Trumpf.Coparoo.Desktop Library for .NET

logo appVeyorBuildStatus


Trumpf.Coparoo.Desktop is a .NET library for C# that helps you write fast, maintainable, robust and fluent TestLeft-driven UI tests based on the control/page/root-object (Coparoo) pattern.

The library supports all kinds of UI and UI-automation technologies including WPF, WinForms, Web and UIA. In order to run tests you must ensure that the commercial SmartBear's TestLeft® product is installed (free trials are available). For building test projects, e.g. on CI build agents, technically, no license or installation is required.

The following sign-in/out test scenario illustrates how the framework facilitates writing, e.g., a Web test in a "natural" way:

var app = new GitHubWebDriver();                    // create the test driver
app.Open();                                         // open the github page in a new browser tab
app.On<Header>().SignIn.Click();                    // click the sign-in button
app.On<SignInForm>().SignIn("myUser", "abc");       // enter the user credentials ...
app.On<Header>().Profile.Click();                   // open the user profile
app.On<ProfileDrowndown>().SignOut.Click();         // sign out

Just in the same way then the other UI technologies can be tested, and even interact with each other, e.g. for testing WPF apps that integrate with the web.

If you are interested in Web tests only, the following project may be of interest to you: Trumpf.Coparoo.Web.

NuGet Package Information

To make it easier for you to develop with the Trumpf Coparoo Desktop library we release it as NuGet package. The latest library is available on To install, just type Install-Package Trumpf.Coparoo.Desktop in the Package Manager Console.

Getting Started

This library is a derivate of the Trumpf.Coparoo.Web project and can essentially be obtained by replacing Selenium API calls by SmartBear's TestLeft API calls, plus adding wrapper classes for the various UI technologies, like Trumpf.Coparoo.Desktop.WinForms.ViewPageObject and Trumpf.Coparoo.Desktop.WPF.ViewPageObject. Therefore, if you want to get the concepts behind this framework the documentation of the former project is a good starting point:

The following example shows a simple test of the DemoApp test project; source file Tests.cs.

    IDemoApp app = ProcessObject.Resolve<IDemoApp>();
    app.Configuration.WaitTimeout = TimeSpan.FromMinutes(1);
    app.Configuration.PositiveWaitTimeout = TimeSpan.FromMilliseconds(500);
    app.On<IMainWindow>().IncrementButton.Text.WaitFor(text => text == "0", "Text is '0'");
    foreach (var i in Enumerable.Range(1, 4))
        app.On<IMainWindow>().IncrementButton.Text.WaitFor(text => text == i.ToString(), "Caption should be " + i);
    app.On<IMainWindow>().IncrementButton.Text.WaitFor(text => text == "0", "Text is '0'");
