Get all statemachines with their name and ARN

I want to create some metrics around step functions that we currently have. I was able to make that list using python but for some reason, we are limited to use java in our company.
I want to
List ALL statemachines which are defined in current region for given account. in python i was able to achieve this using
stepFunction = boto3.client('stepfunctions', region_name='eu-west-1')
stepFunction.list_state_machines()
Then from that, i want to list all Tasks for that given statemachine and get some metrics.
In Java, I am unable to find an API reference which will give me ALL statemachines. I was looking at http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/index.html?com/amazonaws/services/stepfunctions/model/ListStateMachinesRequest.html API but no help.

To get the activity tasks for every state machine in your library, you will need to use the describeStateMachine call. Follow this pattern (please excuse the pseudocode):
state_machines = list_state_machines()
for each (state machine arn : state_machines)
sm = describe_statemachine(state_machine_arn)
/*parse through the definition here and use regex pattern on the arns*/
activityarns = sm.getDefinition().find(/regex/)
metrics.add(sm.arn, activityarns)
endforeach
Hope this helps!

What is the best way to locate element if the app is multi languages?

I'm trying to automate test cases of an android app which is implemented in Both Arabic and English.
I'm using appium, and AndroidDriver. Also I'm using Xpath in major tests.
When I switch to arabic test cases didn't work anymore.
Any suggestion?

The best test tool I used is rational robot. it will catch the component id instead of the image. and 100% correct catching.
For your case, I think you need to separate the functional test and i18n test. the function only test with English, and have special cased for the translation.

Try to figure out the id or class of the element by using monitor.bat, it should be inside your Android sdk. Without seeing your app code it will be difficult to say why it is not clicking in the password field. But if you give the correct Id it should always work irrespective of the language the app is in.

#karthick : this is the code i'm using it works fine. But if i didn't clear password field before start writing password it will be always empty even after sending keys.
public void Credentials(String username,String password)
{
driver.findElement(By.xpath("//android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.ScrollView[1]/android.widget.RelativeLayout[1]/android.widget.LinearLayout[1]/android.widget.EditText[1]")).sendKeys(username);
driver.findElement(By.xpath("//android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.ScrollView[1]/android.widget.RelativeLayout[1]/android.widget.LinearLayout[1]/android.widget.EditText[2]")).clear();
driver.findElement(By.xpath("//android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.ScrollView[1]/android.widget.RelativeLayout[1]/android.widget.LinearLayout[1]/android.widget.EditText[2]")).sendKeys(password);
driver.findElement(By.xpath("//android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.LinearLayout[1]/android.widget.FrameLayout[1]/android.widget.ScrollView[1]/android.widget.RelativeLayout[1]/android.widget.LinearLayout[1]/android.widget.TextView[1]")).click();
}

C# to automate Java application with Java Access Bridge

I have a Java application that I want to automate for testing. Unfortunately, the app window only registers as a SunAWTFrame, which means none of the controls are exposed to typical window analysis and automation tools.
My search has lead me to C# and utilising Java Access Bridge DLLS in a C# program to automate it.
Has anyone had any experience of this?
Oracle provides JavaAccessBridge (JAB) with some DLLS to help with this as I understand it after reading a few articles around the internet. There are some code examples but I'm really not groking it right now. By breaking it down, I think this is what needs to be achieved:
Import / load / parse the JAB dlls
Map functions in the JAB dll to methods / calls within my program
Have the Java application to automate run (with JAB enabled) and get handle of it to my program
Utilise the JAB functions to control the Java application
I don't know C# as well as I know Java, but that's not going to stop me.
If anyone can provide help, guidance, pointers or anything to get me started, that'd be truly awesome.

As of 2019 we have a great tool AccessBridgeExplorer created and open-sourced by google. It's a really good staring point that contains a WindowsAccessBridgeInterop project which encapsulates almost every JAB API into a class oriented, .NET friendly assembly.
One notable thing, AccessBridge.Initialize() must be called in WPF/WinForm UI thread or in your own messaging pump thread, otherwise some methods like AccessBridge.EnumJvms() will always return false/empty.

Building on Stackia's great tip to use Google's AccessBridgeExplorer, Here are some tips to get you going:
Download Access Bridge Explorer
Use the WindowsAccessBridgeInterop.dll in your own (WinForms not Console) project (Add> Project Reference> Select the DLL)
Create a new access bridge object
AccessBridge Java = new AccessBridge();
Initialize the Access Bridge object
Java.Initialize();
Call Application.DoEvents() - A hack to wait for Java.Initialize to complete (My simple understanding is Java Access Bridge Uses a hidden window or similar)
Application.DoEvents(); //this waits for Java Bridge to initilize ;)
Get the handle of the Java Window
(plenty of examples online of how to get a Window Handle in C#)
Get Access to the Java Object that represents the window:
Java.Functions.GetAccessibleContextFromHWND(Handle, out int vmid, out JavaObjectHandle javaObjectHandle);
Get AccessibleWindow Object for Window (so you can find its children)
AccessibleWindow win = Java.CreateAccessibleWindow(handle);
Come up with your own way to cycle through the children, and the childrens children until you find the object you are after:
//Similar to:
foreach(var child in win.GetChildren())
JavaObjectHandle? javaObject = Java.Functions.GetAccessibleChildFromContext(node.JvmId, parentJavaObject, child.GetIndexInParent());
//to get the label or title of the object:
child.GetTitle();
To Interact with an object (eg click a button), do similar to the following:
(please note where it says JavaObject - it means the child java object (eg. to click a button you need to get the JavaObject for that button using GetAccessibleChildFromContext as i mentioned above)
//Get Possible Actions
JavaAutomation.Java.Functions.GetAccessibleActions(VMID, JavaObject, out AccessibleActions accessibleActions);
foreach( var action in accessibleActions.actionInfo)
{
Log.Info($"DoAction: {action.name}");
}
AccessibleActionsToDo accessibleActionsToDo = new AccessibleActionsToDo();
accessibleActionsToDo.actions = accessibleActions.actionInfo;
accessibleActionsToDo.actionsCount = accessibleActions.actionsCount;
//Do Actions
JavaAutomation.Java.Functions.DoAccessibleActions(VMID, JavaObject, ref accessibleActionsToDo, out int failure);

Internationalize a Java Application?

I have a Java Desktop App, the users of the application have the availability to set the aplications language.
By now i manage it in the database, i call the value of a field called - userLanguage - which is an Integer, and when the user has logged in depending on this value i set the corresponding text to each element on the app by using a switch ( case 1: set labels text ENGLISH, case 2: set labels text SPANISH ... etc)
But i've heard that control the language from the database is an insult, and i would like to know which's a nice way to do it, or what's the best way to do so, it doesn't matter how difficult it would be but the efficence of the method to internationallize an app is what metters for me.

I would actually handle this problem using the Java Preferences. It keeps the preferences for each user separately in a system independent way (for you at least). If you use XML you need to create a SAX/DOM parser or if you use a DB you need to use jdbc. Neither XML or the DB is a bad or a tough solution, I just think the preferences are the easiest.
For internationalization, I would use a ResourceBundle that localized for different Locales. It is a pretty big topic see The Java internationalization (I18n) tutorial

Java Preferences is what you are looking for then.
Or, instead of using XML file you can use Properties.
...i've heard that control the language from the database is an insult...
I do not agree with that. I think it is scenario dependent, and in your case I think you should keep it the way it is to avoid unnecessary work, unless there is an absolute need for keeping the preferred idiom outside your DB.

You've received two answers, both of which are plainly wrong. If you have Java Desktop Application, you should this code:
Locale locale = Locale.getDefault(Locale.Category.DISPLAY);
This will give you valid User Interface language for your application - the one user set in his OS preferences. If you want to keep the language in a database or in some kind of preferences, you'll be forcing users to chose language. What for? I've already set what language I want. If you don't have it, let Java fall back to your application's default.
In case you wonder, if you use ResourceBundle, the default would be the one without a Locale in its name. That is unless you override this process by using custom ResourceBundle.Control.

GetDriveType() equivalent in Java

Is there any method which performs similar tasks to the GetDriveType() method of Microsoft Visual C++. I've already gone through the FileSystemView class of Java Swing. But the method available there are limited and does not fulfill my requirement.
So please tell me someone if Java defines any such method for Windows platform or Platform Independent.

You can use File.listRoots() method. It will list all the drives in your system.
And to get detail information about that drive you can use the following code.
List roots = Arrays.asList(File.listRoots());
for(File f:roots)
{
String s = FileSystemView.getFileSystemview().getSystemTypeDescription(f);
}
This code shows the actual information of drives and other PnP devices. Use this link to know more. And according to your question you must be want to know the hardware details of connected drives to PC. Use JNI if you want to do all code in java.

Are you using JDK7?
If so, there is FileStore which returns the type as a String.
However, looking at the source code itself (FileStore.java) there is a warning that the return value might be implementation specific.
