java - 配置失败 : @AfterClass teardown error in appium

Question

我在 appium 中收到 CONFIGURATION: @AfterClass Teadown 和 FAILED: testCal 错误。如何解决此问题？我使用 TestNG 运行了测试。请参阅下面的详细信息:

package Appium;

import java.net.MalformedURLException;
import java.net.URL;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;
import org.openqa.selenium.remote.CapabilityType;

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.remote.MobileBrowserType;
import java.net.URL;

public class AppiumPOC {


        WebDriver driver;

        @BeforeClass
        public void Appium() throws MalformedURLException{

            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.setCapability("device", "Android");
            capabilities.setCapability(CapabilityType.BROWSER_NAME, "Chrome");
            capabilities.setCapability(CapabilityType.VERSION, "4.2.2");
            capabilities.setCapability("platformName", "Android");
            capabilities.setCapability("deviceName","4100a9102db72100");
            capabilities.setCapability(CapabilityType.PLATFORM, "WINDOWS");


            capabilities.setCapability("app", "chrome");
            WebDriver driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);



          }

        @Test
        public void testCal()
        {
            driver.get("http://google.com");

        }

        @AfterClass
        public void teardown(){
            //close the app
            driver.quit();
        }
    }

请在下面找到控制台消息。我使用 TestNg 运行方法进行了测试，并在不同的平台上进行了尝试，但仍然面临同样的问题。

Answer 1

好的。现在它在我这边起作用了。只需从这一行中删除“WebDriver”即可:

 driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
