Question

我正在使用Java和Selenium通过命令行初始化Appium，以便在Android Chrome浏览器上运行测试。但是，该过程运行无限时间，并且来自＆＃34; DesiredCapabilities＆＃34;行没有被执行.. 代码：

Process proc;
String path_to_appium = System.getenv("APPIUM_HOME") + File.separator + "node_modules" + File.separator + "appium" + File.separator + "bin" + File.separator + "appium.js";
String path_to_node = System.getenv("APPIUM_HOME") + File.separator + "node.exe";
proc = Runtime.getRuntime().exec("\"" + path_to_node + "\"" + " " + "\"" + path_to_appium + "\"" + " " + "--address 127.0.0.1 --browser-name Chrome --platform-name Android --platform-version 17 --automation-name Appium --chromedriver-port 9516 --bootstrap-port 4724 --no-reset --local-timezone --log appium_log.log");

System.out.println("Android Chrome driver would be used");

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName","Android");
capabilities.setCapability("deviceName", "HTC One X");
capabilities.setCapability("platformVersion", "4.2.2");
capabilities.setCapability("device", "android");
capabilities.setCapability("browserName", MobileBrowserType.CHROME);

Thread.sleep(2000);
driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.get("test.com");

我无法在控制台中获得任何输出。

什么都没发生。该过程不会进行下一行（即设置DesiredCapabilities）。镀铬无法在设备上启动。

注意：当我从命令行执行命令，然后从DesiredCapabilities行开始测试时，测试运行正常并且chrome已成功初始化。

代码有什么问题？

Answer 1

问题在于最新的appium版本，即1_4_16_1。

当以编程方式启动appium服务器时，它正在创建一个死锁，因为驱动程序没有被初始化。

使用Appium的ServerArguments并替换行

后问题得以解决

proc = Runtime.getRuntime().exec("\"" + path_to_node + "\"" + " " + "\"" + path_to_appium + "\"" + " " + "--address 127.0.0.1 --browser-name Chrome --platform-name Android --platform-version 17 --automation-name Appium --chromedriver-port 9516 --bootstrap-port 4724 --no-reset --local-timezone --log appium_log.log");

以下代码：

            ServerArguments serverArguments = new ServerArguments();
            serverArguments.setArgument("--address","127.0.0.1");
            serverArguments.setArgument("--chromedriver-port", 9516);
            serverArguments.setArgument("--bootstrap-port", 4724);
            serverArguments.setArgument("--browser-name", "Chrome");
            serverArguments.setArgument("--no-reset", true);
            serverArguments.setArgument("--local-timezone", true);
            AppiumServer appiumServer = new AppiumServer(appium_folder, serverArguments);
            appiumServer.startServer();
driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.get("test.com");

我认为问题在于你在proc输出中循环，你永远不会离开那里，看你甚至没有得到＆＃34;这是命令的标准错误（如果任何）：\ n＆＃34;

我将输出日志记录放在另一个线程上以便您的程序可以继续运行，以下代码可以改进但是应该完成工作：

Process proc;
String path_to_appium = System.getenv("APPIUM_HOME") + File.separator + "node_modules" + File.separator + "appium" + File.separator + "bin" + File.separator + "appium.js";
String path_to_node = System.getenv("APPIUM_HOME") + File.separator + "node.exe";
proc = Runtime.getRuntime().exec("\"" + path_to_node + "\"" + " " + "\"" + path_to_appium + "\"" + " " + "--address 127.0.0.1 --browser-name Chrome --platform-name Android --platform-version 17 --automation-name Appium --chromedriver-port 9516 --bootstrap-port 4724 --no-reset --local-timezone --log appium_log.log");

BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));

new Thread()
{
    public void run() {
        // read thae output from the command
        System.out.println("Here is the standard output of the command:\n");
        String s = null;
        while ((s = stdInput.readLine()) != null) {
            System.out.println(s);
        }

        // read any errors from the attempted command
        System.out.println("Here is the standard error of the command (if any):\n");
        while ((s = stdError.readLine()) != null) {
            System.out.println(s);
        }
    }
}.start();

System.out.println("Android Chrome driver would be used");

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName","Android");
capabilities.setCapability("deviceName", "HTC One X");
capabilities.setCapability("platformVersion", "4.2.2");
capabilities.setCapability("device", "android");
capabilities.setCapability("browserName", MobileBrowserType.CHROME);

Thread.sleep(2000);
driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
driver.get("test.com");

以编程方式启动时，Appium不会初始化驱动程序
