使用appium自动化移动应用程序

Question

I am trying to automate an android application using Appium and Cucumber with Java.I have written the code for a functionality and it is working fine. But some times while running the script, it throws an error

org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original err
or: Could not proxy command to remote server. Original error: Error: read ECONNRESET (WARNING: The server did not provid
e any stacktrace information)

Source code:

import com.google.common.base.Function;

public class C754L2D {
    Capabilities c = new Capabilities();
    MobileDriver driver =  c.getDefaultCapabilities();
    Wait wait = new Wait() {
        @Override
        public Object until(Function isTrue) {
            return null;
        }
    };

    @Given("^User taps the toggle button in the live 2D video playing screen$")
    public void user_taps_toggle_button() throws Exception {

        MobileElement allow = (MobileElement) driver.findElement(By.id("com.android.packageinstaller:id/permission_allow_button"));
        allow.click();
        List<MobileElement> list = driver.findElements(By.id("android:id/text1"));
        for(MobileElement ele :list) {
            String text = ele.getText();
            if(text.equals("Live")){
                ele.click();
                break;
            }
        }
        MobileElement panoramicButton = (MobileElement) driver.findElement(By.id("com.jackalopelite.simplecontainer:id/rl_select_2d"));
        panoramicButton.click();
        MobileElement Screen= (MobileElement) driver.findElement(By.className("android.view.View"));
        TouchAction ta = new TouchAction(driver);
        ta.tap(Screen, 531, 357).perform();
        MobileElement toggleButton = (MobileElement) driver.findElement(By.id("com.jackalopelite.simplecontainer:id/fab_player_switch_mode"));
        toggleButton.click();
    }

    public void taps_back_button() throws InterruptedException {

        Thread.sleep(1000);
        MobileElement backButton = (MobileElement) driver.findElement(By.id("com.jackalopelite.simplecontainer:id/iv_cardboard_back"));
        backButton.click();

    }
    @Then("^The transition screen should dismiss and user should be navigated back to 2d live video playing screen$")
    public void dismiss_transition_screen() {

        try{
            MobileElement cameraAngleSelectionButton = (MobileElement) driver.findElement(By.id("com.jackalopelite.simplecontainer:id/rl_player_switch_camera_parent"));
            if(cameraAngleSelectionButton != null) {
                System.out.println("The transition screen is dismissed and user is navigated back to 2d live video playing screen");
            }
        }catch(Exception e){
            System.out.println("The transition screen is not dismissed and user is not navigated back to 2d live video playing screen");
        }
        //driver.quit();
    }

}

This error gets cleared and the script works fine when I close the emulator and open it again. Can anybody help me in this?

Hey please then kill all simulator programmatically after executing testcase. Below code might help you.

/**
 * Stop Simulator
 */
public void stopSimulator() {
    try {
        Runtime.getRuntime().exec("killall \"iOS Simulator\"");
    } catch (IOException e) {
        //e.printStackTrace();
    }
    try {
        Runtime.getRuntime().exec("killall Simulator");
    } catch (IOException e) {
        //e.printStackTrace();
    }
}

If you are openning a specific simulator you can specify this in above code.

For android simulator please use

Runtime.getRuntime().exec("adb emu kill");
