Unable to run Appium server programmatically

[saikrishna321]

@TikhomirovSergey as you suggested in the previous post i have my node set in Mac OSX path

➜ AppiumParallel git:(master) ✗ node --version
v0.12.7

echo $PATH
/Users/saikrisv/Library/Android/sdk/platform-tools:/Users/saikrisv/Library/Android/sdk/tools:/Users/saikrisv/Library/Android/sdk/platform-tools:/Users/saikrisv/Library/Android/sdk/tools:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

I able to run node command from any path from ma commandline. Below is the code i use to start the server

AppiumServiceBuilder builder = new AppiumServiceBuilder().withAppiumJS(new File("/usr/local/lib/node_modules/appium/bin/appium.js"))
.withArgument(GeneralServerFlag.APP,
System.getProperty("user.dir") + "/build/wordpress.apk")
.withArgument(GeneralServerFlag.LOG_LEVEL, "info").usingAnyFreePort(); /and so on/;
AppiumDriverLocalService service = builder.build();
service.start();

Error :::

Hi @saikrishna321
There is really interesting situation

Are you starting it from the Eclipse for Mac OS?

This code works when I start it from IntelijIDEA/Eclipse for Windows (7&8). When I do the same from IntelijIDEA/Eclipse for Mac OS X it works with IntelijIDEA (I use v14.x).

With Eclipse for Mac OS I catch the same exception (!!!).

So I have two concerns:

• the first is there is a bug of java_client. So we have to get it fixed.
• the second is there is a bug of Eclipse for Mac OS. With the Eclipse for Windows it works (!!!). Maybe there are some settings that should be defined.

@saikrishna321 If you know which settings should be defined please post them here. Also I recommend you to use IntelijIDEA till the root cause is found or use the following method:

service.withDriverExecutable

Anyway everything should work with Maven started from a command line.

[TikhomirovSergey]

It is the problem of Eclipse for Mac OS. As soon as possible I'll post the way to resolve the problem

[TikhomirovSergey]

@saikrishna321
So
As I've mentioned it is the problem of Eclipse IDE (for Mac OS, it is probably for Linux too). Links:

• Eclipse not using PATH
• Is there a way to execute a linux command from Eclipse. StackOverflow
• Java Runtime command line Process. StackOverflow

... and tons of information that Google can find.

Actually I've tried some of these solutions:

1. These fails

1. Then I made a simple configuration

This value was copied from output of

echo $PATH

1. Then it started to work

The same works with this samples.

So I can advice you a few ways to resolve your problem with the test debugging:

1. To configure Eclipse IDE/current project workspace properly

2. To use IntellijIDEA instead of Eclipse

3. To not do something special and set a full path to the certain Node.js instance

   service.withDriverExecutable

@saikrishna321 I'm waiting for your response. If you are agree then I'll close this ticket. Please provide some more details or describe your ideas otherwise.

[saikrishna321]

@TikhomirovSergey Thanks a lot for all the details and helping me out resolve this issue.

1. Setting ANDROID_HOME and PATH into Eclipse environment, helped me debug the code.
2. Running the code from Intellij, had no issues.

Is possible to set different bootstrap-port, the way we set appium_port ?

new AppiumServiceBuilder().
usingPort(4000);

[TikhomirovSergey]

@saikrishna321 Yep

new AppiumServiceBuilder().
withArgument(AndroidServerFlag.BOOTSTRAP_PORT_NUMBER,"Your port number");

Then I'll close this issue. Actually I haven't known about this special thing of Eclipse IDE too :). Thanks! This ticket is marked by lables and information won't be lost.

[pr4bh4sh]

The issue is marked closed now however i have the solution which works perfectly for me without using any configuration in eclipse at all.
I have cooked something using the below link prior to the autolaunch introduced in Java client itself.
http://stackoverflow.com/questions/20922600/execute-adb-command-from-java-program

public class Utils {
    private static final String[] WIN_RUNTIME = { "cmd.exe", "/C" };
    private static final String[] OS_LINUX_RUNTIME = { "/bin/bash", "-l", "-c" };

    private Utils() {
    }

    private static <T> T[] concat(T[] first, T[] second) {
        T[] result = Arrays.copyOf(first, first.length + second.length);
        System.arraycopy(second, 0, result, first.length, second.length);
        return result;
    }

    public static List<String> runProcess(boolean isWin, String... command) {
        System.out.print("command to run: ");
        for (String s : command) {
            System.out.print(s);
        }
        System.out.print("\n");
        String[] allCommand = null;
        try {
            if (isWin) {
                allCommand = concat(WIN_RUNTIME, command);
            } else {
                allCommand = concat(OS_LINUX_RUNTIME, command);
            }
            ProcessBuilder pb = new ProcessBuilder(allCommand);
            pb.redirectErrorStream(true);
            Process p = pb.start();
            p.waitFor();
            BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
            String _temp = null;
            List<String> line = new ArrayList<String>();
            while ((_temp = in.readLine()) != null) {
                System.out.println("temp line: " + _temp);
                line.add(_temp);
            }
            System.out.println("result after command: " + line);
            return line;

        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}

@TikhomirovSergey it would be time saver if this could be integrated with java client.

[TikhomirovSergey]

@pr4bh4sh
Thanks! I'll try this. If everithing is fine I'll propose a fix.

[saikrishna321]

@TikhomirovSergey to trigger the test in parallel i must pass the android device serial as well UDID.

How can i pass this ?

[saikrishna321]

Right now i'm running the parallel tests by using GNU Parallel

https://github.com/saikrishna321/AppiumAndroidParallelExecution

[TikhomirovSergey]

@saikrishna321
It will be cool if you open one more issue with the detailed description. If you have any problem with it please open a new one. Today or tomorrow I'm going to propose the fix of this issue.

[saikrishna321]

@TikhomirovSergey awesome .. i will do that.. closing this ticket

[Paul-Oginni]

It worked for me when I added the PATH variable the way TikhomirovSergey demonstrated in his screenshots.

Hi,

I have posted detailed explanation on starting and stopping Appium server with java code which works in windows as well as in Linux.
http://qaautomated.blogspot.in/2016/01/how-to-start-appium-server-using-java.html

Regards,
Anuja

[jeangb]

@anuja1111 Thank you I've tried your java class and it works with success.
However, I still have the Eclipse bug meaning if I don't set PATH into Eclipse environment, my test won't be able to run on my device.
By the way, do you think it's possible to display the appium server logs elsewhere than the console in Eclipse ? For example in an other view ?
Best regards

[FlexShamil]

Hello guys, I am testing chrome with my app, so as I enter email and password I get keyboard pulled up and I am unable to use pressKeyCode ENTER its just goes red. thats on 1.7.1 version for appium. per appium.io documentations those methods are supposed to be workable.

is there a solution to that?
