接触 Macaca 也蛮久了，中间断断续续折腾了一阵，自动化框架还在用老牌的 Appium，迁移是大事不能一蹴而就。最近有个机会准备分享一些 Macaca 的经验，我有开始来倒腾了。
使用 Macaca 做多终端的自动化对 Macaca 本身来说是支持的，可参考 xdf 分享的众多帖子，如：原来程序员都是这么聊天的，Macaca 如何实现多任务
接下来开始实验，PC 端多 electron 顺利完成。
接下来实验 Android，使用 TestNG 多线程方式运行 Suite 同时测试两个终端（代码在官方 macaca-test-sample-java 基础上修改）。
TestNG Suite

driver

}
@AfterClass
public void tearDown(MacacaClient driver) throws Exception {
driver.quit();
}
}
运行出现报错，错误信息如下：

看到这个报错后跟 xdf 咨询问题原因，也跟 harsayer (小马) 讨论了一下，均有此现象，很着急啊有木有。还提了个issue到 github。
折腾了挺久没有找到解决方法，不断尝试，在晚上与君禾沟通过程中尝试在线程中加了一个等待。右键运行 TestNg Suite，神奇的事情发生了，两个服务端均正常初始化 driver，设备上正常执行测试脚本，是不是我的诚心感动了天地。
修改后的代码（只在初始化 driver 前加了一句等待，个人怀疑是不是由于底层 instrumentation 不支持同时访问导致，具体原因不明）：
@Parameters({"port","udid"})
@BeforeClass
public void setUp(String port, String udid) throws Exception {
// platform: android or ios
String platform = "android";
JSONObject porps = new JSONObject();
porps.put("platformName", platform);
porps.put("app", System.getProperty("user.dir")+"/app/" + platform + "-app-bootstrap.zip");
porps.put("udid", udid);
porps.put("reuse", 1);
JSONObject desiredCapabilities = new JSONObject();
desiredCapabilities.put("host", "127.0.0.1"); // custom server host
desiredCapabilities.put("port", Integer.parseInt(port)); // custom server port
desiredCapabilities.put("desiredCapabilities", porps);
if(port.equals("4726"))
{
Thread.sleep(1000);
}
driver = driver.initDriver(desiredCapabilities);
System.out.println(driver);
}
运行效果：
