java - Appium 测试中的 SessionNotCreatedException 错误

Question

我正在尝试在 Eclipse 中运行以下测试:

public class AppiumTestOne {

private static AndroidDriver driver;

@Test
public void appiumTest() throws MalformedURLException, InterruptedException{

    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
    capabilities.setCapability("deviceName", "My Android");
    capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME,"Android");
    capabilities.setCapability("appPackage", "io.selendroid.testapp");
    capabilities.setCapability("appActivity", ".HomeScreenActivity");
    driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
    driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
    driver.findElement(By.xpath("//android.widget.EditText[@content-desc='my_text_fieldCD']")).sendKeys("Hello World");

    Thread.sleep(5000);

    driver.findElement(By.id("io.selendroid.testapp:id/startUserRegistration")).click();

    Thread.sleep(10000);
    driver.quit();

}

}

我在运行测试之前启动了 Appium 服务器，但是总是显示此错误:

 org.openqa.selenium.SessionNotCreatedException: A new session could not be        created. (Original error: 'java -version' failed. Error: spawn ENOENT) (WARNING: The server did not provide any stacktrace information)

有一个错误，特别是这行代码:

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

但是在appium服务器中，它说地址是127.0.0.1，端口是4723。

希望你能帮我解决这个问题。谢谢。

Answer 1

org.openqa.selenium.SessionNotCreatedException: A new session could not be created. (Original error: Requested a new session but one was in progress) 的重复项

如果不起作用，请尝试这个，

从 Windows 任务管理器终止 node.exe 进程。然后重新启动 Appium Server 并启动/运行它。
