I am new to automation and want to create an automation test which can do following:
Open one tab --- click and get some info from that tab
Switch to another tab --- click and get some info from this tab now.
Compare the infos.
We use Page Object Model to get info from one page. However the moment, I switch to another tab -- it switches the tab successfully but does not locate any element on it.
Any idea ?
Questions I would ask is,
Is the element locator correct?
Is this a unique element locator?
Is this a synchronization issue? Are you waiting enough for the page to load before finding the element?
Is this problem particular to a browser? Is it consistent across?
Also make sure you pass on the driver object from one page object to the other. Like,
public class PageOne {
public PageOne(WebDriver driver) {
//do something in constructor
}
public void someMethodInPage1() {
driver.findElement(By.id("button1")).click();
PageTwo pageTwo = new PageTwo(driver);
pageTwo.someMethodInPage2();
}
}
public class PageTwo {
private WebDriver driver;
public PageTwo(WebDriver driver) {
//do something in constructor
this.driver = driver;
}
public void someMethodInPage2() {
driver.findElement(By.id("button2")).click();
}
}

I'm working on a project for iOS using mvvmcross.
App navigation goes like this: first it starts from the splash screen (1), them it navigates to (2), a view to select between 3 options, in view (3) and (4) you get a list and also could navigate back to (2), if you select an item in (3) you navigate to (5) in a modal way.
Lastly, all navigation end up in (6), a view with an hamburger menu.
So I have traditional navigation(with back button), modal views and a hamburger menu at the end.
It would be great if someone could help me or guide me to see how to create a custom presenter for this navigation scheme.
I'm using MvxModalNavSupportTouchViewPresenter and a SlidingPanelsNavigationViewController, but don't know how to swap them when I navigate from (2,4,5) to (6)
A presenter is just something that implements https://github.com/MvvmCross/MvvmCross/blob/develop/MvvmCross/Core/Core/Views/IMvxViewPresenter.cs
public interface IMvxViewPresenter
{
void Show(MvxViewModelRequest request);
void ChangePresentation(MvxPresentationHint hint);
}
This is are really simple interface and it allows shared portable code like ViewModels to request changes in the display.
For the case where you want a Show request to change the entire UI from one display paradigm (modal navigation controller) to another (sliding panels), then one way to do this is to implement a presenter which has two child presenters and which simply switches them over.
In pseudo code this might look like:
public class MyPresenter : IMvxViewPresenter
{
private IMvxViewPresenter _currentPresenter;
private ModalPresenter _modalPresenter;
private SlidingPresenter _slidingPresenter;
private enum Style
{
Modal, Panels
}
private Style _currentStyle;
public MyPresenter()
{
// do whatever you need to do here to:
// - construct _modalPresenter and _slidingPresenter
// - make _modalPresenter attached to the window (via root view controller)
// - make _slidingPresenter hidden/unattached
_currentStyle = Style.Modal;
_currentPresenter = _modalPresenter;
}
public void Show(MvxViewModelRequest request)
{
if (_currentStyle == Style.Modal &&
request.ViewModelType == typeof(WhateverViewModelIndicatesTheSwitchIsNeeded))
{
DoSwitch(request);
return;
}
_currentPresenter.Show(request);
}
public void ChangePresentation(MvxPresentationHint hint)
{
_currentPresenter.ChangePresentation(hint);
}
private void DoSwitch(MvxViewModelRequest request)
{
// do whatever is necessary to:
// - remove _modalPresenter from the window
// - add _panelPresenter to the window
// - show `request` within _panelPresenter
_currentPresenter = _panelPresenter;
_currentStyle = Style.Panelsl
}
}
Obviously, there are some details to fill in within this pseudo-code - e.g. there are some viewcontrollers to be added and removed from the window - but this is just standard iOS manipulation - e.g. see lots of questions and answers like Changing root view controller of a iOS Window and Change rootViewController from uiviewcontroller to uinavigationcontroller
In the N+1 video #34 (Progress), there was an example of using CreateBindingSet() for the Android version, which is not typical. But the narrator also mentioned briefly that the same can be done on the Windows platform.
As much as I tried, however, I am unable to get a View's property to be bound to its ModelView on the Windows Phone. I always get a NullReferenceException.
The closest I came was the code below, including suggestions from ReSharper. Here's my FirstView.xaml.cs:
using Cirrious.MvvmCross.Binding.BindingContext;
using Whatever.ViewModels;
namespace Whatever {
// inheriting from IMvxBindingContextOwner was suggested by ReSharper also
public partial class FirstView : BaseView, IMvxBindingContextOwner {
public class MyBindableMediaElement
{
private string _theMediaSource = "whatever";
public string TheMediaSource
{
get
{
return _theMediaSource;
}
set
{
_theMediaSource = value;
}
}
}
public FirstView()
{
InitializeComponent();
_mediaElement = new MyBindableMediaElement(this.theMediaElement);
var set = this.CreateBindingSet<FirstView, FirstViewModel>();
// the corresponding view model has a .SongToPlay property with get/set defined
set.Bind(_mediaElement).For(v => v.TheMediaSource).To(vm => vm.SongToPlay);
set.Apply();
}
public IMvxBindingContext BindingContext { get; set; } // this was suggested by ReSharper
}
I get a NullReferenceException in MvxBaseFluentBindingDescription.cs as soon as the view is created. The exact location is below:
protected static string TargetPropertyName(Expression<Func<TTarget, object>> targetPropertyPath)
{
var parser = MvxBindingSingletonCache.Instance.PropertyExpressionParser; // <----- exception here**
var targetPropertyName = parser.Parse(targetPropertyPath).Print();
return targetPropertyName;
}
I have not seen a working example of creating a binding set on a Windows Phone emulator. Has anyone gotten this to work? Thanks.
I can confirm that the narrator said that remark a little too flippantly without actually thinking about how he might do it...
However, with a little effort, you definitely can get the CreateBindingSet to work in Windows if you want to.
Before you start, do consider some alternatives - in particular, I suspect most people will use either Windows DependencyProperty binding or some hand-crafted code-behind with a PropertyChanged event subscription.
If you do want to add CreateBindingSet code to a Windows project then:
Add the Binding and BindingEx assemblies to your Ui project - the easiest way to do this is using nuget to add the BindingEx package.
In your Setup class, override InitializeLastChance and use this opportunity to create a MvxWindowsBindingBuilder instance and to call DoRegistration on that builder. Both these first two steps are covered in the n=35 Tibet binding video - and it's this second step that will initialise the binding framework and help you get past your current 'NullReferenceException' (for the code, see BindMe.Store/Setup.cs)
In your view, you'll need to implement the IMvxBindingContextOwner interface and you'll need to ensure the binding context gets created. You should be able to do this as simply as BindingContext = new MvxBindingContext();
In your view, you'll need to make sure the binding context is given the same DataContext (view model) as the windows DataContext. For a Phone Page, the easiest way to do this is probably just to add BindingContext.DataContext = this.ViewModel; to the end of your phone page's OnNavigatedTo method. Both steps 3 and 4 could go in your BaseView if you intend to use Mvx Binding in other classes too.
With this done, you should be able to use the CreateBindingSet code - although do make sure that all binding is done after the new MvxBindingContext() has been created.
I've not got a windows machine with me right now so I'm afraid this answer code comes untested - please do post again if it does or doesn't work.
I can confirm it works almost perfectly; the only problem is, there are no defaults register, so one has to do the full binding like:
set.Bind(PageText).For(c => c.Text).To(vm => vm.Contents.PageText).OneTime();
to fix this, instead of registering MvxWindowsBindingBuilder, I am registering the following class. Note: I have just created this class, and needs testing.
public class UpdatedMvxWindowsBindingBuilder : MvxWindowsBindingBuilder
{
protected override void FillDefaultBindingNames(IMvxBindingNameRegistry registry)
{
base.FillDefaultBindingNames(registry);
registry.AddOrOverwrite(typeof(Button), "Command");
registry.AddOrOverwrite(typeof(HyperlinkButton), "Command");
//registry.AddOrOverwrite(typeof(UIBarButtonItem), "Clicked");
//registry.AddOrOverwrite(typeof(UISearchBar), "Text");
//registry.AddOrOverwrite(typeof(UITextField), "Text");
registry.AddOrOverwrite(typeof(TextBlock), "Text");
//registry.AddOrOverwrite(typeof(UILabel), "Text");
//registry.AddOrOverwrite(typeof(MvxCollectionViewSource), "ItemsSource");
//registry.AddOrOverwrite(typeof(MvxTableViewSource), "ItemsSource");
//registry.AddOrOverwrite(typeof(MvxImageView), "ImageUrl");
//registry.AddOrOverwrite(typeof(UIImageView), "Image");
//registry.AddOrOverwrite(typeof(UIDatePicker), "Date");
//registry.AddOrOverwrite(typeof(UISlider), "Value");
//registry.AddOrOverwrite(typeof(UISwitch), "On");
//registry.AddOrOverwrite(typeof(UIProgressView), "Progress");
//registry.AddOrOverwrite(typeof(IMvxImageHelper<UIImage>), "ImageUrl");
//registry.AddOrOverwrite(typeof(MvxImageViewLoader), "ImageUrl");
//if (_fillBindingNamesAction != null)
// _fillBindingNamesAction(registry);
}
}
This is a skeleton from Touch binding, and so far I have only updated three controls to test out (Button, HyperButton and TextBlock)
How do I modify the SuspensionManager object in a Metro App, to SaveState for the MainPage only and discard State and Navigation for any child pages?
E.g. I have a MainPage that allows you to Navigate to a ChildPage. If the Metro App is Closed or Suspended, I want the ChildPage to override the MainPage state values.
Now, the next time the user opens the app, the MainPage should open and not the ChildPage. Also the MainPage should show State that the ChildPage updated before the app was Closed or Suspended.
Any ideas on how the SuspensionManager object can be safely modified to accomplish this?
Why not just add your data from the ChildPage to the SessionState dictionatry and fill it into the MainPage when the app resumes ?
You don't even need to modify the SuspensionManager for doing that!
public BasicPage1() {
this.InitializeComponent();
Application.Current.Suspending += Current_Suspending;
Application.Current.Resuming += Current_Resuming;
}
void Current_Resuming( object sender, object e ) {
var name = SuspensionManager.SessionState["name"].ToString();
}
void Current_Suspending( object sender, Windows.ApplicationModel.SuspendingEventArgs e ) {
SuspensionManager.SessionState.Add( "name", "danielovich" );
}
Using the suggestion from Danielovich (which is NOT complete), the solution is 2 parts:
Firstly:
No longer save state in the pageState object, instead save state
using the SessionState object. Why? This is so that all Pages can share the same State information.
Secondly:
To ensure, that NavigationState is not saved so that MainPage is always the default page, we need to change the SaveFrameNavigationState in SuspensionManager as follows:
private static void SaveFrameNavigationState(Frame frame)
{
var frameState = SessionStateForFrame(frame);
frame.GetNavigationState();
frameState["Navigation"] = "1,1,0,15,Skycap.MainPage,12,0";
}
I have an application with a popup menu. I'd like to use the popup in the usual way (i.e., it should appear when the user right-clicks anywhere in the window), but I'd also like to attach it to the main MenuBar at the top of the window. I'm not sure how to do this.
I'd thought it would as simple as calling
myJMenuBar.add(myPopupMenu)
but this doesn't work.
JMenuBar.add() wants a JMenu parameter, not a JPopupMenu.
Does anyone have any suggestions?
Instead of trying to reuse the JPopupMenu object, the best approach would be to encapsulate the actions that the menus perform, and reuse those. The popup would trigger those actions, as would the menu items.
From the Action JavaDoc:
In addition to the actionPerformed method defined by the ActionListener interface, this interface allows the application to define, in a single place:
One or more text strings that describe the function. These strings can be used, for example, to display the flyover text for a button or to set the text in a menu item.
One or more icons that depict the function. These icons can be used for the images in a menu control, or for composite entries in a more sophisticated user interface.
The enabled/disabled state of the functionality. Instead of having to separately disable the menu item and the toolbar button, the application can disable the function that implements this interface. All components which are registered as listeners for the state change then know to disable event generation for that item and to modify the display accordingly.
and
JPopupMenu, JToolBar and JMenu all provide convenience methods for creating a component and setting the Action on the corresponding component. Refer to each of these classes for more information.
I had the same issue. A right-mouse-click as well as a top menu with exactly the same (complicated) set of menu items. The 'Action' class is something to consider if you are talking about enablement choices, but it's not dealing with visibility and in my case there was also a dynamic list of entries based on a current selection that I wanted to reuse.
So I ended up implementing a 'Bridge' design pattern (I think) for the methods I actually use (add() and addSeparator()):
public static class MenuBridge
{
private JPopupMenu popupMenu;
private JMenu menu;
public MenuBridge(JPopupMenu popupMenu)
{
this.popupMenu = popupMenu;
}
public MenuBridge(JMenu menu)
{
this.menu = menu;
}
public void addSeparator()
{
if(popupMenu!=null) popupMenu.addSeparator();
else menu.addSeparator();
}
public void add(JMenuItem item)
{
if(popupMenu!=null) popupMenu.add(item);
else menu.add(item);
}
}
So then I can write a reusable method that computes the menu items and synchronize my right mouse click with the top-level menu:
public void addTaskMenuItems(DefaultMenu menu, List<MDProcTask> taskList)
{
...
menu.add()/menu.addSeparator()
...
}
addTaskMenuItems(new DefaultMenu(popupMenu),taskList);
...
taskMenu.addMenuListener( new MenuListener() {
public void menuCanceled(MenuEvent menuevent)
{
}
public void menuDeselected(MenuEvent menuevent)
{
}
public void menuSelected(MenuEvent menuevent)
{
taskMenu.removeAll();
addTaskMenuItems( new DefaultMenu(taskMenu),getSelectedTasks());
taskMenu.revalidate();
}});
I have a client-server application and i am using swing in the client side. My swing client has one main window (jframe) and lots of panels, toolbars and menubar in it.
I want to remove all client action/mouse events (or simply grab and do nothing) while client is waiting response from server by means of glasssPane.
Here is the code i wrote:
private final static MouseAdapter mouseAdapter = new MouseAdapter()
{
public void mouseClicked(MouseEvent e)
{
System.out.println("MouseClicked..!");
}
};
private static Cursor WAIT_CURSOR = Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR);
private static Cursor DEFAULT_CURSOR = Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR);
and
public static void startWaitCursor(JComponent comp)
{
MainWindow root = ((MainWindow) comp.getTopLevelAncestor());
root.getGlassPane().setCursor(WAIT_CURSOR);
root.getGlassPane().addMouseListener(mouseAdapter);
root.getGlassPane().setVisible(true);
}
public static void stopWaitCursor(JComponent comp)
{
MainWindow root = ((MainWindow) comp.getTopLevelAncestor());
root.getGlassPane().setCursor(DEFAULT_CURSOR);
root.getGlassPane().setVisible(false);
}
but i am not able to manage the grab mouse events. Changing cursors at the glassPane is working fine but either i am not able to add mouseAdapter or am not able to make glasssPane become to the top level component.
Any idea?
Thanks.
I realized that my code is working but my problem is threading related. My code was something like:
startWaitCursor();
work(); // server request that takes time
stopWaitCursor();
and changed it to:
startWaitCursor();
SwingUtilities.invokeLater(new Runnable() {
poblic void run() {
try
{
work(); // server request
}
finally
{
stopWaitCursor();
}
by doing this modification i could see the settings i made in the startWaitCursor() method while client is waiting response from the server.
But stil there is a small problem. In startWaitCursor() method i desabled key, mouse and focus events for the glass pane but events are still captured by main frame even glassPane is displayed.
addMouseListener(new MouseAdapter() {});
addMouseMotionListener(new MouseMotionAdapter() {});
addKeyListener(this);
setFocusTraversalKeysEnabled(false);
After server response reached to client and stopWaitCursor() method is invoked the events handled in the main frame.
If i disable the main frame of my application while client is waiting than cursor is not being changed to wait_cursor, if i am not disable the main frame then cursor is being changed but the events are queued.
cheers...
After digging swing threads issues couple of days, i finally found the real answer: SwingWorker
Now my final code is something like,
startWaitCursor();
SwingWorker worker = new SwingWorker() {
public Object doInBackground()
{
doWork(); // time consuming server request
return null;
}
public void done()
{
stopWaitCursor();
}
};
worker.execute();
In startWaitCursor() method i set the glasspane visible (with alpha valued background), display a message to warn the user time consuming job is doing, set the cursor to wait_cursor (hourglass) and consume all the key, mouse events. That is it.
And by using SwingWorker my client is actually responsive (it is working as if no server request is made) but since i display the glasspane and consume all key and mouse events it feels like irresponsive.
What a relief.. SwingWorker rocks...
cheers..
