TestAPI Library Usage

  • Artigo

TestAPI . Heard of it? Tried it?... huh

So here is the gist of it. It’s a collection of helper functions that will make testing your applications easier. Now this is an alpha release and is in the first iteration – so we still have a feature backlog J

Currently we support the following 5 scenarios:

Visual Verification

Sample Usage:

// Capture the actual pixels from the bounds of the screen rectangle

Snapshot actual = Snapshot.FromRectangle(windowRect);

// Load the reference/master data from a previously saved file

Snapshot master =

    Snapshot.FromFile(Path.Combine(TestContext.TestDeploymentDir, "Master0.png"));

// Compare the actual image with the master image

Snapshot difference = actual.CompareTo(master);

// Configure the snapshot verifier - It expects a black image with zero tolerances

SnapshotColorVerifier colorVerifier =

    new SnapshotColorVerifier(Color.Black, new ColorDifference());

// Evaluate the difference image

VerificationResult result = colorVerifier.Verify(difference);

 

Input Injection

Includes helpers for mouse and keyboard input

public static class Keyboard

{

    public static void Type(string text);

    public static void Type(Key key);

    public static void Press(Key key);

    public static void Release(Key key);

    public static void Reset();

}

public static class Mouse

{

    public static void Click(MouseButton mouseButton);

    public static void DoubleClick(MouseButton mouseButton);

    public static void Down(MouseButton mouseButton);

    public static void MoveTo(Point point);

    public static void Reset();

    public static void Scroll(double lines);

    private static void SendMouseInput(int x, int y, int data, NativeMethods.SendMouseInputFlags flags);

    public static void Up(MouseButton mouseButton);

}

 

Dispatcher Helpers

These are simple wrappers around the WPF Dispatcher.

public static class DispatcherOperations

{

    public static void WaitFor(TimeSpan time);

    public static void WaitFor(DispatcherPriority priority);

}

 

CommandLineParser

// Sample for parsing the following command-line:

// Test.exe /verbose /runId=10

// This sample declares a class in which the strongly typed arguments are populated

public class CommandLineArguments

{

   bool? Verbose { get; set; }

   int? RunId { get; set; }

}

CommandLineArguments a = new CommandLineArguments();

CommandLineParser.ParseArguments(args, a);

// SAMPLE USAGE #2:

// Sample for parsing the following command-line:

// Test.exe run /verbose /id=10

// In this particular case we have an actual command on the command-line (“run”),

// which we want to effectively de-serialize and execute.

public class RunCommand : Command

{

    bool? Verbose { get; set; }

    int? RunId { get; set; }

    public override void Execute()

    {

    }

}

Command c = CommandLineParser.ParseCommand(args, new Command[] { new RunCommand() });

c.Execute();

 

UIAutomation Helpers

public static class AutomationUtilities

{

    // Methods

    public static AutomationElement FindElementByIndex(AutomationElement rootElement, int index);

    public static AutomationElementCollection FindElements(AutomationElement rootElement, params Condition[] conditions);

    public static AutomationElementCollection FindElementsByClassName(AutomationElement rootElement, string className);

    public static AutomationElementCollection FindElementsByControlType(AutomationElement rootElement, ControlType controlType);

    public static AutomationElementCollection FindElementsById(AutomationElement rootElement, string automationId);

    public static AutomationElementCollection FindElementsByName(AutomationElement rootElement, string name);

}

 

Since this is still in development we are open to feature requests and will implement them based on the most requested. So do give us feedback. Site: https://www.codeplex.com/TestApi
