我正在尝试使用testNG创建一个appium测试框架。
我决定我想做一个非常简单的测试，只是在深入研究添加表和页面对象之前检查一切是否正常。
我运行了testNG测试并得到了
remote.ProtocolHandshake createSession
我不知道这是什么或如何解决。
所以我的问题很简单：
这是我的pom.xml依赖项

<version>5.0.4</version>
</dependency>
根据Java客户端文档，此版本支持selenium 3.6.0。因此，可以将selenium-java的版本更改为相同的版本，或者将java-client升级为较新的版本。如果您仍然遇到此问题，请进行更新。
答案 1 :(得分：0)
在您的所有帮助，一些头痛和大量研究下，我得以找到了这个问题的根本原因！
基本上，我 最初 构建了所需的功能，例如：
public class TestDragnDrop {
static AndroidDriver<AndroidElement> driver;
@BeforeTest
public void DesiredCapabilities() throws MalformedURLException{
DesiredCapabilities caps =new DesiredCapabilities();
caps.setCapability("deviceName", "JacquelineNexus5");
caps.setCapability("platformName", "Android");
caps.setCapability("platformVersion", "8.0");
caps.setCapability("appPackage", "com.example.android.apis");
caps.setCapability("appActivity", "ApiDemos");
AndroidDriver<AndroidElement> driver = new AndroidDriver<AndroidElement>(new URL("http://127.0.0.1:4723/wd/hub"),caps);
}
我应该做的事情和正确的方法是为Maven / TestNG自动化框架测试构建所需的功能，如下所示：
public class DragnDropTest {
static AndroidDriver<MobileElement> driver;
@BeforeTest
public AndroidDriver<MobileElement> initDriver() throws MalformedURLException{
DesiredCapabilities caps =new DesiredCapabilities();
caps.setCapability("deviceName", "JacquelineNexus5");
caps.setCapability("platformName", "Android");
caps.setCapability("platformVersion", "8.0");
caps.setCapability("automationName", "UiAutomator2");
caps.setCapability("appPackage", "com.example.android.apis");
caps.setCapability("appActivity", "ApiDemos");
driver = new AndroidDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), caps);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
return driver;
}
@Test
//Scenario: Perform Drag n drop function
您可以正常创建测试方案。
您可以正常查找元素并运行测试。
希望以后对其他人有帮助。
