我正在使用 Spring Boot 2 和 Appium 从头开始创建一个新的测试框架。为了编写测试，我使用了 JUnit，它已经包含在 Spring Boot 的 spring-boot-starter-test POM 中，还有很多其他的。我将 Appium 添加到我的 POM 中，它现在看起来像这样：

至于我的测试，我有一个如下所示的 DriverSetup class：
@RunWith(SpringRunner.class)
@SpringBootTest
public class DriverSetup {
protected AndroidDriver<AndroidElement> driver;
@Before
public void setUp() throws MalformedURLException {
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
capabilities.setCapability(MobileCapabilityType.PLATFORM_VERSION, "6.0.1");
capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "DeviceName");
capabilities.setCapability(AndroidMobileCapabilityType.APP_PACKAGE, "com.google.android.gm");
capabilities.setCapability(AndroidMobileCapabilityType.APP_ACTIVITY, ".ConversationListActivityGmail");
URL myUrl = new URL("http://127.0.0.1:4723/wd/hub");
this.driver = new AndroidDriver<AndroidElement>(myUrl, capabilities);
this.driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
}
}
最后，我还有另一个 class 从 DriverSetup 扩展而来，以确保在每次测试之前完成驱动程序初始化。它看起来像这样：
@RunWith(SpringRunner.class)
@SpringBootTest
public class FirstTryTest extends DriverSetup {
public FirstTryTest() { }
@Test
public void test() {
System.out.println("test");
}
}
我只是想确保我可以在 FirstTryTest 中进行测试，但每次代码使用 URL 和 DesiredCapabilities 初始化 AndroidDriver 时，我都会得到以下错误：

我试过使用旧版本的 Appium (5.0.4)，但没有成功。我想强调 StackTrace 的结尾。提到了 IOException 而在其他具有类似错误的问题中，脚本由于
org.openqa.selenium.json.JsonException`.
此错误信息：
java.lang.NoSuchMethodError: org.openqa.selenium.json.JsonOutput.write(Ljava/lang/Object;)Lorg/openqa/selenium/json/JsonOutput;
.
Suppressed: java.io.IOException: Incomplete document
...暗示 java.lang.NoSuchMethodError 是由 JVM.
引发的
您提到过使用旧版本的 Appium v5.0.4
如果没有以下与您的测试环境相关的信息，则很难分析错误：
- Appium 服务器版本
- 桌面OS/version
- 移动platform/version正在测试
- 真实设备或emulator/simulator
根据讨论 Error while running Appium script with AndroidDriver and iOS :Could not initialize the ios capabilities with 6.0.0 ，此错误似乎来自 NumberCoercer Class，已在 Selenium RemoteDriver 中修改v3.12.0 接受 Port 作为 Integer 而早些时候它接受 String.
解决方案
- 更新到最新的Appium Java客户端v6.1.0
- 更新到最新（至少）Selenium v3.12.0
@SrinivasanTarget 提到了一个重要方面：
Appium's Java client comes along with Selenium Dependency so we don't recommend to exclude selenium and add as separate dependency as it may raise conflicts at times.
