Question

我想使用android模拟器自动测试移动应用程序。我试图以编程方式启动Appium，然后将其IP和端口传递给Webdriver，以供使用。

在我将它传递给Webdriver之前，我打印出它正在运行的Appium Service的IP /端口，它是0.0.0.0:4723，但是在将它传递给Webdriver后我得到一个连接被拒绝

如果我手动启动Appium，它将从0.0.0.0:4723开始，就好了。

请在下面找到我的代码和StackTrace。

public class AppiumServerJava {

public AppiumDriverLocalService service;
public AppiumServiceBuilder builder;
public DesiredCapabilities cap;
public WebDriver driver = null;
public DesiredCapabilities dc;

File root = new File(System.getProperty("user.dir"));
File app = new File(root, "/src/test/api/app-qa.apk");

public WebDriver startServer() {

    // apk Capabilities
    dc = new DesiredCapabilities();
    dc.setCapability("BROWSER_NAME", "Android");
    dc.setCapability(MobileCapabilityType.PLATFORM_NAME, Platform.ANDROID);
    dc.setCapability("deviceName", "nexus5");
    dc.setCapability("app", app.getAbsolutePath());
    dc.setCapability("appPackage", "com.aa.android.qa");
    dc.setCapability("appActivity", "com.aa.android.view.SplashActivity");

    // Appium Capabilities
    cap = new DesiredCapabilities();
    cap.setCapability("noReset", "false");

    // Build the Appium Service
    builder = new AppiumServiceBuilder();
    builder.usingDriverExecutable(new File("/home/ninad/.linuxbrew/bin/node"));
    builder.withAppiumJS(new File("/usr/local/bin/appium"));
    builder.withIPAddress("0.0.0.0");
    builder.usingPort(4723);
    builder.withCapabilities(cap);
    builder.withArgument(GeneralServerFlag.SESSION_OVERRIDE);
    builder.withArgument(GeneralServerFlag.LOG_LEVEL, "error");

    // Start the server with the builder
    try {
        service = AppiumDriverLocalService.buildService(builder);
        service.start();
        } catch (NullPointerException e) {
        e.printStackTrace();
        }

    String appiumServiceUrl = service.getUrl().toString();
    System.out.println("Appium URL " + appiumServiceUrl);

    try {
        driver = new AndroidDriver<>(new URL(appiumServiceUrl), dc);
        driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
    return driver;
}


public void stopServer() {
    service.stop();
}

public boolean checkIfServerIsRunnning(int port) {

    boolean isServerRunning = false;
    ServerSocket serverSocket;
    try {
        serverSocket = new ServerSocket(port);
        serverSocket.close();
    } catch (IOException e) {
        // If control comes here, then it means that the port is in use
        isServerRunning = true;
    } finally {
        serverSocket = null;
    }
    return isServerRunning;
}
}


AppiumServerJava appiumServer = new AppiumServerJava();
public static WebDriver driver = null;


@Before("@setup")
public void setUp() {

    int port = 4723;
    try {
        if (!appiumServer.checkIfServerIsRunnning(port)) {
            appiumServer.startServer();
            appiumServer.stopServer();
        } else {
            System.out.println("Appium Server already running on Port - " + port);
        }
    } catch (NullPointerException e) {
        e.printStackTrace();
    }

    driver = appiumServer.startServer();
}

Answer 1

我删除了端口详细信息并替换为usingAnyPort，下面是为我工作的示例junit测试

public class AppiumServerJava {

private AndroidDriver<MobileElement> driver;


@Before
public void startAppiumServer() {
    startServer();
}

@Test
public void serviceStartTest() {
    System.out.println(driver.findElements(By.xpath("//android.widget.TextView")).size());
}

@After
public void teardown() {
    driver.quit();
}

public void startServer() {


    AppiumServiceBuilder builder;
    DesiredCapabilities cap;
    DesiredCapabilities dc;

    File app = new File("/Users/test/Desktop/APK/staging.apk");
    // apk Capabilities
    dc = new DesiredCapabilities();
    dc.setCapability(MobileCapabilityType.PLATFORM_NAME, Platform.ANDROID);
    dc.setCapability("deviceName", "Android Emulator");
    dc.setCapability("app", app.getAbsolutePath());
    // Appium Capabilities
    cap = new DesiredCapabilities();
    cap.setCapability("noReset", "false");

    // Build the Appium Service
    builder = new AppiumServiceBuilder();
    builder.withAppiumJS(new File("/usr/local/bin/appium"));
    builder.withIPAddress("0.0.0.0");
    builder.usingAnyFreePort();
    builder.withCapabilities(cap);
    builder.withArgument(GeneralServerFlag.SESSION_OVERRIDE);
    builder.withArgument(GeneralServerFlag.LOG_LEVEL, "error");

    // Start the server with the builder
    AppiumDriverLocalService service = null;
    try {
        service = AppiumDriverLocalService.buildService(builder);
        service.start();
    } catch (NullPointerException e) {
        e.printStackTrace();
    }

    String appiumServiceUrl = service.getUrl().toString();
    System.out.println("Appium URL " + appiumServiceUrl);

    try {
        driver = new AndroidDriver<MobileElement>(new URL(appiumServiceUrl), dc);
        driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

}

Answer 2

通过以下信息启动您的appium服务器

主机：127.0.0.1 端口：4890

并在脚本中使用以下URL

URL url =新的URL（“ http://127.0.0.1:4890/wd/hub”）;

以编程方式启动Appium - 拒绝连接
