse.isEmpty()) {
                log.debug("take need wait ....");
                notEmpty.await();
            }
            return devicesInUse.pollFirst();

        } finally {
            lock.unlock();
        }
    }

    @Override
    public void put(Device device) {
        final ReentrantLock lock = this.lock;
        lock.lock();
        try {
            devicesInUse.add(device);
            notEmpty.signal();
        } finally {
            lock.unlock();
        }

    }

    @Override
    public Set<T> getDevices() {
        return new TreeSet<T>(devices);
    }

}
