org.openqa.selenium.WebDriverException:返回值无法通过Appium和iOS转换为W

Question

我面临的问题是：返回的值无法转换为WebElement。我使用BrowserStack作为云平台。

我的应用程序代码：

package root;
import java.net.MalformedURLException;
import java.net.URL;
import org.openqa.selenium.By;
import org.openqa.selenium.remote.DesiredCapabilities;
import io.appium.java_client.AppiumDriver;
import io.appium.java_client.ios.IOSDriver;
public class test123 {
public static void main(String[] args) throws MalformedURLException, InterruptedException
{
String userName="brenda467";
String accessKey="adfadfadfadf";
DesiredCapabilities caps = new DesiredCapabilities();      
caps.setCapability("browserstack.user", userName);
caps.setCapability("browserstack.key", accessKey);

caps.setCapability("platform","iOS");             
//caps.setCapability("platformName","iOS");           
caps.setCapability("deviceName","iPhone 7");       
caps.setCapability("os_version","10.3");    
caps.setCapability("app","bs://asfasdfasfasdfasfa");                    
caps.setCapability("browserstack.debug",true);
caps.setCapability("automationName","XCUITest");
//caps.setCapability(MobileCapabilityType.NEW_COMMAND_TIMEOUT, "60");
caps.setCapability("noReset", true);        

AppiumDriver driver = new IOSDriver(new URL("http://hub.browserstack.com/wd/hub/"), caps);
Thread.sleep(900);
driver.findElement(By.xpath("//XCUIElementTypeOther[@name='LOG IN']")).click();
}
}

控制台输出：

我的pom。xml:

<dependency>
<groupId>io.appium</groupId>
<artifactId>java-client</artifactId>
<version>7.0.0</version>
</dependency>
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.141.59</version>
</dependency>

注意：我已经尝试了许多在线解决方案。。以及下面的一个。https://discuss.appium.io/t/org-openqa-selenium-webdriverexception-returned-value-cannot-be-converted-to-webelement/18608

Answer 1

pom.xml包含Selenium v3.141.59依赖项，如下所示：

<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.141.59</version>
</dependency>

但根据日志消息：

Build info: version: '3.6.0', revision: '6fbf3ec767', time: '2017-09-27T15:28:36.4Z' System info: host: 'V00XYZ', ip: '100.00.00.100', os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_191' 
Driver info: driver.version: IOSDriver 

这有效地表明正在使用Selenium v3.6.0，因此您看到的错误为：

org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement

解决方案

• 通过IDE清理您的项目工作区，并仅使用所需的依赖项重建项目
• 执行您的@Test
