。 我正在使用Appium 1.9.1版本 MacBook Air 10.13.6 Java客户端6.1.0 最新的Seleniumjar文件我正在尝试使用appium硒（java）实现页面工厂模型，但我无法执行任何操作。 Eveytime应用程序已成功在android设备中启动，但启动应用程序后会引发错误。
* ----------
I am adding all class file
Launch application Code
public class AppLaunch {
public static WebDriver mdriver;
public WebDriver launchApplication() {
//-Picking application apk file inside project folder
String rootPath = System.getProperty("user.dir");
File appPath = new File(rootPath+"/apkfile/app-beta-debug.apk");
System.out.println("Print app path " +appPath);
//-Setting capabilities for android application process
DesiredCapabilities cap = new DesiredCapabilities();
cap.setCapability("appium-version", "1.9.1");
cap.setCapability("platformName", "Android");
cap.setCapability("platformVersion", "7.1.1");
cap.setCapability("deviceName", "Moto X Play");
cap.setCapability("app", "/Users/daffolapmac-73/eclipse-workspace/Wapanda_Driver_Automation/apkfile/app-beta-debug.apk" );
cap.setCapability("appPackage", "co.wapanda.android.beta");
cap.setCapability("appActivity","co.wapanda.android.screens.splash.view.SplashActivity");
//-Setting server host and port with default values
String host = "127.0.0.1";
String port = "4723";
try {
mdriver = new AndroidDriver<MobileElement>(new URL("http://" + host + ":" + port + "/wd/hub"), cap);
mdriver.manage().timeouts().implicitlyWait(120, TimeUnit.SECONDS);
} catch (MalformedURLException e1) {
e1.printStackTrace();
}
try {
} catch (Exception e) {
System.out.println("Error " + e.getMessage());
}
return mdriver;
}
public static WebDriver getWebDriverInstance() {
return mdriver;
}
}
------------------------------
Now I am adding Signup page
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.PageFactory;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import io.appium.java_client.pagefactory.AndroidFindBy;
import io.appium.java_client.pagefactory.AppiumFieldDecorator;
public class DriverSignUpPages {
AndroidDriver<MobileElement> driver;
public DriverSignUpPages(WebDriver driver){
this.driver = (AndroidDriver<MobileElement>)driver;
PageFactory.initElements(new AppiumFieldDecorator(driver), this);
}
@AndroidFindBy(className = "UIAKeyboard")
AndroidElement keyboard;
@AndroidFindBy(id = "usernameTextField")
public static AndroidElement username;
}
------------------------------
Now I am adding Test Case Execution file
import org.openqa.selenium.WebDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;
import com.wapanda.pages.DriverSignUpPages;
import com.wapanda.setup.AppLaunch;
public class ValidateDriverProcess {
AppLaunch applaunch;
DriverSignUpPages dprocess;
WebDriver driver;
@BeforeMethod
public void launchApplication( ) {
applaunch = new AppLaunch();
applaunch.launchApplication();
}
@Test
public void validateDriverSignupProcess() {
try {
DriverSignUpPages dprocess = new DriverSignUpPages(driver);
System.out.println("Inside test case ");
} catch (Exception e) {
e.printStackTrace();
}
}
@AfterMethod
public void closeApplication() {
driver.close();
}
}
When i am launching application with POM page factory i am getting following error
FAILED CONFIGURATION: @AfterMethod closeApplication
java.lang.NullPointerException
