我想使用Java编程通过不同的端口运行appium的多个实例。
例如伪
for( 2 times){
int port = getRendomFreePort()
StartAppiumUsingPort(port)
driver = CreateAppiumDriver()
PerformTest()
CloseAppiumDriver()
CloseAppium()
}
使用实际代码执行上述步骤时，在appium启动之后，appium驱动程序出现错误。
我写的代码如下：
第一个示例：只需使用相同的端口打开两次并成功运行Java程序
for( 2 times){
int port = getSamePort() // Using Same port
StartAppiumUsingPort(port)
// node creating appium driver
CloseAppiumDriver()
CloseAppium()
}
第二个示例：打开两次并使用相同的端口创建一个appium驱动程序，并在创建驱动程序时出错
for( 2 times){
int port = getSamePort() // Using Same port
StartAppiumUsingPort(port)
driver = CreateAppiumDriver()
PerformTest()
CloseAppiumDriver()
CloseAppium()
}
APK.java
public class APK {
public static void main(String[] args) throws Exception {
AppiumDriver<MobileElement> driver = null;
DesiredCapabilities caps = null;
APK apk = new APK();
AppiumServerJava appiumServer = new AppiumServerJava();
for (int i = 0; i < 2; i++) {
System.out.println("======== " + i + " ==============");
String appiumURl = null;
int port = 4723;
if (!appiumServer.checkIfServerIsRunnning(port)) {
appiumURl = appiumServer.startServer(port);
} else {
System.out.println("Appium Server already running on Port - " + port);
}
// Storing required values
Map<String, String> params = new HashMap<String, String>();
params.put("platform_", "ANDROID"); // IOS || ANDROID

AppiumServer.java
public String startServer(int port) throws Exception {
