Appium自动化:出现错误-org.openqa.selenium.WebDriverException:无法解析远程响应:参数不正确

问题描述：

我正在尝试使用Java进行appium android自动化.下面是代码:

I am trying to do appium android automation using Java. Below is the code:

public class Main {

AppiumDriver driver;

@Before
public void setup() throws Exception{
    DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
    desiredCapabilities.setCapability("platformVersion","4.4");
    desiredCapabilities.setCapability("platformName","Android");
    desiredCapabilities.setCapability("app","/PATH_TO_APK");
    driver = new AndroidDriver(new URL("http://0.0.0.0:4723/wd/hub"),desiredCapabilities);
}

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

@Test
public void firstTest(){
    WebElement element = driver.findElementById("ELEMENT_ID");
    element.click();
}
}

下面是错误

org.openqa.selenium.WebDriverException: Unable to parse remote response: Parameters were incorrect. We wanted {"required":["desiredCapabilities"],"optional":["requiredCapabilities","sessionId","id","sessionId","id","sessionId","id","sessionId","id","sessionId","id","sessionId","id"]} and you sent ["desiredCapabilities","requiredCapabilities","capabilities"]
Build info: version: '3.4.0', revision: 'unknown', time: 'unknown'
System info: host: 'WGB01ML106163.local', ip: 'fe80:0:0:0:3e15:c2ff:febe:8ea0%en0', os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '10.11.6', java.version: '1.8.0_131'
Driver info: driver.version: AndroidDriver

有人以前见过此错误吗?无法在Google上找到任何东西.请帮忙.

Has anyone seen this error before? Cant find anything on Google. Please help.

答

我们还需要在功能中传递"deviceName".

We also need to pass the "deviceName" in the capabilities.

 desiredCapabilities.setCapability("deviceName","Android");

此外，如果您在移动设备中进行混合/本地应用程序测试，我们还需要传递appPackage和appActivity.因此，结合所有强制性功能后，总体所需功能将与此类似.

Also, if you doing hybrid/native app testing in the mobile, we need to pass appPackage and appActivity also. So combining all the mandatory capabilities, overall desired capabilities will look similar to this.

public void setup() throws Exception
{
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("deviceName","ANDROID");
capabilities.setCapability("platformVersion", "5.1");
capabilities.setCapability("platformName",Constant.appPlatform);
capabilities.setCapability("app", app.getAbsolutePath());
capabilities.setCapability("appPackage", Constant.appPackage);
capabilities.setCapability("appActivity",Constant.appActivity);

driver = new AndroidDriver(new URL("http://127.0.0.1:4727/wd/hub"),capabilities);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
}

获取appActivity/appPackage的简便方法是与开发人员联系.如果不可能，请检查此=>

Easy way to get appActivity/appPackage is contacting your developer. If not possible check this=>appActivity/appPackage

此处提供了有关各种功能的更多详细信息.
