Below is the selendroid java code -
下面是 selendroid java 代码 -
package com.selendroid.demo;
import org.openqa.selenium.WebDriver;
import io.selendroid.SelendroidDriver;
import io.selendroid.common.SelendroidCapabilities;
import io.selendroid.common.device.DeviceTargetPlatform;
import io.selendroid.standalone.SelendroidConfiguration;
import io.selendroid.standalone.SelendroidLauncher;
public class Sele {
private WebDriver driver;
public void setUp() throws Exception {
System.out.println("------------------------Started");
SelendroidConfiguration config = new SelendroidConfiguration();
// Add the selendroid-test-app to the standalone server
config.addSupportedApp("Demo.apk");
// start the standalone server
SelendroidLauncher selendroidServer = new SelendroidLauncher(config);
selendroidServer.launchSelendroid();
// Create the selendroid capabilities
SelendroidCapabilities capa = new SelendroidCapabilities(
"io.selendroid.androiddriver:0.16.0");
capa.setAut("com.example.demo:1.0");
capa.setPlatformVersion(DeviceTargetPlatform.ANDROID15);
// capa.setEmulator(false);
// capa.setCapability(SelendroidCapabilities.EMULATOR, true);
// capa.setSerial("emulator-5554");
SelendroidDriver driver = new SelendroidDriver(capa);
capa.wait(100);
driver = new SelendroidDriver(capa);
}
}
Not familiar with testng and selendroid so please give the solution in detail.
对testng和selendroid不熟悉所以请详细给出解决方案。

It seems you don't have the testng jar in your classpath. Just add it.
您的类路径中似乎没有 testng jar。只需添加它。

I had the same problem and I found that the root cause was that in the POM file the scoop was "compile" to the Dependency of TestNG. All I had to do was erase the scoop setting for the TestNG dependency.
我遇到了同样的问题，我发现根本原因是在 POM 文件中，勺子被“编译”到了 TestNG 的依赖关系。我所要做的就是清除 TestNG 依赖项的 scoop 设置。
It is cause to the exception from the Eclipse TestNG plugin because the plugin do not has the TestNG jar in the classpath when it is running (it's running after the compilation phase)
这是 Eclipse TestNG 插件异常的原因，因为该插件在运行时的类路径中没有 TestNG jar（它在编译阶段之后运行）
Before:
前：
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.11</version>

After:
后：
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.11</version>
</dependency>

My testng jar was on classpath and testng plugin was also installed for eclipse. Converting my project to Maven project in eclipse solved the issue.
我的 testng jar 在类路径上，并且还为 Eclipse 安装了 testng 插件。在 Eclipse 中将我的项目转换为 Maven 项目解决了这个问题。
