I tried this code:
public static readonly CefSharp.Settings Settings = new CefSharp.Settings();
public static void InitCef()
{
if (CEF.Initialize(Settings))
{
CEF.RegisterScheme("fs", new FsSchemeHandlerFactory());
CEF.RegisterScheme("param", new ParamSchemeHandlerFactory());
CEF.SetCookie(#"https://mydomen.com", "mydomen.com", "test", "test1", new DateTime(2100, 1, 1));
}
}
but no reaction. I don't know why. I read many posts and there weren't solution of my problem, nothing works. Please, help me.

and sorry if this is a somewhat easy question, but I'm still new to CaliburnMicro and EventAggregator is proving to be the worst thing to learn by a long mile. Anyway, let's go to it. I have an app with a main ShellView and a bunch of ChildViews that display various information, and I need certain parameters to be shared between the Views. It did not take very long to find I need to use EventAggregator, but with Net6 I could not make it work, no chance. I found this app someone else did in Net3.1 and CaliburnMicro where a new window is created, on this second window there is a TextBox and a send button. Whatever you type here gets sended to the Main window. I studied the code and replicated the app succesfully, also with the latest version of Caliburn and Net6.
BUT then I decided to modify the app and instead of having a new window, now I have exactly the same but with a ChildView inside the ShellView, and here is where nothing works.
1st on the Bootstrapper
public class Bootstrapper : BootstrapperBase
{
private SimpleContainer _container;
public Bootstrapper()
{
Initialize();
}
protected override void Configure()
{
_container = new SimpleContainer();
_container.Singleton<IWindowManager, WindowManager>();
_container.Singleton<IEventAggregator, EventAggregator>();
_container.PerRequest<ShellViewModel>();
}
protected override object GetInstance(Type service, string key)
{
var instance = _container.GetInstance(service, key);
if (instance != null)
return instance;
throw new InvalidOperationException("Could not locate any instances.");
}
protected override IEnumerable<object> GetAllInstances(Type service)
{
return _container.GetAllInstances(service);
}
protected override void BuildUp(object instance)
{
_container.BuildUp(instance);
}
protected override void OnStartup(object sender, StartupEventArgs e)
{
DisplayRootViewFor<ShellViewModel>();
}
As seen, I've created a SimpleContainer, then initialised it as a Singleton.
Also _container.Singleton<IWindowManager, WindowManager>(); is no longer needed as I am not opening a new window anymore, so that could be commented but as I had so many issues, I let it be just in case for this last try before posting this question.
2nd I've created a class for the message IHandle to manage.
public class EventMessage
{
public string Text { get; set; }
}
3rd I created and edited the ChildViewModel (still called SecondWindowViewModel as this experiment is directly derivated from the original worknig one) and ChildView (well SecondWindowView still). Note that SecondWindowView is a WPF User Control, not a Window.
class SecondWindowViewModel : Screen
{
private readonly IEventAggregator _eventAggregator;
private string _secondTextBox;
public string SecondTextBox
{
get { return _secondTextBox; }
set { _secondTextBox = value; NotifyOfPropertyChange(() => SecondTextBox); }
}
public SecondWindowViewModel(IEventAggregator eventAggregator)
{
this._eventAggregator= eventAggregator;
}
public void SendBack()
{
EventMessage ToSend = new EventMessage();
ToSend.Text = SecondTextBox;
_eventAggregator.PublishOnUIThreadAsync(ToSend);
}
As seen, I have an IEventAggregator _eventAggregator, then on the constructor of the class I added this._eventAggregator= eventAggregator; and then on the method SendBack that is called upon pressing the button I send the message with SubscribeOnUIThread.
And lastly the ShellViewModel:
public class ShellViewModel : Conductor<Object>, IHandle<EventMessage>
{
private readonly IEventAggregator _eventAggregator;
private string _parentText;
public string ParentText
{
get { return _parentText; }
set { _parentText = value; NotifyOfPropertyChange(() => ParentText); }
}
public ShellViewModel(IEventAggregator eventAggregator)
{
ActivateItemAsync(new SecondWindowViewModel(_eventAggregator));
_eventAggregator = eventAggregator;
_eventAggregator.Subscribe(this);
}
public Task HandleAsync(EventMessage message, CancellationToken cancellationToken)
{
ParentText = message.Text;
return Task.CompletedTask;
}
//public void NewWindow()
//{
//WindowManager wm = new WindowManager();
//SecondWindowViewModel swm = new SecondWindowViewModel(_eventAggregator);
//wm.ShowWindowAsync(swm);
//}
}
}
Now here instead of inheriting from Screen and IScreen, I inherit from Conductor because I want to have that ChildView on my form. NewWindow is how it worked before but now that button no longer works as I don't need to launch a new window anymore, that's why it is commented out.
As seen, on the contructor I subscribe _eventAggregator, and then HandleAsync does the job of receiving the message and assign it to a variable. Now on the Caliburn Documentatin the method to use is public void Handle() but that no longer works, that's the only way I managed to make it work.
Now when I run this the app does load and seems to work just fine, but as soon as the SendBack() method gets called (in SecondWindowViewModel) the line _eventAggregator.PublishOnUIThreadAsync(ToSend); launches an exception System.NullReferenceException: 'Object reference not set to an instance of an object.'
From my understanding EventAggregator should not care if I'm sending the message to a Window or a user panel or anything. Only thnig I changed is commenting out NewWindow and deleting the old SecondWindowWiew WPF Window and replacing it with a new SecondWindowView WPF User Control with the exact same XAML, then in ShellWiev added bellow a <ContentControl x:Name="ActiveItem"/>.
I'm a bit of a loss here, I've been trying everything, coping the code from the documentation, looking for tutorials online, other StackOverflow questions, and while I could make the UI load and make HandleAsync work, for 3 days straight I could not make it work with ChildViews. That code I wrote does work with a new window. I even run into problems of ShellView straight up not loading unless putting a new constructor that takes no parameters and empty inside, but that's for another day.
Sorry for the extra long post, but I think it's important to put all the information out there. Thank you for your time and again, sorry if this is somewhat of a dumb question, but we all have to start somewhere no?
I have a WPF application that features several pages. Navigation takes place after selecting some of the buttons. I am able to start the testing session successfully and to find elements in the main window. However, when clicking the "OK" button that should trigger navigation to another page, the app does not navigate and the test case fails to find UI elements in the next page. I have tried ImplicitWait and Thread.Sleep but the elements still cannot be found. It seems like the app does not navigate at all when the button is clicked.
Any ideas on how to tackle this issue? Below is what I have accomplished so far:
namespace TestDAAC
{
[TestClass]
public class UnitTests
{
protected const string WINAPPDRIVER_URL = "http://127.0.0.1:4723";
private const string DAAC_APP_ID = #"C:\Users\Admin\Desktop\VC PROJECTS\daac\DAAC\bin\x64\Release\DAAC5.exe";
protected static WindowsDriver<WindowsElement> daacSession;
[ClassInitialize]
public static void Setup(TestContext context)
{
if (daacSession == null)
{
var appiumOptions = new AppiumOptions();
appiumOptions.AddAdditionalCapability("app", DAAC_APP_ID);
appiumOptions.AddAdditionalCapability("deviceName", "WindowsPC");
daacSession = new WindowsDriver<WindowsElement>(new Uri(WINAPPDRIVER_URL), appiumOptions);
}
}
[TestMethod]
public void SequenceOfSteps()
{
daacSession.FindElementByName("OK").Click();
Thread.Sleep(5000);
// daacSession.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(5);
daacSession.FindElementByName("New Imaging Session").Click();
}
}
}
I was able to find the reason why my test cases were not working. WinAppDriver is compatible only with Windows 10 Home or Pro. My target device runs on Windows Enterprise.
Please forgive me as I am still very new to the world of test automation. I have started out by using Selenium WebDriver with JUnit4, predominately on windows OS, although I have modified my scripts and ran them on Mac.
I want to be able to create a set of classes containing set data such as usernames, passwords, default url . Perhaps even calling them from an excel file, but for now Im happy to store the data in classes and then pass that data into other test classes. Im guessing this would be a framework of some sort.
Currently I am writing classes that all begin with something like:
public class ExampleSQATest{
public static Chromedriver chrome;
#BeforeClass
public static void launchBrowser(){
System.setProperty("webdriver.chrome.driver", "chromedriver/chromedriver.exe");
chrome = new ChromeDrievr();
}
#Test
public void aLogin(){
chrome.manage().window().maximize();
chrome.navigate().to("http://mydummywebsite.com");
new WebDriverWait(chrome, 10).until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector
("input#UserName")));
WebElement username = chrome.findElementByCssSelector("input#UserName");
username.sendKeys("username");
WebElement password = chrome.findElementByCssSelector("input#Password");
password.sendKeys("password");
WebElement submit = chrome.findElementByCssSelector("input[type='submit']");
submit.click();
}
}
I will then proceed to write further test methods which requires entering data, but I'd like to be able to call this data from somewhere else that is already predefined.
Can anyone provide any suitable suggestions to investigate so I can learn. Something that is a guide or tutorial. Nothing too advanced, just something that helps me get started by advising me how to set a class of methods to be called by other classes and how it all links together as a framework.
Many thanks in advance.
One way to do this
public abstract class TestBase
{
private readonly INavigationManager navMgr;
private readonly IWindowNavigator windowNav;
private readonly ILoginManager loginMgr;
// All your stuff that is common for all the tests
protected TestBase()
{
this.navMgr = WebDriverManager.Get<INavigationManager>();
this.windowNav = WebDriverManager.Get<IWindowNavigator>();
this.loginMgr = WebDriverManager.Get<ILoginManager>();
}}
[TestFixture]
internal class QueriesTest : TestBase
{
private QueryTests queryTests;
[SetUp]
public void Setup()
{
this.queryTests = WebDriverManager.Get<QueryTests>();
// all the stuff you run specific before tests in this test class.
}
}
Assuming you have created test classes in webdriver-junit4, Use following two classes to call your test classes (Note-Import junit annotations)
1)Create test suite class as -
#RunWith(Suite.class)
#Suite.SuiteClasses({
YourTestClass1.class,
YourTestClass2.class,[you can add more tests you have created...]
})
public class TestSuiteJU {
}
2)Create class to call suite created above as-
public class TestExecution {
public static void main(String[] args) {
Result result = JUnitCore.runClasses(TestSuiteJU .class);
}
}
I have an app I'm working on and it should save and load settings through an XML file (named Settings.txt)
Now, here's the code I use:
public class Settings
{
public bool Selected_64Bit { get; set; }
public bool Supported_64Bit { get; set; }
public bool FirstTime { get; set; }
}
static void SaveSettings(Settings settings)
{
var serializer = new XmlSerializer(typeof(Settings));
using (var stream = File.OpenWrite("settings.txt"))
{
serializer.Serialize(stream, settings);
}
}
static Settings LoadSettings()
{
if (!File.Exists("settings.txt"))
return new Settings();
var serializer = new XmlSerializer(typeof(Settings));
using (var stream = File.OpenRead("settings.txt"))
{
return (Settings)serializer.Deserialize(stream);
}
}
Now, I need to load the settings into a new Settings().
I found out that doing:
Settings [VAR] = new Settings()
will make a new Settings() with all false, but I want to LOAD the saved settings..
I'm confused and can't explain this to myself...
The final product should:
Check if settings.txt exists
If it does - LOAD SETTINGS into a new Settings called Setting (in my case).
If it doesn't - Make new settings and then save them.
I hope someone understood and can help me.
BTW - I'm not so good in C#, and I don't get the get\set thingy at all, as of return and other methods like that.. I know the basics and I'll be happy if I won't need more complicated techniques.
And if I must use more complicated techniques - please explain them deeply because I DO NOT KNOW.
As you have it set up, you'd need to do:
Settings mySettings = Settings.LoadSettings();
This will run your static LoadSettings method and return a Settings object.
As Matt already wrote
Settings mySettings = Settings.LoadSettings();
will do the job.
If you have a application you could use its settings as well. You get that settings by Properties.Settings.Default and in your project settings you can define some properties.
New to WPF/XAML and looking to build a Command library for my application. Current version of my application is "flat" meaning all the code behind resides in my MainWindow.cs file. I've decided to separate things out into User Controls and all the UI part so far works great but....
I'm having trouble binding my commands to things now that I've done this. To make it simple I created a new WPF project, added my Menu control (Controls\Menu.xaml) and referenced this in my MainWindow.xaml. Now, I've gone ahead and added a CommandLibrary class and can't seem to get anything working. Here is my File -> New command code:
public static class MyAppCommands
{
private static RoutedUICommand _NewItem;
static MyAppCommands()
{
_NewItem = new RoutedUICommand("Create a new project", "NewItem", typeof(MyAppCommands));
}
public static RoutedUICommand NewItem
{
get { return _NewItem; }
}
private string filePath = null;
private bool dataChanged = false;
public static void NewItem_Executed(object sender, ExecutedRoutedEventArgs e)
{
if (dataChanged)
{
string sf = SaveFirst();
if (sf != "Cancel")
{
ClearState();
}
}
else
{
ClearState();
}
}
public static void NewItem_CanExecute(object sender, CanExecuteRoutedEventArgs e)
{
e.CanExecute = true;
}
public static void BindCommandsToWindow(Window window)
{
window.CommandBindings.Add(new CommandBinding(NewItem, NewItem_Executed, NewItem_CanExecute));
}
Where do I put the below in my class as a lot of my command will be using them...?
private string filePath = null;
private bool dataChanged = false;
Many Thanks!
I think you could benefit from setting up some design patterns like MVC or MVVM.
Check out these frameworks:
Caliburn (my favorite)
Prism
You can also follow MVC or MVVM just using a couple small helper classes, check out ariticles around the web, like this one MVVM.
Check this if you want a light-weight framework: MVVM Foundation
